Gene Details:

  • Gene ID:
  • Gene Symbol: BrpSPL9
  • Gene Name: squamosa promoter-binding-like protein 9
  • Genome:
  • Species: Brassica rapa

Functional Descriptions:

  • BrpSPL9-2 (B. rapa ssp. pekinensis SQUAMOSA PROMOTER BINDING-LIKE 9-2), a target gene of microRNA brp-miR156, controls the heading time of Chinese cabbage.
  • Overexpression of a mutated miR156-resistant form of BrpSPL9-2 caused the significant earliness of heading, concurrent with shortening of the seedling and rosette stages.
  • Morphological analysis reveals that the significant earliness of heading in the transgenic plants overexpressing BrpSPL9-2 gene was produced because the juvenile phase was absent and the early adult phase shortened, whereas the significant delay of folding in the transgenic plants overexpressing Brp-MIR156a was due to prolongation of the juvenile and early adult phases.
  • miR156 and BrpSPL9 genes are potentially important for genetic improvement of earliness of Chinese cabbage and other crops.
