研究发现，番茄gf突变体有滞绿的表现，番茄滞绿基因LeSGR1已被克隆

研究发现，番茄gf突变体有滞绿的表现，番茄滞绿基因LeSGR1已被克隆并研究了其功能[36]，但是SGR基因是如何产生滞绿这一表型的，目前并不清楚。研究表明，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。

Study finds, GF-green mutant of tomato, tomato-green LeSGR1 gene has been cloned and studied its functions [36], but how the SGR gene produce this phenotype-green, is not clear. Research has shown that plant hormones ABA had obvious effects on plant senescence, and excess of SGR-green gene expression can also cause leaf senescence in plants, 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.

The study found that tomato gf mutant has slow performance green, green tomato gene LeSGR1 stagnation has been cloned and studied its function [36], but the SGR gene is how to generate the stay-green phenotype, is not clear. Studies have shown that the 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 explore SGR lag mechanism green gene 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.
