The steroid hormones found in plants, the brassinosteroids, were originally genetically identified about 15 years ago as critical regulators of seedling photomorphogenesis. Two studies now shed light on the molecular mechanisms behind this observation. Brassinosteroids control seedling morphogenesis through direct interaction with master transcriptional regulators downstream of growth-promoting hormones and light signalling.
植物中的甾体激素，即油菜素甾醇，大约 15 年前最初被遗传鉴定为幼苗光形态建成的关键调控因子。现在有两项研究揭示了这一观察结果背后的分子机制。油菜素甾醇通过与生长促进激素和光信号下游的主转录调控因子的直接相互作用来控制幼苗形态发生。
