Comprehensive analysis of single-repeat R3 MYB proteins in epidermal cell patterning and their transcriptional regulation in Arabidopsis. Wang S, Hubbard L, Chang Y, Guo J, Schiefelbein J, Chen JG. BMC Plant Biol. 2008 Jul 21;8:81 ...... By analyzing multiple mutant lines, we report here that TCL1 functions redundantly with other single-repeat R3 MYB transcription factors to control both leaf trichome and root hair formation. On the other hand, ETC1 and ETC3 participate in controlling trichome formation on inflorescence stems and pedicles. Further, we discovered that single-repeat R3 MYBs suppress trichome formation on cotyledons and siliques, organs that normally do not bear any ...... |

Arabidopsis CAPRICE-LIKE MYB 3 (CPL3) controls endoreduplication and flowering development in addition to trichome and root hair formation. Tominaga R, Iwata M, Sano R, Inoue K, Okada K, Wada T. Development. 2008 Apr;135(7):1335-45. ...... CAPRICE (CPC) encodes a small protein with an R3 MYB motif and promotes root hair cell differentiation in Arabidopsis thaliana. Three additional CPC-like MYB genes, TRY (TRIPTYCHON), ETC1 (ENHANCER OF TRY AND CPC 1) and ETC2 (ENHANCER OF TRY AND CPC 2) act in a redundant manner with CPC in trichome and root hair patterning. In this study, we identified an additional homolog, CPC-LIKE MYB 3 (CPL3), which has high sequence ...... |

Comparison of TRY and the closely related At1g01380 gene in controlling Arabidopsis trichome patterning. Esch JJ, Chen MA, Hillestad M, Marks MD. Plant J. 2004 Dec;40(6):860-9. ...... trichomes, while TRY expression is greatly reduced. The mutation in gl3-sst causes a reduced interaction between the GL1 and GL3 proteins and results in fewer leaf trichomes that develop in clusters. The differential expression of TRY and At1g01380 in this mutant can be used to explain how its altered trichome pattern in gl3-sst [corrected] is generated. ...... |

The ENHANCER OF TRY AND CPC1 gene acts redundantly with TRIPTYCHON and CAPRICE in trichome and root hair cell patterning in Arabidopsis. Kirik V, Simon M, Huelskamp M, Schiefelbein J. Dev Biol. 2004 Apr 15;268(2):506-13. ...... putative transcriptional regulators, including the small MYB proteins TRIPTYCHON (TRY) and CAPRICE (CPC), is known to influence the patterning of both cell types. Here, we used an activation tagging strategy to identify a new regulator, ENHANCER OF TRY AND CPC 1 (ETC1). The ETC1 sequence is similar to TRY and CPC, and ETC1 overexpression causes a reduction in trichome formation and excessive root hair production. The etc1 single mutant has no significant phenotype, but it enhances the effect of ...... |

...... which shows that ETC1 function is partially redundant with TRY and CPC. In addition, the etc1 try cpc triple mutant has novel phenotypes, revealing previously unrecognized roles for these regulators in epidermis development. An ETC1 promoter-reporter gene fusion is expressed in the developing trichome and non-hair cells, similar to the expression of TRY and CPC. These results suggest that ETC1, TRY, and CPC act in concert to repress the trichome cell fate in the shoot ...... |
