2021年4月2日 · The genome of the model plant Arabidopsis thaliana encodes orthologs of all three core SNAPc subunits, including A. thaliana SNAP complex 4 (AtSNAPc4)-a 4R-MYB-type protein with four-and-a-half adjacent MYB repeat units.

2012年10月10日 · MYB proteins are classified into four major groups namely, 1R-MYB, 2R-MYB, 3R-MYB and 4R-MYB based on the number and position of MYB repeats. MYB transcription factors are involved in plant development, secondary metabolism, hormone signal transduction, disease resistance and abiotic stress tolerance.

2025年2月27日 · Among the MYB TF superfamily, the 3R-MYB subfamily has received much attention for its key role in regulating mitosis. In Arabidopsis thaliana, five genes encode the MYB3R TF, and except for AtMYB3R2, which is associated with circadian rhythms, all MYB3R play important roles in regulating the plant cell cycle (Liang et al., 2005; Matsui et al ...

2015年6月1日 · The 4R-MYB subfamily is the smallest group of the MYB family in plants, each member of which contains four R1/R2 repeats (Fig. 1). Only one 4R-MYB protein was found in several plant species, for example At3g18100 in Arabidopsis (Chen et al., 2006).

2020年1月1日 · According to the number of characteristic MYB units (R-repeats), MYB TFs superfamily are classified into four groups: 1R-MYB, R2R3-MYB, 3R-MYB and 4R-MYB. Among them, R2R3-MYB group is the wider class which harbours two …

2013年4月26日 · All four classes are found in plants, representing the taxon with the highest diversity of MYB proteins. The smallest class is the 4R-MYB group, whose members contain four R1/R2-like repeats. A single 4R-MYB protein is encoded in several plant genomes.

2012年10月10日 · MYB proteins are classified into four major groups namely, 1R-MYB, 2R-MYB, 3R-MYB and 4R-MYB based on the number and position of MYB repeats. MYB transcription factors are involved in plant development, secondary metabolism, hormone signal transduction, disease resistance and abiotic stress tolerance.

4R-MYB 含有4 个R 结构,由 4 个类似R1 或R2结构重复形成,是 MYB转录因子家族中最少的一类,仅在极少数植物中被发现,有关该亚类的功能 注:A.MYB 转录因子N 末端的结构;B.MYB 转录因子C末端的结构。 图1 MYB 转录因子的分类[17] 研究较少[3]。

为探究MYB转录因子在食用菌中的生物学功能,对前期转录组发现的一个编码双孢蘑菇 (Agaricus bisporus)MYB转录因子的基因进行克隆和生物信息学分析。

2024年1月30日 · 本研究首次从双孢蘑菇中克隆到了一种4R型MYB转录因子编码基因（Ab4RMYB），该基因编码区长1 209 bp，编码402 个氨基酸；其蛋白序列含有4 个保守的SANT-MYB 结构域和规律性分布的色氨基酸残基，属于MYB 转录因子家族中的4R-MYB 型，与白环蘑中的4R-MYB 转录因子亲缘 ...
