Differential activation of defense-related genes in susceptible and resistant pepper cultivars infected with Phytophthora capsici.
This study investigated the expression pattern of genes encoding for a basic PR-1 protein, a basic beta-1,3-glucanase, a peroxidase, and a sesquiterpene cyclase involved in defense responses in three pepper cultivars with different levels of resistance to Phytophthora capsici. All genes were up-regulated in infected stems of the pepper cultivars, with expression being detected 8h post-inoculati...
متن کاملSelection of genetically diverse Trichoderma spp. isolates for suppression of Phytophthora capsici on bell pepper.
Environmentally compatible control measures are needed for suppression of Phytophthora capsici on pepper. Twenty-three isolates of Trichoderma were screened for suppression of a mixture of 4 genetically distinct isolates of this pathogen on bell pepper (Capsicum anuum) in greenhouse pot assays. Of these 23 isolates, GL12, GL13, and Th23 provided significant suppression of P. capsici in at least...
متن کاملPhytophthora capsici Epidemic Dispersion on Commercial Pepper Fields in Aguascalientes, Mexico
Chili pepper blight observed on pepper farms from north Aguascalientes was monitored for the presence of Phytophthora capsici during 2008-2010. Initially, ELISA tests were directed to plant samples from greenhouses and rustic nurseries, showing an 86% of positive samples. Later, samples of wilted plants from the farms during the first survey were tested with ELISA. The subsequent survey on soil...
متن کاملGenetic determinants of the defense response of resistant and susceptible pepper (Capsicum annuum) cultivars infected with Phytophthora capsici (Oomycetes; Pythiaceae).
Based on culture isolation and morphological observation blight-infected pepper plants in Shaanxi Province, China, we identified the pathogen causing pepper phytophthora blight as Phytophthora capsici. Varieties that differed in resistance (CM334, PBC602, and B27) were inoculated with this pathogen. The root activity of resistant CM334 variety was the highest while that of susceptible B27 varie...
متن کاملBiocontrol of Phytophthora Blight and Anthracnose in Pepper by Sequentially Selected Antagonistic Rhizobacteria against Phytophthora capsici
We previously developed a sequential screening procedure to select antagonistic bacterial strains against Phytophthora capsici in pepper plants. In this study, we used a modified screening procedure to select effective biocontrol strains against P. capsici; we evaluated the effect of selected strains on Phytophthora blight and anthracnose occurrence and fruit yield in pepper plants under field ...
