休眠是种子的生物适应习性,受到许多因素的调控.前人对种子的休眠进行了大量的、不同方面的研究,其广度和深度也在不断地扩大和深入.目前为止,随着数量遗传学方法和突变体等手段在种子休眠研究中的广泛使用,大量与休眠相关的数量性状位点(QTL)和突变基因已被识别,这些对于进一步揭示植物种子休眠与萌发的详细机制具有十分重要的意义.简单介绍了近年来关于种子休眠遗传变异研究,并从休眠特异性基因、染色质、种子生长发育及激素这四个不同角度简述植物种子休眠的诱导形成,同时试图从基因和分子水平上阐述环境因素对于种子休眠的作用机制,以及休眠解除的调控机理,以期为种子体眠的研究提供一定的参考.
Research Progress of Molecular Regulation Mechanism of Seed Dormancy
Dormancy is the biological adaptation behavior for seed,and it is regulated by many factors.A lot of studies have been done on various aspects of seed dormancy,and the breadth and width of these studies are in constant expanding and deepening.With the wide application of meansof quantitative genetics method and mutant in the study on seed dormancy,a large number of quantitative trait loci (QTL) and mutant genes related with dormancy have been identified,which is of great significance for the further revelation of the detail mechanisms of plant seed dormancy and germination.This paper briefly introduced the genetic variation of seed dormancy in recent years,described the inductive formation of plant seed dormancy from the four aspects of dormancy specific gene,chromatin,seed growth development and hormone,and stated the action mechanism of environmental factors on seed dormancy from genetic and molecular levels,as well as the regulation and control mechanism of dormancy release,with the aim to provide certain references for the study on seed dormancy.
