Magnoliaceae plants in China have a long history of cultivation and rich species of Magnoliaceae plants have high scientific, ornamental, ecological and economic values. However, the existence of many Magnoliaceae plants is threatened due to the limited self-reproductive capacity and habitat destruction. The traditional propagation method is inefficient. Tissue culture technology promotes the conservation and utilization of Magnoliaceae plants. It can be applied in the conservation of endangered resources, breeding and commercial production of clonal seedlings. There are many studies on the in vitro shoot propagation, and the system is relatively perfect. Some studies can achieve rooting seedlings through this way. However, there are few studies on organogenesis, and the problems of callus induction and adventitious bud differentiation have not been solved effectively. Also, there are few studies on the somatic embryogenesis in China. This paper reviewed the research on different regeneration ways of Magnoliaceae plants such as in vitro shoot propagation, organogenesis and somatic embryogenesis. The influences of explant selection, medium selection, growth regulator concentration and culture conditions on in vitro growth of Magnoliaceae plants were analyzed. Meanwhile, the paper summarized the problems and the solutions of rooting and browning, and prospected the future research directions. It will provide theoretical basis and technical reference for rapid propagation of Magnoliaceae plants. [ABSTRACT FROM AUTHOR]

During the process of studying the diatom diversity of Hunan Province, we find that a Cymbella species collected from Xiang River possesses the following diagnostic features:(1)Cells are small and their lengths are less than 29 μm;(2)Valves exhibit slight dorsiventrality;(3)Distal raphe fissures are dorsally deflected;(4)Apical pore fields are very small and composed of 1-3 transapical rows of porelli, which comprise two forms, one is slit-like, similar to the areolae on the valve face, and the other is rounded with internal openings covered by the flap-like silica projections;(5)Striae 10-12/10 μm at the dorsal middle part, 11-13/10 μm at the ventral middle part, and areolae 30-40/10 μm;(6)And 1-2 stigmata exist near the valve ventral central area. After comparing this species with the type population of Cymbella pavanaensis A. Vigneshwaran et al., in this paper, it is identified as C. pavanaensis. This paper provides a clearer knowledge of the ultrastructure of C. pavanaensis, enlarges its geographical distribution region, and reports it for the first time in China. [ABSTRACT FROM AUTHOR]

Plants of the lycophyte genus Phlegmariurus contain the chemical compound Huperzine A, the effective medicinal component treating Alzheimer’s disease, thus with huge economic value. To protect the natural resources, plants of the whole genus are listed as the National Key Protected Wild plants in China. In this paper, we revised the taxonomy of Phlegmariurus distributed in China based on morphological, ecological, and geographical evidence. We recognized 21 species from China, and organized them into four sections. Sect. Fargesiani X. C. Zhang ＆ R. H. Jiang is newly established, and the other three sections were revised based on previous studies, i.e., Sect. Hamiltoniani C. Y. Yang, emend. X. C. Zhang ＆ R. H. Jiang; Sect. Phlegmariurus; and Sect. Squarrosurus（Herter） X. C. Zhang ＆ R. H. Jiang, comb. ＆ stat. nov. We reduced the following taxon names to synonymies of various species of Phlegmariurus: Huperzia medogensis, Phlegmariurus austrosinicus, P. changii, P. nylamensis, P. cancellatus var. minor, P. qiongzhongensis, and P. shangsiensis.

Biodiversity is the material basis for human survival. At present, the conservation of biodiversity is mainly carried out through nature reserves. As an essential supplement to the existing nature reserve systems in China, the mini reserve is an essential means to connect fragmented habitats for animals and plants and maintain the integrity of ecosystems. This study systematically collates and analyzes the organizational structure, system construction, daily work, and preliminary results of the community-based Qu'nan mini reserve through a literature review and field investigations. The results are as follows: (1) The construction of the Qu'nan mini reserve is based on the mindset of “self-construction, self-financing, self-management, and self-benefit”. It is managed mainly by “equal discussion and democratic consultation” which has been recognized and supported by local community residents, the local government, and the outside world. (2) The establishment, construction, and development of the mini reserve have not only enhance the protection awareness of community residents and increase the number and diversity of surrounding animal and plant populations. It also improves the living environment of the Qu'nan community and enriches the spiritual culture of residents, significantly contributing to the protection of local biodiversity and traditional culture. In addition, this paper also discusses the hidden dangers in the construction of conservation communities. Some feasible suggestions are proposed to provide a reference for developing biodiversity conservation and other mini reserves in China. [ABSTRACT FROM AUTHOR]

