NAC5 — Glycine max

Summary

GmNAC5 (GLYMA_06G114000V4) on soybean chromosome 6 encodes a NAC-domain transcription factor with sequence-specific DNA binding and protein homodimerization activity. The gene is associated with regulation of DNA replication, abscission, seed maturation, anther development, and systemic acquired resistance, as well as responses to salt stress, fungal defence, and hypersensitivity. It has been linked to grain protein content, seed size, root dry weight, hydrogen peroxide content, and leaf water potential. Associations with cotyledon opening, hypocotyl elongation, leaf senescence, chlorophyll degradation, drought resistance, pathogen resistance, and starch accumulation have been reported. Studies of related genes in other species connect the family to thermomorphogenesis, thermomemory, brassinosteroid catabolism, abscisic acid biosynthesis, and carbon starvation response. The protein localizes to the nucleus.
