2020年10月9日 · 2012年，瑞典科学家Catherine Bellini研究组报道了，GH3.3，GH3.5，GH3.6三个基因是拟南芥下胚轴微调 不定根 起始所必须的关键基因 [5] 。 以此同时，中科院的何祖华教授实验室也揭示了GH3.5在植物和病原菌互作过程中的调节机制。

2022年2月1日 · GH3s encode enzymes that conjugate auxins, jasmonates, and benzoates to amino acids. GH3s convert acyl acceptors to their amide derivatives by two step reaction. GH3s regulate plants physiology and response to abiotic and biotic stress factors. GH3s act by modulating the phytohormones concentration at the pre-receptor level.

2019年7月23日 · Functional characterization of Gh_A08G1120 (GH3.5) through virus-induced gene silencing (VIGS) revealed that the VIGS plants ability to tolerate drought and salt stresses was significantly reduced compared to the wild types.

2022年3月24日 · GH3.3, GH3.5 and GH3.6 have been found to modulate jasmonic acid homeostasis by mediating its conjugation to amino acids (Gutierrez et al., 2012). GH3.5 has been further shown to mediate the conjugation of the auxin phenylacetic acid, and the benzoates salicylic acid and benzoic acid (Westfall et al ., 2016 ).

Arabidopsis thaliana GH3.5 was previously shown to be unusual in that it could adenylate both IAA and the defense hormone salicylic acid (SA, 2-hydroxybenzoate). Our detailed studies of the kinetics of GH3.5 on a variety of auxin and benzoate substrates provides insight into the acyl preference and reaction mechanism of GH3.5.

2020年2月7日 · Here, we isolated a wild apple (Malus sieversii Roem) GRETCHEN HAGEN3 (GH3) gene, MsGH3.5, encoding an indole-3-acetic acid (IAA)-amido synthetase. Overexpression of MsGH3.5 significantly reduced the free IAA content and increased the content of some IAA-amino acid conjugates, and MsGH3.5 -overexpressing lines were dwarfed and produced fewer ...

4 天之前 · 研究 GH3-5 基因的抗旱机制,将能解释两者抗旱表型完全相反的原因。 [方法] 采用液相色谱-质谱联用技术测定了干旱胁迫后 gh3.5-1D 、 dfl1-D 及其对应野生型中水杨酸的含量,同时检测了 gh3.5-1D / NahG 和 gh3.5-1D / npr1 两种双突变体的抗旱性。 [结果] 与野生型相比,干旱胁迫后 dfl1-D 中水杨酸 (SA)的含量没有差异,而 gh3.5-1D 中SA的含量增加了1倍。进一步研究发现, gh3.5-1D 较高的抗旱能力在 gh3.5-1D / NahG 双突变体中丧失,而在 gh3.5-1D / npr1 双突变体 …

2016年11月29日 · In Arabidopsis thaliana, the acyl acid amido synthetase Gretchen Hagen 3.5 (AtGH3.5) conjugates both indole-3-acetic acid (IAA) and salicylic acid (SA) to modulate auxin and pathogen response pathways. To understand the molecular basis for the activity of AtGH3.5, we determined the X-ray crystal str …

gh3基因通过生长素结合的催化活性并使游离的吲哚-3-乙酸（iaa）与氨基酸结合，从而在体内稳态中发挥作用。 结果在我们的研究中，我们鉴定了三种棉花中的GH3基因。
