The Role of Messenger RNA Alternative Polyadenylation During Developmental Gene Expression Regulation and Adapdation of Rice

水稻（Oryzasativa）不仅是世界上最重要的粮食作物之一，也是单子叶模式植物。水稻品种japonicaNipponbare和indica93-11为两个水稻亚种代表，广泛的种植于我国的南北区域，对环境与气候形成一定的适应性，在我国形成北粳南籼的生产格局。它们各自具有独自的生理特性和生长周期。转录组为特定生理条件下，细胞中全部转录产物的集合。通过对水稻发育过程转录组的研究，可以全面地了解基因表达调控在水稻发育过程中的调节作用以及对环境适应性。多聚腺苷化是基因在转录形成成熟的转录本之前的加工过程之一，即在转录本的3′末端适当位点进行切割并加上50-250个腺苷酸残基，即poly(A)尾巴，通...Rice is not only one of the most important food crops in the world, but also is the model plant of monocots. Two subspecies of rice (represented by cultivars japonica Nipponbare and indica 93-11) were widely planted throughout China's north and south regions, and it had certain adaptability on the environment and climates. Transcriptome is a collection of all transcripts in cells under specific ph...学位：理学博士院系专业：环境与生态学院_环境科学学号：3332013015390
