Recent Advances in Brassinosteroid Research: From Molecular Mechanisms to Practical Applications.

摘要: Brassinosteroids (BRs) are now firmly established as essential regulators of plant growth and development affecting a broad spectrum processes at the molecular, cellular physiological levels. The pace BR research has continued to accelerate since discovery BR-insensitive -deficient mutants in mid 1990’s progress understanding mechanistic details both signal transduction biosynthesis been particularly dramatic. Studies on effect BRs whole physiology, including stress adaptation, continue build early experiments numerous crop species while integrating advances made molecular genetics Arabidopsis. ability manipulate endogenous levels mutant plants affected biosynthetic genes and/or transgenic with altered expression these genes, allowed testing for causal relationships action that were previously only inferred by application exogenous wild-type plants. specific inhibitors phenocopy BR-deficient greatly facilitated types studies
