Complementation and protein localization analyses of R3 MYBs in an mutant.

Root hairs play vital roles in plant growth since they enable the efficient absorption of water and nutrients from the soil. Recent advances in research have provided a deeper understanding of the molecular genetic mechanisms underlying root hair differentiation. () and its four homologs, which belong to the gene family and encode R3 MYB transcription factors, play central roles in root hair differentiation.

Identification of six CPC-like genes and their differential expression in leaves of tea plant, Camellia sinensis.

Tea is one of the most consumed beverages worldwide, and trichome formation in tea plant leaves impairs their commercial value. In Arabidopsis thaliana leaves, trichome formation is negatively regulated by the CPC family genes, which encode R3-type MYB transcription factors. Here, we identified six CPC-like genes in a tea plant (Camellia sinensis var.

Function of the TRY C-terminal region artificially fused with its homologous transcription factors inducing root hair differentiation in Arabidopsis.

TRIPTYCHON (TRY) is one of the R3-MYB transcription factors. Its extended C-terminal 19 amino-acid region (CTRY) is considered to affect the ability of root hair differentiation in Arabidopsis. Here, to further understand the function of CTRY, it, together with GFP, was artificially fused with TRY homologs, CPC and ETC1, which do not contain such extended regions and induce root hair differentiation.
