植物激素中ABA对植物的衰老有明显的作用，而滞绿基因SGR的超量表达也

植物激素中ABA对植物的衰老有明显的作用，而滞绿基因SGR的超量表达也会引起植物叶片的衰老，那么SGR基因的滞绿原因与ABA合成是否相关，这对探索SGR基因的滞绿机理有重要意义。本文以番茄为实验材料，探寻SGR基因在衰老调控与ABA的代谢控制衰老之间的关系。通过对SGR转基因植株、RanBP3转基因植株以及对照A57分别进行外源ABA、ABA抑制剂、水喷施处理，然后对不同处理的植株叶片进行ABA含量、ABA相关基因表达量、生理生化指标的检测。

Plant hormone ABA had obvious effects on plant senescence and SGR-green gene expression can also cause excess plant leaf senescence, the SGR gene synthesis-Green causes and ABA are related, it is important for exploring the SGR mechanism of gene-green. Based on tomato experiment, explore the SGR gene in aging control and control the relationship between aging of ABA metabolism. By SGR, RanBP3 transgenic plants transgenic plants as well as exogenous control A57 ABA, ABA inhibitors, water spraying treatment and ABA of leaves of different plants content, expression of genes related to ABA, physiological and biochemical indexes detection.

Plant hormone ABA of aging plants have significant effects, whereas overexpression of stagnant green SGR gene can also cause plant leaf senescence, the stay-green causes and ABA synthesis is relevant SGR gene, which is exploring the SGR gene Lag green mechanism is important. In this paper, Tomato as experimental material to explore SGR gene in the metabolic regulation of aging and ABA control relationship between senescence. By SGR transgenic plants, RanBP3 transgenic plants and control A57 were exogenous ABA, ABA inhibitors, water spraying process, and then the plants leaves of different processing will be ABA content detected related gene expression of ABA, physiological and biochemical indexes.

Obviously the effect of plant hormone ABA on plant senescence, while excessive stay green gene SGR expression can cause leaf senescence, so stay green causes and ABA synthesis of SGR gene is related, it has important significance to explore the mechanism of SGR gene in stay green. In this paper, tomato as experimental material, to explore the relationship between SGR gene regulation in aging and ABA metabolism control aging. Based on the SGR transgenic plants and RanBP3 transgenic plants and control A57 were exogenous ABA, ABA inhibitor, water spraying, and then leaves of different treatments of ABA content and ABA gene expression detection, physiological and biochemical indexes.
