概括

米品种对园草毒素DIMBOA的耐受性有所不同. 一些大米品种中较高的诱导性谷氨S转移酶 (GST) 活性增强了对这种杂草的抵抗力.

科学领域:

植物科学植物科学
农业学是一种农业学.
生物化学生化学

背景情况:

园草 (Echinochloa crus-galli) 释放DIMBOA,抑制了在田中的米生长.
米不能合成DIMBOA,使其易受这种等位基化学物质的影响.
米品种表现出不同程度的基病变和对DIMBOA的潜在耐受性.

研究的目的:

调查米品种对DIMBOA的不同反应.
探索谷氨S转移酶 (GST) 在米对DIMBOA的耐受性中的作用.
了解大米和农场草之间的基因相互作用的分子机制.

主要方法:

在不同的DIMBOA度下,比较合性 (PI312777) 和非合性 (Lemont) 米的苗木生长.
分析谷氨S转移酶 (GST) 蛋白质表达和活性的变化.
研究过度表达特定的GST基因对大米对DIMBOA耐药性的影响.

主要成果:

低度的DIMBOA促进了PI312777的生长,但对Lemont没有影响.
DIMBOA改变了GST表达,丰富了用于排毒的谷氨代谢途径.
莱蒙特在DIMBOA曝光时表现出更高的基础GST活动,而PI312777在DIMBOA曝光时显示出可诱导的GST活动.
过度表达的GST基因 (Os09g0367700和Os01g0949800) 增强了对DIMBOA.A.的抗药性.

结论:

米品种对DIMBOA表现出可变的耐受性,与等位基水平有关.
在PI312777中,更高的诱导性GST活性有助于其耐受性机制.
增强的GST表达对于大米来说至关重要,因为它可以抵抗DIMBOA等位基因化学物质.

关键词:

Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
