Plant Development: Brassinosteroids Go Out of Bounds
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.
متن کاملBRASSINOSTEROIDS: Essential Regulators of Plant Growth and Development.
Brassinosteroids (BRs) are growth-promoting natural products found at low levels in pollen, seeds, and young vegetative tissues throughout the plant kingdom. Detailed studies of BR biosynthesis and metabolism, coupled with the recent identification of BR-insensitive and BR-deficient mutants, has greatly expanded our view of steroids as signals controlling plant growth and development. This revi...
متن کاملBrassinosteroids modulate plant immunity at multiple levels.
U pon detection of microbe-associated molecular patterns (MAMPs), plants usually shift cellular activities from normal growth to defense responses called microbeor pathogen-induced immunity (MTI or PTI) (1, 2). Effective regulation of the tradeoffs between growth and immunity according to physiological and pathological conditions is critical for plant fitness in nature. The leucine-rich repeat ...
متن کاملPlant 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 and plant steroid hormone signaling.
INTRODUCTION Steroids play a role as essential hormones in plants as well as in animals. Plants produce numerous steroids and ste-rols, some of which are recognized as hormones in animals (Geuns, 1978; Jones and Roddick, 1988). Brassinolide (BL) is the most bioactive form of the growth-promoting plant steroids termed brassinosteroids (BRs). Grove et al. (1979) purified 4 mg of BL from ف 40 kg...
