Abstract

In Arabidopsis thaliana, R3-type MYB genes, CAPRICE (CPC) and its family of genes including TRIPTYCHON (TRY), ENHANCER OF TRY AND CPC1 (ETC1), ETC2 and CPC-LIKE MYB3 cooperatively regulate epidermal cell differentiation. Root hair formation is greatly reduced by a mutation in CPC, and try and etc1 enhance this phenotype. In this study, we demonstrate that CPC, TRY and ETC1 are also involved in root hair formation at the root-hypocotyl junction. The cpc try and cpc etc1 double mutants showed a reduced number of root hairs in that area. Additionally, the expression of ETC1::GUS was higher near this area. These results suggest that CPC family of genes also cooperatively regulates root hair formation at the root-hypocotyl junction in unique ways.

摘要

在拟南芥中，R3型MYB基因、CAPRICE（CPC）及其基因家族，包括TRIPTYCHON（TRY）、TRY和CPC1增强子（ETC1）、ETC2以及类CPC的MYB3，协同调节表皮细胞分化。CPC基因突变会极大地减少根毛形成，而TRY和ETC1会增强这种表型。在本研究中，我们证明CPC、TRY和ETC1也参与根-下胚轴连接处的根毛形成。cpc try和cpc etc1双突变体在该区域的根毛数量减少。此外，ETC1::GUS在该区域附近的表达较高。这些结果表明，CPC基因家族也以独特的方式协同调节根-下胚轴连接处的根毛形成。
