Resistance of pepper germplasm to Phytophthora capsici isolates collected in northwest Spain
One single pathotype (race 0) was identified among eight tested isolates of Phytophthora capsici (Leonian) collected in northwest Spain, after inoculation tests using pepper cultivars of different origin, including the well known reference resistant cultivar Serrano Criollo de Morelos 334. Complete resistance to P. capsici was not found after the inoculation of 23 local genotypes of Capsicum an...
متن کاملBABA and Phytophthora nicotianae Induce Resistance to Phytophthora capsici in Chile Pepper (Capsicum annuum)
Induced resistance in plants is a systemic response to certain microorganisms or chemicals that enhances basal defense responses during subsequent plant infection by pathogens. Inoculation of chile pepper with zoospores of non-host Phytophthora nicotianae or the chemical elicitor beta-aminobutyric acid (BABA) significantly inhibited foliar blight caused by Phytophthora capsici. Tissue extract a...
متن کاملDifferential 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 کاملGenetic diversity of Phytophthora capsici isolates from pepper and pumpkin in Argentina.
Phytophthora capsici is a soilborne oomycete plant pathogen that limits pepper production worldwide. The population structure varies significantly depending on the location (e.g. Peru vs. USA) and little is known about the diversity of P. capsici in Argentina. Our objective was to assess the diversity of P. capsici in Argentina at key pepper production areas. Forty isolates were recovered 2006-...
