概括

暴露于阿巴麦丁的双斑蜘蛛虫在几代人之间显示出减少的耐药性. 这种跨代效应即使在暴露停止后也持续存在,但DNA甲基化并不涉及.

科学领域:

农业昆虫学农业昆虫学
虫害管理虫害管理虫害管理
表观遗传学在表观遗传学中,表观遗传学是指表观遗传学.

背景情况:

双斑蜘蛛 (Tetranychus urticae) 是一个重要的农业害虫.
防虫剂耐药性的快速发展使害虫控制策略复杂化.
跨代的表型可塑性和表观遗传机制可能会影响耐药性.

研究的目的:

调查跨代表型可塑性在Tetranychus urticae中的阿巴麦克丁耐药性中的作用.
分析T. urticae的甲基组,以评估DNA甲基化对阿巴麦克丁反应的参与.

主要方法:

建立了Tetranychus urticae的同卵性种群.
连续七代的虫暴露于阿巴麦丁.
分析了受治疗和未经治疗的虫种群的甲基组.

主要成果:

观察到一种不适应的跨世代表型反应:暴露于阿巴梅克的虫显示出抵抗力下降.
减少耐药性的表型在暴露后的两代人中持续存在.
甲基组分析显示,细胞因子甲基化的程度很小或不存在,这表明它不参与这种跨代反应.

结论:

跨代的表型可塑性显著改变了T. urticae表型.
在这项研究中,阿巴麦克丁耐药性的发展并非由DNA甲基化直接介导.
需要进行进一步的研究,以阐明虫虫杀虫反应中跨代表型的机制.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
