摘要

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。

Fenoxycarb, a carbamate insect growth regulator, inhibits brassinosteroid action.

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.
