嘿,朋友们!今天要跟大家分享一个激动人心的研究成果,来自北京大学邓兴旺团队和西南大学魏宁团队的合作。他们最近在《PNAS》上揭示了生长素(auxin)如何调控植物的酸性生长机制,这可对植物的形态和环境适应性起着至关重要的作用! 生长素的定义和重要性 ...
IN auxin studies on compounds not possessing a carboxyl group Wain found, in this laboratory, that 2 : 3 : 6-trichlorobenzaldoxime exhibits activity as a plant growth regulating substance.
Auxin is one of the major five plant hormones, mostly present natively as free or conjugated indole-acetic acid (IAA), a tryptophan ... such as shoot and root growth, development, cell expansion ...
Auxins are chemicals that control the growth of plants by promoting cell division and causing elongation in plant cells (the cells get longer).
This is just like phototropism, in that auxin in the root inhibits growth and auxin in the stem promotes growth.
It involves the L-amino acid oxidase (LAO1 ... "We see that the accumulations of auxin is bad because it slows growth. At low concentrations, it actually improves the growth of the algae, but ...
