Gene Details:

  • Gene ID: Cs1g03470
  • Gene Symbol: CsDUO1
  • Gene Name: DUO POLLEN 1
  • Genome:
  • Species: Citrus sinensis

Functional Descriptions:

  • The miR159a-DUO1 module regulates pollen development by modulating auxin biosynthesis and starch metabolism in citrus.
  • Knocking out of DUO1 in Hong Kong kumquat (Fortunella hindsii) resulted in small and seedless fruit phenotypes.
  • Through additional cross-pollination experiments,DUO1 was proven to be the key target gene for miR159a to regulate male sterility in citrus.
  • The miR159a-DUO1 module reduced the expression of the starch synthesis gene SS4 and sugar transport gene STP8 to disrupt starch metabolism in pollen.
  • Overall, this work reveals a new mechanism by which the miR159a-DUO1 module regulates pollen development and elucidates the molecular regulatory network underlying male sterility in citrus.
