Gene Details:

  • Gene ID:
  • Gene Symbol: CsKPI3
  • Gene Name: Kunitz protease inhibitor 3
  • Genome:
  • Species: Camellia sinensis

Functional Descriptions:

  • The overall findings suggest that the transcriptional divergence of KPI genes after duplication led to the specialized role of CsKPI1 in the physiological response to insect stress; the functional conservation between CsKPI2 and CsKPI3 confers resistance to pathogen infection in tea plant.
  • We showed that salicylic acid (SA) and transcripts of CsKPI2 and CsKPI3 significantly accumulated after infection with Glomerella cingulata. The application of exogenous SA stimulated the high expression of both CsKPI2 and CsKPI3 by activating cis-elements within their promoters.
  • Specifically, the expression of CsKPI2 and CsKPI3 reached peaks of up to 26.5-fold and 7.6-fold higher than those of the control at 10 days post inoculation, respectively; however, CsKPI1 was only 1.1-fold expression at 10 days post inoculation, suggesting the functional diversity among them in response to pathogen infection.
  • The results showed that CsKPI2p - and CsKPI3p-driven GFP were strongly expressed in SA-treated protoplast cells but not in untreated cells.
  • The functional conservation between CsKPI2 and CsKPI3 confers resistance to pathogen infection in tea plant.
