卡普赖斯(CPC)编码一个带有R3MYB基序的小蛋白，调节拟南芥的根毛和毛状体细胞的分化。另外6个类似CPC的MYB蛋白，包括TRIPTYCHON(Try)、Try和CPC1的增强子(ETC1)、Try和CPC2的增强子(ETC2)、Try和CPC3的增强子(ETC3/CPL3)、TRICHOMELESS1(TCL1)和TRICHOMELESS2/CPC-like MYB4(TCL2/CPL4)也具有调节拟南芥根毛和/或毛细胞分化的能力。在这篇综述中，我们描述了我们关于CPC-like MYB转录因子如何调控根毛细胞分化的最新发现。最近，我们鉴定了番茄SLTRY基因与拟南芥Try基因同源。含有SLTRY的转基因拟南芥植株产生了更多的根毛，其表型与35S：：CPC转基因植株的表型相似。众所周知，CPC还参与了花青素的生物合成。在转基因植株中，花青素的积累受到抑制，这表明SLTRY也会影响花青素的生物合成。我们的结论是，番茄和拟南芥部分使用相似的转录因子来促进根毛细胞的分化，而且类似CPC的R3MYB可能是植物根毛发育的关键共同调节因子。
CAPRICE (CPC) encodes a small protein with an R3 MYB motif and regulates root hair and trichome cell differentiation in Arabidopsis thaliana. Six additional CPC-like MYB proteins including TRIPTYCHON (TRY), ENHANCER OF TRY AND CPC1 (ETC1), ENHANCER OF TRY AND CPC2 (ETC2), ENHANCER OF TRY AND CPC3/CPC-LIKE MYB3 (ETC3/CPL3), TRICHOMELESS1 (TCL1), and TRICHOMELESS2/CPC-LIKE MYB4 (TCL2/CPL4) also have the ability to regulate root hair and/or trichome cell differentiation in Arabidopsis. In this review, we describe our latest findings on how CPC-like MYB transcription factors regulate root hair cell differentiation. Recently, we identified the tomato SlTRY gene as an ortholog of the Arabidopsis TRY gene. Transgenic Arabidopsis plants harboring SlTRY produced more root hairs, a phenotype similar to that of 35S::CPC transgenic plants. CPC is also known to be involved in anthocyanin biosynthesis. Anthocyanin accumulation was repressed in the SlTRY transgenic plants, suggesting that SlTRY can also influence anthocyanin biosynthesis. We concluded that tomato and Arabidopsis partially use similar transcription factors for root hair cell differentiation, and that a CPC-like R3 MYB may be a key common regulator of plant root-hair development.
