Source Description
TAIREncodes a nuclear localized member of the MYB transcription factor family. Involved in positive regulation of aliphatic glucosinolate biosynthesis.Expression is induced by touch, wounding and glucose.
UniProtMajor regulator of short-chained aliphatic glucosinolates (GLSs) biosynthesis. Together with MYB29/HAG3 and MYB76/HAG2, promotes aliphatic glucosinolate biosynthesis but represses indolic glucosinolate biosynthesis. Prevents insect performance (e.g. lepidopteran insect Mamestra brassicae and Spodoptera exigua) by promoting glucosinolates. {ECO:0000269|PubMed:17420480, ECO:0000269|PubMed:17521412, ECO:0000269|PubMed:18042203, ECO:0000269|PubMed:18446225, ECO:0000269|PubMed:20348214, ECO:0000269|PubMed:23580754, ECO:0000269|PubMed:23792303, ECO:0000269|PubMed:23943862}.

  1. Myb28 is a positive regulator for basal-level production of aliphatic glucosinolates.
    [PMID: 17420480]
  2. We hypothesize that HAG1/MYB28 is a novel regulator of aliphatic glucosinolate biosynthesis that controls the response to biotic challenges
    [PMID: 17521412]
  3. MYB76 is not dependent on MYB28 and MYB29 for induction of aliphatic glucosinolates.
    [PMID: 20348214]
  4. Mutant plants deficient in camalexin, indole, or aliphatic glucosinolate biosynthesis were hypersusceptible to S. sclerotiorum, among them the myb28 mutant, which has a defect resulting in decreased production of long-chained aliphatic glucosinolates.
    [PMID: 21418358]
  5. MYB28 and MYB29 synergistically functioned in the glucose-induced biosynthesis of aliphatic glucosinolates, but MYB28 was predominant over MYB29.
    [PMID: 23329848]
  6. MYB28 expression was induced by sulfur deficiency, while the expression levels of MYB29 and MYB76 were positively correlated with sulfur concentration.
