Plant Development: Brassinosteroids Go Out of Bounds
نویسندگان
چکیده
Patterning in plants requires defining boundary domains that separate and organize the development of the neighboring organs. Two papers now show how the interplay between brassinosteroid phytohormones and frontier genes contributes to boundary formation in plants.

Plant Chromosomes: Brassinosteroids in the spotlight
Brassinosteroids are plant natural products with structural similarities to animal steroid hormones. They are found throughout the plant kingdom, and when applied exogenously at nanomolar to micromolar levels in a number of test systems, they exhibit a wide spectrum of physiological effects, including a marked promotion of cell elongation [1]. Like animal steroid hormones, brassinosteroids regu...
متن کاملBrassinosteroids – A new class of phytohormones
Brassinosteroids are a new group of plant hormones with significant growth-promoting activity. Brassinosteroids were first isolated and characterized from the pollen of rape plant, Brassica napus L. Subsequently, they have so far been reported from 44 plants and are regarded probably ubiquitous in the plant kingdom. Brassinosteroids are considered as hormones with pleiotropic effects, as they i...
متن کاملPlant Hormones: The Interplay of Brassinosteroids and Auxin
Interplay between hormones is crucial for the coordination of plant development. Recent work has provided important new insights into the close relationship between brassinosteroid and auxin signalling pathways in plants.
متن کاملThe mechanisms of brassinosteroids' action: from signal transduction to plant development.
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 othe...
متن کاملDwarfism and cytochrome P450-mediated C-6 oxidation of plant steroid hormones.
BRs (brassinosteroids) are plant steroid hormones that are essential for normal plant development. The dramatic dwarfism exhibited by mutants in the CYP (cytochrome P450) enzymes involved in BR biosynthesis indicates a role for these hormones in plant growth and development. Since the mid-1990s, collaborative research has been geared towards developing a better understanding of the CYP85 class ...
