三氯内酯信号抑制 6-磷酸三卤糖信号,而不依赖于 BRC1,从而抑制嫩枝分枝。
植物激素赤霉内酯(SL)抑制嫩枝分枝,而信号代谢物 6-磷酸三卤糖苷(Tre6P)则促进分枝。Tre6P和SL信号如何相互作用以及可能涉及哪些分子机制,在很大程度上仍是未知数。拟南芥 SL 突变体的转录谱分析显示,与野生型(WT)植物或 brc1 突变体相比,Tre6P 通路中高度富集了一组差异表达基因。在园豌豆(Pisum sativum)SL 突变体的腋芽中,Tre6P 相关基因的表达也存在差异。与其他 SL 突变体或 WT 植物相比,SL 信号突变体腋芽(最大)生长 2 中的 Tre6P 水平升高,这表明 MAX2 依赖性 SL 信号在调节 Tre6P 水平中发挥作用。提高 Tre6P 水平的转基因方法表明,所有 SL 突变株系和 brc1 都提前开花,这表明所有这些突变体都对 Tre6P 有反应。Tre6P的升高导致WT植株的分枝增加,但max2和max4突变体的分枝却没有增加,这表明SL途径与Tre6P对嫩枝分枝的调控之间存在某种依赖关系。相比之下,Tre6P 的升高会导致 brc1 突变体的分枝表型增强,这表明 BRC1 和 Tre6P 之间是独立的。本文提出了一个模型,即 SL 信号通过 Tre6P 抑制分枝,而与 BRC1 通路无关。

期刊介绍: New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