Under the leadership of the Chinese presidency, the second part of the 15th Conference of the Parties to the United Nations Convention on Biological Diversity (CBD) adopted 62 decisions, in particular Kunming-Montreal Global Biodiversity Framework(KM-GBF), which is based on the theory of transformative changes. KM-GBF, its achievements, gaps, and lessons learned, and the experience and achievements of other relevant multilateral environmental agreements, sets out an ambitious plan to implement broad-based action to bring about a transformation in our societies' relationship with biodiversity by 2030, and draws a new blueprint for global biodiversity governance. This paper provides an interpretation of the three core targets of the framework — the “3030 target” for protected areas, resource mobilisation, and digital sequence information of genetic resources, a brief introduction to the relevant decisions to ensure the implementation of the framework, and recommendations for future conservation actions in China: (1) To strengthen the mainstreaming of biodiversity conservation. Revision of China's Biodiversity Conservation Strategy and Action Plan(2011-2030) is an opportunity to involve the whole government and society in the process and to take action to promote the goals and targets of the KM-GBF; (2) To further develop detailed conservation plans, clarify the scopes, purposes and management measures of conservation areas, and implement responsible authorities and specific measures for implementing the plans. Researches on the Other Effective area-based Conservation Measures (OECMs) are needed to incorporate into the management system for biodiversity conservation; (3) To develop an operational indicator system and monitoring plan in accordance with the monitoring requirements of the framework targets; (4) To continue to strengthen awareness and education on biodiversity conservation, raise public awareness and attention to biodiversity conservation, and promote sustainable production and sustainable consumption in society as a whole; (5) To promote international cooperation vigorously to explore and promote Nature-based Solutions on a larger scale, and find pathways for economic and social development that have positive and beneficial effects on nature.

Petrocodon Hance is one of the famous ornamental flowers, but most of them are assessed as extremely dangerous (CR), or at least above vulnerable (VU) due to climate turbulence and strong interference of human activities. To reconstruct the temporal and spatial changes of the potential suitable areas of Petrocodon since the last interglacial period, and explore the response of the suitable areas to environmental changes, which provided theoretical guidance for the origin of Petrocodon, the study of geographical differentiation, the conservation of unique germplasm resources in China, and the development and utilization of gardens. In this paper, combined with 120 distribution records and 17 environmental variables, the optimal MaxEnt model and geographic information technology (ArcGIS) were used to simulate the suitable areas and distribution pattern of Petrocodon in China and Indo-China Peninsula. Based on stepwise multiple linear regression analysis, redundancy analysis and Monte-Carlo test, the dominant variables affecting the current geographical distribution of Petrocodon were evaluated. The results were as follows: (1) The prediction accuracy of the optimized MaxEnt model was high, and the AUC value was greater than 0.96. The potential suitable areas of Petrocodon for the present distribution are continuous from Southwest China to North Vietnam, scattered in central and southern China and blocky in North Myanmar, of which the South Yunnan-Guizhou Plateau in China was the most suitable. (2) The environmental variables which restrict the geographical distribution of Petrocodon included precipitation of the driest month (bio14), precipitation of the warmest quarter (bio18), precipitation of the wettest quarter (bio16), SD of the temperature seasonality (bio4), min temperature of the coldest month (bio6) and altitude (alt). (3) Under the climate change scenario, the expansion and contraction areas of the suitable habitat of Petrocodon were located in the north and northeast of the current potential distribution area, which were sensitive areas susceptible to climate change. During the last interglacial period, the suitable area of Petrocodon expanded on a large scale, but there was almost no suitable distribution area of Petrocodon in the dry and cold environment during the last glacial maximum. After that, with the aggravation of climate warming, the suitable habitats of Petrocodon increased rapidly to high latitudes, while the suitable habitat in low latitudes decreased. (4) The centroid position of the suitable area for Petrocodon migrated northwards from Yongfu County, Guangxi (110.10° E, 24.69° N) to Chengbu County, Hunan (110.29° E, 26.05° N). To sum up, global warming has a positive impact on the potential distribution area of Petrocodon, but extreme warming will cause the suitable habitat of Petrocodon to shrink, and the niche of Petrocodon will narrow. Southwest China to North Vietnam, which has the advantage of mature karst landform, may be its main refuge. [ABSTRACT FROM AUTHOR]

