ABR1 — Capsicum annuum

Summary

CaABR1 (T459_13838) on pepper chromosome 5 encodes an ethylene-responsive transcription factor 4 with an AP2/ERF domain, and is annotated as a DNA-binding transcription coactivator. It is associated with root regeneration, regulation of nitrogen utilization, cellular response to heat, regulation of seed dormancy, gibberellic acid homeostasis, salicylic acid-mediated signaling, anthocyanin anabolism, hyperosmotic salinity response, phloem transport, and blue light response. The gene is linked to shoot system elongation rate, seed set percent, whole plant size, plant male sterility, flowering time trait, disease tolerance, salt tolerance, leaf senescence trait, and root meristem development. It is associated with abscisic acid signaling, osmotic stress tolerance, seed germination, and pathogen susceptibility. Related genes in other species link the family to ABA sensitivity, osmotic stress tolerance, and seed dormancy.
