- 摘要:
- 非生物胁迫中能够影响植物产量和生长的因素包括高盐、干旱、低温等。过低的环境温度对植物造成低温胁迫,进而影响植物的生长、发育、产量以及种子品质。在调控表达真核生物基因的过程中,DNA的甲基化起到了关键性的作用,并且是参与构成表观遗传学的主要成分。为使植物更好地适应冷胁迫,创造抗寒性新种质,通过对国内外植物NDA甲基化以及低温胁迫的研究进展进行综述,对应对低温胁迫,开展表观遗传研究提出展望。
- Abstract:
- Abiotic stresses,such as drought,salinity and chillling,negatively influence survival,biomass production and crop yield.Low temperature or cold stress,causes cold damage to plants,and affects plant growth,development,as well as quality of seed.In the process of regulating the expression of eukaryotic genes,DNA methylation is an important component of the epigenetic,and it plays a key role in regulating gene expression.In order to make plants better adapt to cold stress,new germplasm with cold resistance was created.This paper briefly discusses the relationship between Plant Chilling Stress and plant DNA methylation,and advances in research at home and abroad.And put forward the prospect of how to deal with low temperature stress and carry out epigenetic research.
