摘要
叶片是植物进行光合作用的主要器官。水稻生长和发育过程中由叶片提供能量和营养,其过早衰老会直接影响植株光合作用和呼吸作用,从而影响生长代谢过程,导致稻谷产量和品质受到严重影响。通过生物化学等诱变手段产生不同的叶片早衰突变体,并对其突变特性进行研究分析,明确早衰性状的相关调控基因,进一步研究早衰基因的调控机理及功能,为新基因的挖掘创造良好的条件,为育种工作的向前推进提供科学理论基础。本研究从已克隆的和已定位的部分水稻叶片早衰基因综述早衰的发生、过程、分子机制、早衰突变体的应用和展望,为培育抗衰老新品种提供理论基础。
Leaf is the main organ of photosynthesis,respiration and transpiration in plants.Rice leaves provide energy and nutrition during plant growth and development,and their premature senescence will directly affect photosynthesis and respiration of the plant,thus affecting the growth and metabolism process,resulting in a serious impact on rice yield and quality.Through biological chemical mutagenesis means different leaf premature senescence mutants,study and analyze their mutation characteristics,identify the related regulation genes of premature aging traits,further study on the regulation mechanism of premature senescence genes and functions,to create conditions for the discovery of new genes,provide scientific theoretical basis for the advance of breeding work.In this paper,we reviewed the occurrence,process,molecular mechanism,application and prospect of premature senescence mutants in rice leaf from some cloned and localized genes,which will provide theoretical basis for breeding new varieties of anti-senescence.
