CPC — Arabidopsis thaliana

Summary

AT2G46410, known as CPC (CAPRICE), encodes a MYB family transcription factor with DNA-binding and protein dimerization activity, localized to the nucleus. In Arabidopsis thaliana, CPC is associated with epidermal cell fate specification, particularly the regulation of trichome spacing and root hair differentiation, as well as lateral inhibition, stomatal complex formation, and flavonoid and pigment biosynthesis. It has been linked to numerous traits including leaf trichome density, root hair density and length, seed color, anthocyanin and flavonoid content, iron concentration, lignin content, starch mobilization, flowering time, and seed dormancy. Studies of related genes in other species associate the CPC family with root epidermal patterning, stomatal formation, anthocyanin production, and epidermal hair differentiation, and with trichome development and pathogen susceptibility.
