NAC3 — Capsicum annuum

Summary

CaNAC3 (T459_23792) on pepper chromosome 9 encodes a NAC domain-containing protein 55 with promoter-specific chromatin binding, sequence-specific DNA binding, and transcription cis-regulatory region binding activities. It is associated with carotenoid metabolism and content, fruit size, leaf senescence, chlorophyll degradation and fluorescence, anther and pollen development, root development, and reproductive structure development. The gene is linked to jasmonic acid signaling, regulation of defence response to fungi, virus-induced PTGS, and responses to drought, salt, and combined abiotic stresses. Associations also include stomatal aperture and closure, potassium acquisition, wound healing, abscisic acid sensitivity, proline accumulation, and thermomemory. Studies of related genes in other species connect the family to drought and salt tolerance, seed development, and pathogen resistance, and to age-related resistance.
