摘要
作为表观遗传学研究的重要内容,组蛋白修饰在维持真核生物基因组稳定性、基因表达调控和染色质结构等方面发挥重要作用。水稻是重要的粮食作物,也是科学研究的模式植物。近年来研究发现,组蛋白修饰参与了水稻生长发育、胁迫应答、产量以及品质形成等重要生物学性状的调控。因此,明确组蛋白修饰在水稻中的遗传和调控机制对于水稻遗传改良具有重要意义。对组蛋白修饰的作用机制以及在水稻中的研究进展进行了综述,并进一步展望了水稻中组蛋白修饰的研究前景,以期为水稻育种提供参考。
As an important type of epigenetics,histone modification plays an important role in maintaining eukaryotic genome stability,gene expression regulation,and chromatin structure.Rice is an important food crop and a model plant for scientific research.Recent studies have found that histone modifications involved in the regulation of many important biological phenomena in rice,including growth and development,stress response,yield and quality formation.Therefore,clarifying the genetic and regulatory mechanisms of histone modifications in rice is of great significance to the genetic improvement of rice.In this paper,the mechanism of histone modification and the research progress in rice were reviewed,and the research prospects of histone modification in rice were further prospected,which can provide reference of rice breeding.
