RAO2 — Glycine max

Summary

GmRAO2 (GLYMA_10G219600V4) on soybean chromosome 10 encodes a NAC-domain transcription factor with sequence-specific DNA binding, transcription cis-regulatory region binding, and protein homodimerization activities. It localizes to the nucleus, ER membrane, and plasmalemma. The gene is associated with positive regulation of leaf senescence, abscisic acid homeostasis, cellular response to hydrogen peroxide, retrograde response, salicylic acid-mediated signaling, secondary cell wall biogenesis, root cap development, and aspartate family amino acid anabolism. It has been linked to seed protein content, seed size, plant height, leaf relative water content, stem dry weight, and specific leaf weight. Associations also include salt stress response, oxidative stress tolerance, drought tolerance, aluminum tolerance, leaf development, shoot biomass, and nitrogen assimilation. Related genes in other species are associated with mitochondrial retrograde signaling, stress tolerance, and growth regulation.
