中国水稻研究所水稻基因组模块创新团队研究发现,水稻体内烟酰胺腺嘌呤二核苷酸(NAD:Nicotinamide Adenine Dinucleotide)合成途径受阻能够导致其叶部提前衰老,而对这一途径中的关键限速基因的克隆和功能解析有利于探究一种新的延缓水稻叶片衰老的方法,进而为水稻增产提供新思路。该研究成果2016年4月6日在线发表于《植物生理学(Plant Physiology)》杂志。NAD在水稻细胞氧化还原反应和维持细胞的发育进程中起着重要的调控作用。虽然导致叶片衰老的因素很多,
The Rice Genomics Module Innovation Team at China National Rice Research Institute found that obstruction of the synthesis pathway of Nicotinamide Adenine Dinucleotide (NAD) in rice leads to the premature senescence of its leaf, while the critical speed limit in this pathway Cloning and functional analysis of genes will be helpful to explore a new method to delay leaf senescence of rice and provide new ideas for increasing rice yield. The research was published online April 6, 2016 in Plant Physiology. NAD plays an important regulatory role in rice cell redox reaction and the maintenance of cell development. Although there are many factors leading to leaf senescence,
