Phytophthora capsici Zoospore Infection of Pepper Fruit in Various Physical Environments
Phytophthora capsici is a pathogen on several economically important crops including pepper. The fungus attacks the roots, stems, leaves and fruit of the plant. Experiments were conducted to determine environmental conditions that may affect infection of pepper fruit by zoospores of P. capsici. Two techniques were used to inoculate the mature green pepper fruit. First, the blossom end of the fr...
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 کاملResistance 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 کاملEvaluation of Watermelon Germplasm for Resistance to Phytophthora Blight Caused by Phytophthora capsici
This study was conducted to determine the Phytophthora rot resistance of 514 accessions of watermelon germplasm, Citrullus lanatus var lanatus. About 46% of the 514 accessions tested were collections from Uzbekistan, Turkey, China, U.S.A., and Ukraine. Phytophthora capsici was inoculated to 45-day-old watermelon seedlings by drenching with 5 ml of sporangial suspension (10(6) sporangia/ml). At ...
متن کاملExocarp Properties and Transcriptomic Analysis of Cucumber (Cucumis sativus) Fruit Expressing Age-Related Resistance to Phytophthora capsici
Very young cucumber (Cucumis sativus) fruit are highly susceptible to infection by the oomycete pathogen, Phytophthora capsici. As the fruit complete exponential growth, at approximately 10-12 days post pollination (dpp), they transition to resistance. The development of age-related resistance (ARR) is increasingly recognized as an important defense against pathogens, however, underlying mechan...
