Abstract
Ethylene-responsive factors play important roles in the biotic and abiotic stresses. Only some ERF genes from Capsicum annuum have been characterized. In the study, the CaERF1A gene is characterized in response to biotic stress. CaERF1A transcripts were induced by various plant defense-related hormone treatments. Knockdown of CaERF1A in hot pepper plants are negatively affected Tobacco mosaic virus-P0-mediated hypersensitive response cell death, resulting in reduced gene expression of pathogenesis-related genes and ethylene and jasmonic acid synthesis-related gene. Overexpressing CaERF1A transgenic plants show enhanced resistance to fungal pathogen via regulating ethylene and jasmonic acid synthesis-related gene expression. Thus, CaERF1A is a positive regulator of plant defense by modulating ethylene and jasmonic acid synthesis-related gene expressions.
