Abstract

Brassinosteroids (BRs) are steroid hormones that regulate plant growth, development, and stress resistance. In this study, we evaluated the effect of agrochemicals on dark-induced hypocotyl elongation, which is regulated by BRs, to identify novel chemicals that regulate BR action. We found that the juvenile hormone agonist fenoxycarb inhibited dark-induced hypocotyl elongation in Arabidopsis. Treatment with the same class of juvenile hormone agonist, pyriproxyfen, did not affect hypocotyl elongation. Co-treatment with fenoxycarb and BR partly canceled the fenoxycarb-induced hypocotyl suppression. In addition, gene expression analysis revealed that fenoxycarb altered the BR-responsive gene expression. These results indicate that fenoxycarb is a BR action inhibitor.

苯氧羰基是一种氨基甲酸酯类昆虫生长调节剂,可抑制油菜素甾体的作用。
Brassinosteroids(BRs)是一种调节植物生长、发育和抗逆性的类固醇激素。在本研究中,我们评估了农用化学品对BR调节的暗诱导下胚轴伸长的影响,以确定调节BR作用的新化学物质。我们发现幼激素激动剂苯氧羰基抑制拟南芥暗诱导的下胚轴伸长。用同一类青少年激素激动剂吡丙氧芬治疗,对下胚轴伸长没有影响。苯氧羰基和BR联合处理部分抵消了苯氧羰基诱导的下胚轴抑制。此外,基因表达分析显示,苯氧羰基改变了BR反应基因的表达。这些结果表明,苯氧羰基是一种BR作用抑制剂。
