Gene Details:

  • Gene ID:
  • Gene Symbol: GhVIN1
  • Gene Name: vacuolar invertase1
  • Genome: TM1_NBI
  • Species: Gossypium hirsutum

Functional Descriptions:

  • Silencing the vacuolar invertase gene GhVIN1 blocks cotton fiber initiation from the ovule epidermis, probably by suppressing a cohort of regulatory genes via sugar signaling.
  • RNAi-mediated suppression of GhVIN1, a major VIN gene that is highly expressed in wild-type fiber initials, resulted in significant reduction of VIN activity and consequently a fiberless seed phenotype in a dosage dependent manner.
  • Gene expression analyses coupled with in vitro ovule culture experiments revealed that GhVIN1-derived hexose signaling may play an indispensable role in cotton fiber initiation, probably by regulating the transcription of several MYB transcription factors and auxin signaling components that were previously identified as required for fiber initiation.
  • GhVIN1-silenced transgenic cotton plants exhibited a fiberless seed phenotype due to reduction of VIN activity in the ovule epidermis.
