Transgenic Plants02:50

Transgenic Plants

7.0K
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...

科学领域:

  • 昆虫学
  • 分子生物学
  • 生物化学

背景情况:

  • 两点蜘蛛 (Tetranychus urticae) 是一个重要的农业害虫.
  • 农药耐药性,特别是代谢耐药性,是害虫管理的一个重大挑战.
  • 了解耐药性机制对于开发可持续的控制策略至关重要.

研究的目的:

  • 调查阿巴梅克丁和Profenofos耐药性中的代谢性耐药性的作用.
  • 识别涉及农药耐药性的特定基因.
  • 阐明对阿巴梅克丁耐药性的分子机制.

主要方法:

  • 在现场群体中对TuCCE50进行基因表达分析 (定量PCR).
  • 通过RNA干扰 (RNAi) 来抑制TuCCE50的表达.
  • 使用阿巴梅克丁和普罗芬的敏感性测定.
  • 对 TuCCE50 蛋白与阿巴麦丁的同质模型和分子对接.

主要成果:

  • 在耐药的T. urticae野外种群中,TuCCE50基因显著过度表达.
  • 艾巴梅克丁暴露增加了TuCCE50的表达;在一个度下,profenofos表现出类似的效果.
  • 降低TuCCE50增加了对阿巴麦丁的敏感性,而不是对普罗芬的敏感性.
  • 分子对接表明TuCCE50通过特定的残留物与阿巴麦丁结合.

结论:

  • TuCCE50基因的过度表达是T.
  • 由TuCCE50介导的代谢耐药性有助于农药耐药性的演变.
  • 这项研究提供了农业害虫耐药性的分子基础.
