植物生长调节物质对泡桐丛枝病株幼苗形态和叶片蛋白质含量变化的影响

利用患丛枝病的豫杂一号泡桐组织培养苗,研究了植物生长调节物质对其幼苗形态和蛋白质变化的影响.结果表明,植物生长素类物质在一定程度上可以减轻豫杂一号泡桐丛枝病发病的症状,但不同种类的生长素对其减轻的程度存在一定的差异.ABA减轻效果甚微.此外,经植物生长调节物质处理的患丛枝病豫杂一号泡桐幼苗叶片蛋白质凝胶电泳中出现了在对照幼苗叶片中观察不到pI 6.3,31 kD的蛋白质(多肽).这意味着植物生长调节物质处理对患丛枝病泡桐苗木的基因表达产生了影响.

Effects of Plant Growth Regulators on Morphological and Content Changes of Proteins of Witches' Broom of Paulownia Seedlings

This paper dealt with the effects of plant growth regulators on morphological and content changes of proteins of witches' broom of paulownia seedlings.The results indicated that exgeneous auxins,to some extent,might alleviate the symptom of the witches' broom of the seedlings,but the effects of the auxins were different with NAA and IBA.And ABA had little effects on the alleviation of the symptom.Moreover,the protein(pI 6.3,MW 31 kD) which could be observed in leaves of the seedlings with witches' broom appeared in the leaves treated with phytohormones.This meant that the plant growth regulators had effects on the gene expression of the paulownia seedlings with witches' broom.
