Heat and disease: the genetic tug-of-war in pepper immunity
Chinese Academy of SciencesA recent study has discovered that SALT TOLERANCE HOMOLOG2 (CaSTH2), a gene in pepper, acts as a negative regulator of the plant’s defense mechanisms. This gene impairs the activation of immune responses against Ralstonia solanacearum infection (RSI) and reduces heat tolerance by interacting with and inhibiting CaWRKY40, a key transcription factor in these processes.
