Expression of Hydroxymethylglutaryl-CoA Reductase 2 (HMG2) Gene in Chilli (Capsicum annuum L.) CM334 Infected by Nacobbus aberrans and Phytophthora capsici

  Plants of chilli Capsicum annuum L. CM334 show a high level of resistance to Phytophthora capsici, but are susceptible to Nacobbus aberrans; such resistance has been associated with capsidiol accumulation, a sesquiterpene phytoalexin. In the present study the expression of...
