Gene Details:

  • Gene ID:
  • Gene Symbol: CsKPI1
  • Gene Name: Kunitz protease inhibitor 1
  • Genome:
  • Species: Camellia sinensis

Functional Descriptions:

  • Under Ectropis oblique attack, CsKPI1 expression and jasmonic acid (JA) levels were more abundant in both insect-damaged leaf tissues and undamaged neighboring leaves.
  • The application of jasmonic acid methyl ester elicited high expression levels of CsKPI1, suggesting that CsKPI1 accumulation requires JA production in tea plant.
  • These results suggest that the CsKPI1 gene may play a role in signal transduction in the tea plant response to tea geometrid attack.
  • 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.
  • 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.
