Abstract

Ethylene is one of the important endogenous gaseous plant hormones that regulates various metabolic and developmental processes in plants. In this study, we found that ethylene could promote bud break and improve the antioxidant system in buds, whereas ethylene increased the chlorophyll and carotenoid degradation that led to the leaves senescence. RNA-seq was also used to analyse the grape leaves and buds treated with ethylene. A total of 7457 differentially expressed genes were identified in the two comparison samples. The annotation results showed that differential genes in GO and KEGG were mainly involved in plant hormone biosynthesis, signal transduction, photosynthesis, and secondary metabolism. We developed a possible model for ethylene controlling and senescence of the leaf and the bud dormancy based on the data produced in RNA-seq. It is evident that exogenous ethylene promoted leaf senescence by regulating various hormone signals, particularly ABA, and inhibiting photosynthesis. Compared with leaves, exogenous ethylene tended to promote photosynthesis in buds and secondary metabolism to regulate buds dormancy. This study will be helpful to clarify the possible action mechanism of ethylene regulating the development of leaves and buds. [ABSTRACT FROM AUTHOR]

Abstract

Yangzong Lake is the third largest deep-water plateau lake in Yunnan, China. Rapid socioeconomic development of the basin has resulted in pollution of water environment. This study aimed to identify the carrying capacity of water environment and to conduct the associated optimization of socioeconomic development. The results of this study showed that: (1) The carrying capacities of tributary rivers were small in relation to that of the lake. The maximum allowable annual loads of chemical oxygen demand (COD), ammonia nitrogen (NH3-N), and total phosphorus (TP) into the main rivers of the basin were 449.37, 24.73, and 5.38 tons, respectively. (2) Under the planning scenario, COD and NH3-N loads remain the primary constraints on economic and social development in the watershed. (3) In further optimizing the structure of the plantation industry, focusing on strengthening the collection and treatment capacity of rural domestic sewage, the watershed can achieve high-quality development of the tourism industry. The tourism output value in 2025 and 2035 can carry up to 20.28 billion CNY (growth rate: around 15.44%) and 76.80 billion CNY (growth rate: around 14.64%), respectively. This study can provide basic support for the future economic and social development of the watershed for decision-makers. [ABSTRACT FROM AUTHOR]

Abstract

Ship canals, which play a crucial role in facilitating transport, exert significant and long-term impacts on wetland ecosystems. For social and economic development, numerous countries have put forward plans for ship canals. This paper reviews the literature on the ecological effect of ship canals on wetland ecosystems, identifies research gaps, and suggests future research directions. Ship canals typically involve high construction intensity, usually including river regulation, ship locks, and water diversion for navigation. The ecological effects of ship canals on wetlands refer to changing wetland hydrological processes, degrading water quality, eliminating wetland botany, disturbing wetland animals, and increasing ecological threats. The cumulative impact can either alter the trend of ecological succession or degrade biodiversity. Thus, there is a need for further research to elucidate the mechanisms by which canals affect wetland ecosystems, enhance the practices for wetland protection associated with canals, and develop a robust evaluation system for green canal projects.
