(Rho-related GTPases of plants) 的表达,从而在 ABA 途径中起负调控作用,包括 ABA 介导的气孔关闭和干旱响应[69].在 MYB96 受 MIEL1(RING-type E3 ligase)泛素化介导的降解途 径中,ABA 通常会抑制 MIEL1 的表达, 从而促进 MYB96 的积累,使 MYB96 在种子萌发期通过促进 初级种子休眠的正调节因子 ABI4...
螺旋被认为是"识别螺旋", 其负责识别 DNA 结合位点,并以此结构结合在目标 DNA 的主沟中(图 1).根据与动物 c-myb 中 3 个重 复序列 R1,R2 或 R3 的相似性以及 R 重复序列的 数量, 将植物 MYB 家族分为 4 类 :1R-MYB/MYB- related,2R-MYB/R2R3-MYB,3R-MYB/R1R2R3-MYB 和 4R-MYB(图 1)...
Both Htn1 and ZmWAK encode wall-associated receptor-like kinases that confer quantitative resistance against northern leaf blight (NLB) and head smut, respectively (Hurni et al., 2015; Zuo et al., 2015). ZmCCT, which encodes a CCT motif protein, and ZmAuxRP1 (Auxin regulated protein 1) ...
MYB 转录因子基因同时参与调控植物的多种 次生代谢途径,对植物的细胞分化,形态发生和建 成有重要的调控作用.研究表明,葡萄 VvMYBPA1[20],拟南芥 AtMYB7[21]等转录因子基因 均调控原花青素的合成,杨树 PtoMYB156[22]参与 黄酮类物质的合成 , 荷花 NnMYB4[21] 和玉米 ZmMYB31[23]等转录因子基因参与调控木质...
promoters ofMdCHSandMdUFGT. Overexpression of this TF resulted in activation of anthocyanin-related genes. As no causal sequence variant was identified in this MYB, the authors assume that a difference in the methylation of the promoter region of this MYB is responsible for the expression ...
A phylogenetic tree was constructed using the neighbor-joining method with the protein sequences of PtoMYB156 and other MYB factors involved in the regulation of the phenylpropanoid pathways (Fig. 1C). Phylogenetic analysis showed that PtoMYB156 is more closely related to AmMYB30853, EjMYB254...
根据每个MYB蛋白中含有的R结构个数和重复种类的不同,MYB蛋白可分为4R-MYB、2R-MYB (R2R3-MYB)、3R-MYB (R1R2R3-MYB)和1R-MYB (MYB-related)这4类相关蛋白[15]。其中,最小类的4R-MYB蛋白中的每个基因包含4个R1/R2重复序列,且只在极少数植物基因组中进行编码[16],目前仅在模式植物拟南芥[17]、葡萄...
Fig. 1: Amino acid sequence alignment and phylogenetic analysis of FhMYB27, FhMYBx, and other MYB proteins. aMultiple alignment of the amino acid sequences of anthocyanin or proanthocyanidin related MYB repressors. Modified version of FhMYB27 was included: FhMYB27ΔC (C-terminal repression doma...

related TFs that are still unknown. Some resistance-related MYB proteins have been identified inArabidopsis. Overexpression ofAtMYB30leads to hypersensitive cell death inArabidopsis, thereby enhancing resistance toPseudomonas syringae41. Its homologous gene,MdMYB30, also has similar disease resistance ...
