Gene Details:

  • Gene ID: Pbr038701.2
  • Gene Symbol: PbrMYB132
  • Gene Name:
  • Genome:
  • Species: Pyrus bretschneideri

Functional Descriptions:

  • Auxin inhibits lignin and cellulose biosynthesis in stone cells of pear fruit via the PbrARF13-PbrNSC-PbrMYB132 transcriptional regulatory cascade.
  • PbrMYB132 activated the expression of gene encoding cellulose synthase (PbrCESA4b/7a/8a) and lignin laccase (PbrLAC5) binding to their promotors.
  • As expected, overexpression or knockdown of PbrMYB132 increased or decreased stone cell content in pear fruit and SCW thickness in Arabidopsis transgenic plants.
  • The ‘PbrARF13-PbrNSC-PbrMYB132’ regulatory cascade mediates the biosynthesis of lignin and cellulose in stone cells of pear fruit in response to auxin signals and also provides new insights into plant SCW formation.
