Source Description
UniprotTISSUE SPECIFICITY: Expressed in various aboveground tissues undergoing thickening of the lignified secondary wall such as anthers, filaments of stamens, the base of carpels, styles, the boundaries between siliques and pedicels, the midrib of leaf veins, and inflorescence stems, specifically in interfascicular fibers (sclerenchyma), cells differentiating into vascular vessels, and xylary fibers (secondary xylem). {ECO:0000269|PubMed:16214898, ECO:0000269|PubMed:17237351}.

Source Description
TAIRNAC transcription factor NST1. NST1 and NST2 are redundant in regulating secondary wall thickening in anther walls and siliques. NST1 promoter was detected in various tissues in which lignified secondary walls develop.
UniProtTranscription activator of genes involved in biosynthesis of secondary walls. Together with NST2 and NST3, required for the secondary cell wall thickening of sclerenchymatous fibers, secondary xylem (tracheary elements), and of the anther endocethium, which is necessary for anther dehiscence. May also regulate the secondary cell wall lignification of other tissues. {ECO:0000269|PubMed:16214898, ECO:0000269|PubMed:17237351, ECO:0000269|PubMed:17333250}.

  1. NST1 and NST3 redundantly regulate the secondary wall thickenings in interfascicular fiber of inflorescence stems and secondary xylem of hypocotyls in Arabidopsis without affecting the formation of cells destined to be woody tissues. [NST1]
    [PMID: 17237351]
  2. First line evidence demonstrating that SND1 and NST1 function redundantly in the regulation of secondary wall synthesis in fibers is presented.
    [PMID: 17333250]
  3. NST1 and NST3 regulate the formation of secondary walls in siliques which regulates pod shattering.
    [PMID: 18657234]
  4. These results demonstrate that NST2 together with SND1 and NST1 regulate secondary wall biosynthesis in fibers of stems.
    [PMID: 25751728]
  5. The MYB26 protein is localized specifically to the anther endothecium nuclei and that it directly regulates two NAC domain genes, NST1 and NST2, which are critical for the induction of secondary thickening biosynthesis genes.
    [PMID: 28724622]
  6. Genes controlling SCW formation were activated by the overexpression of LBD30, but not in the LBD30(K226R) mutant. LBD30 enhancement of SCW formation resulted from upregulation of SND1/NST1-mediated transcriptional networks. This study presents a mechanism by which sumoylation of LBD30, mediated by SIZ1, regulates SCW formation in A. thaliana.
