Summary: Cultivating drought-tolerant tea varieties enhances both yield and quality of tea plants in northern China. However, the mechanisms underlying their drought tolerance remain largely unknown. Here we identified a key regulator called CsREV, which differentially regulates xylem patterns between leaves and stems, thereby conferring drought tolerance in tea plants. When drought occurs, upregulation of CsREV activates the CsVND7a-dependent xylem vessel differentiation. However, when drought persists, the vessel differentiation is hindered as CsVND7a is downregulated by CsTCP4a. This, combined with the CsREV-promoted secondary-cell-wall thickness of xylem vessel, leads to the enhanced curling of leaves, a characteristic closely associated with plant drought tolerance. Notably, this inhibitory effect of CsTCP4a on CsVND7a expression is absent in stems, allowing stem xylem vessels to continuously differentiate. Overall, the CsREV-CsTCP4-CsVND7 module is differentially utilized to shape the xylem patterns in leaves and stems, potentially balancing water transportation and utilization to improve tea plant drought tolerance.

氢燃料电池汽车续航里程长、能量转换效率高，其燃料可通过可再生能源电解水制取。氢燃料电池汽车的推广应用将促进电力系统消纳不稳定的可再生能源电力。已有文献缺乏对氢燃料生产、储运等不同路径的环境影响全生命周期综合分析。考虑中国当前主要的制氢、输氢和发电技术，根据不同技术组合设计17条氢燃料路径，通过GREET软件对这些路径的生命周期环境影响进行核算。研究表明：路径3（可再生能源发电制氢+液氢槽车输氢）和路径16（可再生能源发电+输电+现场制氢）的环境影响最小，低于纯电动车路径（混合发电+锂离子电动车）和汽油内燃机车路径的环境影响。未来需要进一步降低可再生能源发电制氢的成本，提升这些路径的经济性，从而推动燃料电池汽车低环境影响路径的应用。

After nearly 20 years of exploitation, the reserves of Tuwaishan Gold Deposit have significantly decreased, necessitating exploration to increase reserves. By analyzing the regional metallogenic background and the geological characteristics of the mining area and deposit, it was found that the northeast-trending Gezhen fault controls the distribution of the gold deposit. The Tuwaishan Gold Deposit is divided into 4 ore zones from west to east. The ore bodies are controlled by secondary faults in the hanging wall of Gezhen fault. The barren intervals between ore bodies range from 10 m to 50 m, while the barren intervals along the strike of individual ore bodies range from 40 m to 80 m. The ore bodies are jointly controlled by multiple sets of northeast-trending faults, showing a rhombus grid pattern and reflecting the ore-hosting characteristics at fault intersections. Based on the characteristics and occurrence patterns of 3 delineated ore-hosting columns, the fourth rich ore column is predicted between Exploration Line 10 and 12. Low-grade thin ore bodies and mineralization, as well as small lenticular rich ore bodies, are found between the rich ore columns. According to the approximately equidistant distribution of ore-controlling structures, the lateral extension of ore bodies and the lateral angle, and the segmented enrichment patterns of ore bodies vertically, altered rock type ore bodies can be sought in different enriched ore sections.

Place attachment is a crucial factor in visitors'loyalty to a tourist attraction. As a carrier of numerous symbols of revolutionary memory, a red tourist attraction functions as a memory field. Therefore it is an urgent issue for red tourism to awaken visitors'social memory through red tourism experiences and subsequently foster the feeling of place attachment. Based on a survey from 385 red tourists, this study explores the mediating role of social memory in the relationship between red tourism experiences and place attachment. The survey concludes that (1) red tourism experiences significantly and positively influence visitors'social memory, with positive effects by cognitive, emotional and cultural experiences, (2) visitors'social memory significantly and positively influences their place attachment, (3) certain red tourism experiences have a significant positive impact on visitors'place attachment, in which cognitive and emotional experiences positively affect place attachment, while cultural experiences do not have a direct influence, and (4) social memory mediates the relationship between red tourism experiences and visitors'place attachment, with cultural experiences serving as a complete mediator. Consequently, it is crucial to emphasize the creation of cultural atmosphere to enhance the uniqueness of tourist attractions, focus on interaction and narrative retelling to improve visitors'cognitive and emotional experiences, and activate tourism attraction memories through multiple ways to promote the construction of a comprehensive system of social memory content.

Camellia chekiangoleosa has high oil concentration and oleic acid content, while C. semiserrata has strong growth vigor and resistance. In order to make the utmost of the advantages of C. chekiangoleosa and C. semiserrata and cultivate excellent germplasm materials, the phenotypic traits of 45 F1 hybrid progenies of C. chekiangoleosa and C. semiserrata were analyzed to grasp the phenotypic traits of the hybrid progenies. In addition, SSR markers were used to identify hybrids, and SSR markers that could be used to identify the hybrid progenies of oil tea were screened. The results were as follows: (1)The F1 hybrids of C. chekiangoleosa × C. semiserrata showed tall tree and rapid growth, and their leaf veins, sepals and stigmas were all tended to the traits of the male parent C. semiserrata, while flower and leaf morphologies and other traits were similar to the female parent C. chekiangoleosa, and the characteristics of leaf color and size were between those of the parents. (2)From the 32 SSR markers, eight fully complementary markers that could distinguish parents and determine the origin of offspring were screened out for identification of hybrid progenies, among which the hybrid identification rates of seven markers were as high as 100%, and the hybrid identification rate of one marker was 55. 56%. And 45 hybrid progenies were all true hybrids identified by the complementarity of eight markers. (3)The eight SSR markers were used to verify the ability to identify the hybrid progenies, indicating that it is feasible to use these SSR markers to identify the authenticity of the hybrid progenies of oil tea. This study results provide a reference for interspecies cross breeding of oil tea, and also provide a reference for the SSR marker identification of hybrids of oil tea. [ABSTRACT FROM AUTHOR]
