Expression of a metacaspase gene of Nicotiana benthamiana after inoculation with Colletotrichum destructivum or Pseudomonas syringae pv. tomato, and the effect of silencing the gene on the host response

Abstract

Metacaspases are cysteine proteinases that have homology to caspases, which play a central role in signaling and executing programmed cell death in animals. A type II metacaspase cDNA, NbMCA1, was amplified from Nicotiana benthamiana infected with Colletotrichum destructivum. It showed a peak in expression at 72 h post-inoculation corresponding with the… (More)
