Cotton fiber is a raw material for the global textile industry and fiber quality is essential to its industrial *** are plant secondary metabolites that may serve as dietary components,regulate light harvesting,and scavenge reactive oxygen *** carotenoids accumulate predominantly in rapidly elongating cotton fibers,their roles in cotton fiber development remain poorly *** this study,a fiber-specific promoter proSCFP was applied to drive the expression of GhOR1Del,a positive regulator of carotenoid accumulation,to upregulate the carotenoid level in cotton fiber in *** length,strength,and fineness were increased in proSCFP:GhOR1Del transgenic cotton and abscisic acid(ABA)and ethylene contents were increased in elongating *** ABA downstream regulator GhbZIP27a stimulated the expression of the ethylene synthase gene GhACO3 by binding to its promoter,suggesting that ABA promoted fiber elongation by increasing ethylene *** findings suggest the involvement of carotenoids and ABA signaling in promoting cotton fiber elongation and provide a strategy for improving cotton fiber quality.

GPS掩星探测每天可获得均匀分布全球的折射角资料,不受气溶胶和云雨影响并且可弥补海洋和极地观测资料稀缺问题。因此,基于三维变分方法,采用NCEP的全球再分析资料作为初猜场,利用欧洲中心(ECMWF)的ROPPGPS掩星事件资料处理系统作进行三维气象场的反演研究。实验结果表明,经GPS折射角资料反演后的气象场能明显改善初猜场的温湿分布,有效缩小其与无线电探空观测之间的差异,此结果对于气象工作者具有较大参考意义和实际价值。