Corydalis saxicola is a perennial herbaceous plant, which mainly distributed in the karst areas of southwest China. Due to its important ecological and medicinal value, Corydalis saxicola has great prospects for development and utilization. With fragile living environmental condition and anthropogenic harvesting pressure, the wild resource of Corydalis saxicola is on the verge of exhaustion, so it has been included in the list of national key protected wild plants in 2021. In order to explore the causes for the endangerment of Corydalis saxicola and provide reference for its conservation and seedling breeding, this paper investigated the influencing factors on seed germination that including seed preservation methods, chemical pre-treatments, temperature, light, drought, pH, mix with wet sand and refrigerate treatment. The results were as follows:(1)Low-temperature storage can prolonged the seed activity, germination rate of 2-years stored seed could still reached 30%.(2)Germination rates of seed pre-treatments by HCl and NaClO solutions can reached to 50%～60%; germination rate was 50% at 20 ℃, while closed to zero at 30 ℃; darkness was more favorable for seed germination than periodic light condition; the seed germination rate kept decreasing with deepening drought; the seed germination rate did not changed significantly under the conditions of pH 3.0～8.0.(3)Mix with wet sand and refrigerate treatment can significantly promoted the seed germination potential and germination rate, and the germination rate was twofold of the control. In summary, the seed inactivation at room temperature and germination inability at high temperatures above 30 ℃ are more related to its endangerment; efficient seed germination methods can provide an effective way for conservation and industrial application of Corydalis saxicola. The results provide a theoretical and technical guarantee for the conservation of wild Corydalis saxicola, and technically support is cultivation. [ABSTRACT FROM AUTHOR]

As one of the three alpine flowers in the world and one of the ten traditional famous flowers in China, Rhododendron has high ornamental value and broad landscape applications. However, most of them are naturally distributed in high-altitude mountains, and they prefer cool and humid climate for the restriction of genetic mechanism. Drought is the key factor to restrict their ex-situ conservation and landscape application. As Rhododendron have many different species, cultivars and ecological types, distributed in a wide area, the mechanisms of different species or cultivars responses to drought stress are different. In this paper, how Rhododendron responses to drought stress and the effects of exogenous substances on improving the drought resistance of Rhododendron in China and abroad were reviewed from the aspects of seed germination, morphological and anatomical characteristics, physiological and biochemical parameters, gene expression, etc. In addition, the deficiency of current research and the future research directions were also discussed. It is proposed that the water use strategy and drought resistance mechanism of different ecological types and different drought resistances of Rhododendron should be future studied, as well as the gene regulation mechanism of mycorrhizal fungi for improving the drought resistance and the screening of excellent strains. This study provides the basis for the diversity conservation, the exploitation of drought resistance resources and the landscape applications of Rhododendron in China. [ABSTRACT FROM AUTHOR]

Eucalyptus L. Herit is a large genus of Myrtaceae with more than 600 species, native to Australia and some of its northern islands and mainly distributed in tropical and subtropical regions of the world. Eucalyptus has the characteristics of fast growth, high yield, short rotation period and so on. It is an excellent pulp material with remarkable economic benefits. There are many introduced species in China, mainly distributed in South China. Nearly 80 species have been introduced into China since 1890, and are widely distributed in Guangdong, Guangxi, Guizhou, Sichuan, Yunnan, Jiangxi and other places. At present, China has become one of the countries with the largest area of Eucalyptus plants in the world and is also the largest exporter of Eucalyptus oil. Eucalyptus has a lot of industrial value. Its wood, leaves and fruits are important raw materials in chemical industry, fragrance and medicine fields. They can be used for developing high performance Eucalyptus recombination material, bamboo Eucalyptus composite material, pulp and paper-making, etc. Eucalyptus plants are used as folk medicine, with anti-bacterial and anti-inflammatory, wind-relieving and anti-pyretic, anti-corrosion and anti-pruritic effects. As a traditional medicine, Australian aborigines are the first to use Eucalyptus for the treatment of fever and bronchial diseases; in China, the leaves of E. globulus, E. robusta, E. exserta, E. tereticornis, E. citriodora are often used to treat influenza, dysentery, eczema, and injuries for a long time. Pharmacological studies show that Eucalyptus plants have good anti-oxidant, anti-inflammatory, anti-bacterial, anti-viral, anti-tumor, anti-cardiovascular diseases and other pharmacological activities. In this study, 421 non-volatile chemical constituents from different parts of Eucalyptus and their pharmacological activities are classified and described in detail by referring to the domestic and foreign literatures related to Eucalyptus in recent 30 years. There are 73 flavonoids, 61 organic acids, 45 terpenoids, 229 polyphenols and 13 fatty alcohols. Most of the pharmacological activities are anti-oxidant, anti-bacterial, anti-viral and anti-tumor, but the related mechanisms still need to be further elucidated. This study focuses on the medicinal parts of Eucalyptus, fully explores their medicinal value, and carries out clinical transformation and new drug research, which provides scientific basis for further research, development and utilization of Eucalyptus in the future.

