TCP14 — Arabidopsis thaliana

Summary

AT3G47620 (TCP14) on Arabidopsis thaliana chromosome 3 encodes a TCP family transcription factor with DNA-binding transcription activator activity. The gene is associated with seed germination, abscisic acid sensitivity, and cytokinin sensitivity and response. TCP14 is associated with the regulation of organ growth, cuticle pattern formation, cutin anabolism, plant ovule morphogenesis, root radial pattern formation, salicylic acid biosynthetic process, immune response, seed maturation, and defence against Gram-negative bacteria. Associations with agronomic traits include grain width, seed set percent, vegetative vigor, drought sensitivity, photoperiod sensitivity, plant male sterility, and viral disease response. The protein localises to the nucleus, cytoplasm, cytosol, mitochondria, and plasma membrane. Studies of related TCP family members in tomato and potato link the family to fruit development, ripening, seed weight, tuber morphology, and resistance to necrotrophic and biotrophic pathogens.
