The phytochrome gene family, which is in Arabidopsis thaliana, consists of phytochromes A-E（phyA to phyE）, regulates plant responses to ambient light environments. PhyA and phyB have been characterized in detail, but studies on phyC to phyE have reported discrepant functions. In this study, we show that phyD regulates the Arabidopsis gravitropic response by inhibiting negative gravitropism of hypocotyls under red light condition. PhyD had only a limited effect on the gravitropic response of roots in red light condition. PhyD also enhanced phyB-regulated gravitropic responses in hypocotyls. Moreover, the regulation of hypocotyl gravitropic responses by phyD was dependent upon the red light fluence rate.

Evaluation of seedling emergence is a common method used to investigate the vegetation restoration potential of soil seed banks. Previous studies have primarily been conducted in the laboratory using a single water treatment. However, when this method is used, it is dificult to optimize the water conditions for the needs of the individual species of seeds. Additionally, the germination conditions for seedlings in the laboratory are different from those in nature. To avoid these issues, we conducted experiments to activate soil seed banks in the field using different water treatments. The results revealed that: (1) generally, the number of species and quantity of seedlings decrease gradually as the water supply decreases, but that for several species most seedlings did not appear when they were provided with the greatest amount of water, and (2) different species present different germination characteristics. According to the rate of seedling emergence, the species were classified into two germination types: fast and slow. In addition, each species also had a unique climax period of emergence, which was delayed with a decrease in water supply. Therefore, the amount of water provided is vital to seedling emergence, and various water treatments should be evaluated when studying the characteristics of different species in soil seed banks. For the lower reaches of the Tarim River, the optimal soil moisture for seedling emergence ranged from 23. to 28%, and seedling conservation should be strengthened during the climax period of emergence (9-15 days from the day when water became available). These results highlight the importance of the use of an optimal water treatment and demonstrate the danger of using a single treatment method. Our results also emphasize the need for a preliminary study prior to conducting studies to evaluate seed banks.

唐安西大都护府虽先后两次设于龟兹境内,却非一地。第一次存在时间不足四年( 658 - 662) ,当时大都护府尚无独立城堡,而与龟兹都督同治于龟兹都城,今库车县皮朗遗址。安西大都护府第二次创立意义重大,延亘115 年( 693.-808) ,自此成为唐朝在西域的军事、政治中心。本文研究对象就是这时安西大都护府治地。根据伯希和在豆勒豆尔奥库尔遗址出土的汉文文书,参考同一遗址出土的日本藏汉文文书,足以证实这座位于今库车、新和两县交界处的豆勒豆尔奥库尔遗址又名"明府城",意为"朝廷城",应即定型化的安西大都护府治所。

为评价狼尾草抗旱能力,筛选优异资源,以3.份狼尾草材料为对象,研究其PEG-6000胁迫下种子发芽特性,采用隶属函数法和聚类分析对狼尾草抗旱性进行综合评价。结果表明,5%的PEG-6000浓度处理下,狼尾草的发芽率、萌发指数、发芽指数较对照显著增加,表现为促进效应;随着干旱胁迫的增加,各材料发芽受抑作用明显。狼尾草胚芽长和胚根长随PEG浓度的增加呈逐渐下降趋势,其中胚芽较胚根对干旱更敏感。依据测定指标差异程度和变异系数,表明15%的PEG-6000是狼尾草萌发期抗旱性鉴定的适宜浓度。在此浓度处理下,3.份狼尾草综合评价值在0.027~0.942之间,其中LW3.最高,LW29最低。通过聚类分析所有材料被分为3.,其中LW4、LW9、LW11、LW3.、LW42、LW20-2和LW21-1属抗旱材料,可作为狼尾草抗旱性新品种选育的基础材料。

Vesicular exocytosis is a key process involved in neurotransmitter release,whereas vesicle recycling is critical for the homeostasis of plasma membrane structures and the maintenance of ***^2+ regulates several fundamental cellular processes(Zhu et al.,2016,Xiong and Zhu,2016).Especially,Ca^2+ influx plays a dual role of triggering vesicular exocytosis and modulating compensatory endocytosis in neurons and endocrine cells.