Andrographis paniculata, known as ‘Chuanxinlian' in China, is an important southern medicine in China. Its main active ingredients, andrographolide components, has good pesticide effects on heat-clearing and anti-bacterial and anti-inflammatory, etc. Modern medical research has demonstrated that they also have profound effects in anti-HIV, anti-thrombus, liver protection and so on. Because they are difficult to be synthesized artificially, to increase the biosynthesis of andrographolide components in A. paniculata by cultivation regulation and breeding methods is of great significance to improve the quality of this medicinal material. To provide reference for related research in these fields, this paper reviewed the relationship between accumulation of andrographolide components and plant development, the effects of cultivation measures and environmental factors on the accumulation of andrographolide components, and the research advances in biosynthesis of andrographolide components and its molecular regulatory mechanism in the last decade worldwide. We also put forward three aspects which should be focused on in future studies aiming at enhancing the biosynthesis and accumulation of andrographolides components in A. paniculata:(1)To further identify the biosynthetic pathway of andrographolide components and the functions of key genes, and to elucidate the mechanism of andrographolides accumulation at molecular level;(2)To deeply study the laws of growth and development, yield and quality formation, and their interrelations in A. paniculata with the combination of molecular biological approaches and crop cultivation theories;(3)To reveal the signal regulation network in the biosynthesis of andrographolide components.

Bryophytes are important indicators of environmental pollution. At present, bryophytes are mainly used to monitor atmospheric pollution in China. In fact, bryophytes have been widely applied to monitor water quality abroad. In the present paper, we firstly analyzed the literature of applying bryophytes to monitor water environmental quality abroad, then summarized relevant contents of bryomonitoring, which included the types of water pollutants monitored by bryophytes, the species of bryophytes used for bryomonitoring, the influences of the survival status of bryophytes on monitoring effect, the environmental factors affecting the enrichment of heavy metal elements in water by bryophytes, the active and passive methods of applying bryophytes to monitor water pollutions, and the sample preparation, as well as some European cases of bryomonitoring for water environmental quality. Finally we also proposed some suggestions about bryomonitoring researches and application in the future. [ABSTRACT FROM AUTHOR]

Biodiversity conservation is one of the hottest topics all over the world. In order to rescue the most threatened plant species in the wild, to guide the China's biodiversity conservation and to serve the construction of national ecological civilization, a new concept of plant species with extremely small populations(PSESP)was proposed in China, which is attracting the widespread attention internationally in plant species conservation. In the past “13th Five-Year Plan” period, China launched the comprehensive program for rescuing and conserving PSESP. And in the coming 14th Five-Year Plan for National Economic and Social Development and the Long-term Targets for 2035 of the People's Republic of China, the rescue of PSESP is explicitly incorporated into the special aims at the conservation of important ecosystem and ecological restoration. The PSESP rescue and protection is a long-term systematic work with strong science, high technical and professional requirements. For scientifically conserving PSESP, rescue protection and system study should be given an equal weight. Undoubtedly, systematic research on the PSESP conservation is an important task to support their effective conservations. This paper is trying to systematically review the recent research works on the PSESP conservation, focusing on the surveys and assessment of the current populations or individual status(including confirmation of species taxonomic status), eco-biological characteristics, propagation techniques and genetic diversity, with the aim to find new theories and to form new ideas for the PSESP conservation. Finally, three insights into priorities for future conservation research of PSESP in China are proposed, which could be a reference for further PSESP conservation research. [ABSTRACT FROM AUTHOR]

In this paper, the maximum entropy model (Maxent) and geographic information system ( ArcGIS 10.3) softwares were used to predict the potential distribution areas of four Litsea species under the current and future climate conditions of China ( 2061 - 2080), and to analyze and classify their suitable habitats. The results were as follows: Litsea cubeba was widely distributed in the south to the Yangtze Hiver in China, and under the future climate with two ( HCP2.6, HCP8.5) carhon dioxide concentrations, during 2061-2080 the suitable anca for its distribution was reduced by 4.9%and 0.5%, respectively; L. coreana was mainly distributed in central and northern subtropical regions of China, and under the climate scenarios with two carbon dioxide concentrations, in 2061-2080 the total suitable area would be increased by 5.6% and 4.5%, respectively; L. greennumiana was mainly distributed in the south subtropical regions of China; L. mollis was widely distributed in the subtropical region. Under the future climate HCP2. 6 scenarios, the suitable area of the two species would be shrinked by 1.0% and 3.3%, respectively, and under the climale HCP8.5, the suitable area of the two species would be shrinked by 5.6% and 8.3%, respectively. These results reveal that due lo different ecological requirements, Litsea species will have different distributional responses to the future climate. the introduction and cultivation of Litsea species should consider the influences of climale change.
