烟酰胺腺嘌呤二核苷酸(NAD)合成途径和水稻叶片早衰
Nicotinamide Adenine Dinucleotide(NAD) Biosynthesis Pathway and Leaf Senescence in Rice
摘要
Abstract
Leaf is an important photosynthetic organ in rice, and its senescence is initiated by the endogenous genetic and developmental signals and the external environmental stress. Regulation of leaf senescence is a very complicated and delicate process in plants. NAD (nicotinamide adenine dinucleotide), a coenzyme of dehydrogenase, plays an irreplaceable role in glycolysis, gluconeogenesis, Krebs cycle, respiratory chain and other metabolism. The latest researches showed that the NAD biosynthesis in rice is involved in the regulation of the enzyme activity of silencing geneSirtuins, histone H3K9 deacetylation, plant hormone jasmonic acid (JA) and leaf senescence. This paper highlights cell physiological characteristics, enzyme activity of Sirtuins, NAD biosynthesis of plant leaf senescence, and the OsSRT1-NAD and OsSRT1-MeOH-JA regulation pathways of leaf senescence in rice. It is beneficial to elucidation of the molecular mechanism and regulation pathways of leaf senescence, and application of high yield breeding in rice.关键词
