TCP15 — Arabidopsis thaliana

Summary

AT1G69690 (TCP15) encodes a TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP) family transcription factor with DNA-binding transcription activator activity. In Arabidopsis, TCP15 is associated with cuticle pattern formation, regulation of cutin anabolism, plant ovule morphogenesis, root radial pattern formation, negative regulation of organ growth, regulation of salicylic acid biosynthetic process, sporocyte differentiation, pri-miRNA processing, regulation of immune response, lignan anabolism, positive regulation of seed maturation, cell cycle control, and filament development. The gene has been linked to numerous traits including grain width, petiole size, seedling cotyledon number, inflorescence branch arrangement, axillary bud dormancy, drought recovery, leaf weight, floral organ size, seed set percent, whole plant size, and viral disease response. Related genes in other species are linked to fruit development, ripening, and resistance to biotrophic pathogens.
