NAC40_ARATH | developmental stage | Accumulates in imbibed seeds (PubMed:19704545). Detected in early stages of seed development, especially in the basal tip of immature embryo. Particularly expressed in vascular tissues of inflorescence stems, roots, leaves and petioles (PubMed:17410378). |
NAC40_ARATH | function | Transcriptional activator activated by proteolytic cleavage through regulated intramembrane proteolysis (RIP), probably via metalloprotease activity. Regulates gibberellic acid-mediated salt-responsive repression of seed germination and flowering via FT, thus delaying seed germination under high salinity conditions. |
NAC40_ARATH | subcellular location | Localized primarily in plasma membrane as dormant form and, upon salt stress, is processed into a transcriptionally active and nuclear form after a proteolytic cleavage through regulated intramembrane proteolysis (RIP). |
NAC40_ARATH | tissue specificity | Expressed in seeds, leaves, roots and inflorescence (PubMed:17410378). Expressed in roots, rosette leaves, cauline leaves, shoot apex, stems and flowers (PubMed:17158162). |
