概括
植物根的倾斜,一个关键的根架构特征,是由射击 (K +) 积累调节的. 缺乏核糖体蛋白RPL13aC的突变体由于较低的K+水平减少了根倾斜,影响了高关联性K+ TRANSPORTER 5 (HAK5) 表达.

- 植物生理学 植物生理学
背景情况:
- 植物根系架构对于营养获取至关重要,并且适应环境条件.
- 根倾斜在*Arabidopsis thaliana*是一个垂直的生长行为受营养的可用性影响,但其调节还没有完全理解.
研究的目的:
- 调查根倾斜的调节机制,以应对营养条件.
- 识别涉及营养介导根系架构调整的基因和途径.
主要方法:
- 对*Arabidopsis thaliana*对核糖体蛋白RPL13aC和高关联性K+转运器5 (HAK5) 的突变进行分析.
- 离子分析以确定芽和根中的 (K+) 含量.
- 实验性操纵包括射击首,K+供应限制和K+补充.
主要成果:
- 核糖体蛋白RPL13aC的突变体表现出根倾斜性降低和K+含量降低.
- 射击K +限制和砍头在野生类型植物中显著减少了根倾斜.
- 在rpl13ac突变体中减少HAK5的表达和K+补充恢复了突变体和K饥饿植物中的根倾斜.
结论:

Cell Signaling in Plants
5.7K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
