| 摘 要： | 高等植物具有复杂的机制使其对环境的变化做出响应,这种机制是通过长期进化建立起来的.它们能够对出现的生物和非生物胁迫产生响应.在分子水平上,植物对各种胁迫的响应是受多基因表达变化调控的,包括植物激素水杨酸、脱落酸等信号途径在整合、协调植物胁迫过程中起关键作用.近年来的研究表明,在植物响应胁迫这一过程中还进行着表观遗传调控...

| Abstract: | Plants have complex mechanisms to respond to environmental changes,such a mechanism is established through long-term evolution.They can response to biological and abiotic stress.At the molecular level,plants of various stress response are regulated by multiple gene expression,including the plant hormone salicylic acid,ABA signaling pathways in the integration,coordination of plant stress play a key role in the process.Recent studies showed that plant responses to stress are also engaged in the process of ep... |
