The Mechanisms of Brassinosteroids＇ Action： From Signal Transduction to Plant Development

引用

Molecular Plant 2011年第4期4卷 588-600页

作者： Cang-jin Yang Chi Zhang Yang-Ning lu jia-Qi jin Xue-lu Wang State Key Laboratory of Genetic Engineering and Institute of Plant Biology School of Life Sciences Fudan University Shanghai 200433 People's Republic of China

Brassinosteroids play diverse roles in plant growth and development. Plants deficient in brassinosteroid （BR） biosynthesis or defective in signal transduction show many abnormal developmental phenotypes, indicating the importance of both BR biosynthesis and the signaling pathway in regulating these biological processes. Recently, using genetics, proteomics, genomics, cell biology, and many other approaches, more components involved in the BR signaling pathway were identified. Furthermore, the physiological, cellular, and molecular mechanisms by which BRs regulate various aspects of plant development, are being discovered. These include root development, anther and pollen development and formation, stem elongation, vasculature differentiation, and cellulose biosynthesis, suggesting that the biological functions of BRs are far beyond promoting cell elongation, This review will focus on the up-to-date progresses about regulatory mechanisms of the BR signaling pathway and the physiological and molecular mechanisms whereby BRs regulate plant growth and development.

饵剂诱杀是防控红火蚁Solenopsis invicta Buren最广泛和最有效的措施。本研究利用一种新型饵剂投放站(简称饵剂站)对比分析红火蚁工蚁对0.08%茚虫威杀蚁饵剂及其载体的搬运量,并使用5 g/巢、10 g/巢、20 g/巢3种剂量的饵剂对田间红火蚁蚁巢进行单蚁巢处理,评价饵剂站对田间红火蚁的饵剂搬运量及防控效果的影响。结果表明,红火蚁工蚁对饵剂站内0.08%茚虫威饵剂及其载体的搬运量少于直接撒施处理方式的搬运量。施药24 h后,红火蚁工蚁对饵剂站内和直接撒施的0.08%茚虫威饵剂搬运量分别为14.84±3.18 g和17.71±5.88 g,差异不显著。使用饵剂站施用10 g、20 g饵剂处理28 d后,工蚁减退率、蚁巢减退率、蚁群级别降低率和综合防治效果均可达到90%以上,与直接撒施处理方式均无显著差异。虽然饵剂站会一定程度上降低红火蚁工蚁对饵剂的搬运量,但却不影响对红火蚁的防控效果,基于其防雨、防潮的优点,饵剂站可显著延长红火蚁防控的窗口期。
