高浓度CO2下植物内源激素响应机制研究进展
Response Mechanisms of Elevated CO2 Concentration on Endogenous Hormones of Plants
摘要
Abstract
With the development of industrialization,especially the rapidly increasing use of fossil fuels,the atmospheric carbon dioxide concentration is rising.The continuous increase of CO2 concentration will impact the growth and development of plants largely,and the coordination of various hormones in plants is key to regulate plant growth and development.Therefore,it is significant and promising to study the change of endogenous hormone content and the intrinsic response mechanism of plant after elevated atmospheric CO2 concentration.At this stage,the research on plant root morphology,growth and development under high CO2 concentration is widespread,but few studies have been done with plant endogenous hormones.This paper reviewed the research achievements of other scholars,and found that elevated CO2 accelerated the net assimilation rate,improved the net photosynthesis,concurrently accumulated growth-promoting hormones,reduced the growth-inhibiting hormone,which subsequently regulated the allocation of assimilates and promoted the growth of plants.The paper also summarized the effects of elevated CO2 concentration on IAA,GA3,ABA,CK and ET,and analyzed the effects of CO2 on related hormone synthesis and gene expression of signal transduction pathway,including the changes of the contents and the internal mechanism of the endogenous hormones in different plants.The future research directions in this field were also discussed.关键词
