Abstract

The <i>CAPRICE-LIKE MYB</i> gene family, including <i>CAPRICE</i> (<i>CPC</i>), <i>TRIPTYCHON</i> (<i>TRY</i>), <i>ENHANCER OF TRY AND CPC1</i> and <i>2</i> (<i>ETC1</i> and <i>ETC2</i>), <i>CPC-LIKE MYB3</i>/<i>ENHANCER OF TRY AND CPC3</i> (<i>CPL3</i>/<i>ETC3</i>), encodes a small protein with an R3-type MYB motif that regulates leaf trichome differentiation in <i>Arabidopsis thaliana</i>. To understand the role of <i>CPC-LIKE MYB</i> genes in trichome development, we focused on the effect of these genes on trichome branching and clustering. Trichomes of the <i>try etc1</i> double mutant consistently had more branches than wild-type and the <i>try</i> single mutant, suggesting that the <i>TRY</i> and <i>ETC1</i> genes cooperatively regulate trichome branch development. The <i>ETC2</i> gene has little to no involvement in trichome branching. <i>TRY</i> and <i>CPC</i> are known to have strong effects on trichome cluster formation. Double and triple mutant analyses revealed that the <i>ETC1</i>, <i>ETC2</i> and <i>CPL3</i> genes have some degree of functional redundancy with <i>TRY</i> in trichome cluster formation.
