Gene Details:

  • Gene ID: Ghir_D02G025140
  • Gene Symbol: GhNSP
  • Gene Name: NO SPINE POLLEN
  • Genome: TM1_NBI
  • Species: Gossypium hirsutum

Functional Descriptions:

  • Degradation of de-esterified pctin/homogalacturonan by the polygalacturonase GhNSP is necessary for pollen exine formation and male fertility in cotton.
  • GhNSP encodes a polygalacturonase protein homologous to AtQRT3, which suggests a function for polygalacturonase in pollen exine formation.
  • Immunofluorescence studies using antibodies to the de-esterified and esterified homogalacturonan (JIM5 and JIM7) showed that the GhNSP mutant exhibits abundant of de-esterified homogalacturonan in the tapetum and exine, coupled with defective exine formation.
  • The characterization of GhNSP provides new understanding of the role of polygalacturonase and de-esterified homogalacturonan in pollen exine formation.
