mRNA选择性剪切在植物发育中的作用

Function of mRNA Alternative Splicing in Plant Development

mRNA选择性剪切(alternative splicing)是生物体基因转录调控的基本方式之一,随着新一代测序技术的广泛应用,越来越多的基因的选择性剪切现象被揭示。在植物发育的不同阶段及其应对外界逆境胁迫的过程中,许多基因发生了选择性剪切,产生植物各个发育阶段所需的特定蛋白质来完成不同的发育过程和形成不同应答因子以适应外界环境的变化。本文从种子发育、器官形态发育、开花时间、生物钟调控、环境胁迫等方面综述选择性剪切在植物发育中的研究进展。

mRNA alternative splicing is one of the basic ways for reg·Lation of gene transcription in eukaryotes. With the wide application of new generation sequencing technology, more and more splicing events are re vealed currently. During different stages of plant development and response to environmental stress, many genes could produce different alternative splicing products to participate in particular developmental processes and response to various environments. In this paper, we reviewed the progress of alternative splicing studies in seed and organ development, flowering time, circadian clock and environmental stress in plant.
