RESULTS: Exogenous ABA promoted growth and reduced the feeding behavior of S. avenae nymphs in rice. Our results suggested that enhanced trichome density and increased expression of related genes may be associated with rice resistance to aphids. An analysis of volatiles revealed the production of seven compounds associated with pest resistance.
CONCLUSIONS: These results indicate that ABA reduces aphid feeding in rice. Our findings provide a basis for understanding ABA-mediated defense responses in rice and provide insights on more environmentally-friendly approaches to control. © 2024 Society of Chemical Industry.
结果:外源ABA促进了水稻若虫的生长,降低了水稻的摄食行为。我们的结果表明,毛状体密度的增加和相关基因表达的增加可能与水稻对蚜虫的抗性有关。对挥发物的分析表明,产生了与害虫抗性相关的七种化合物。
结论:这些结果表明ABA降低了水稻中蚜虫的摄食。我们的发现为理解水稻中ABA介导的防御反应提供了基础,并为更环保的控制方法提供了见解。©2024化学工业学会。
