Molecular responses of Phytophthora capsici-challenged cucumber (Cucumis sativus L.) plants as influenced by resistance inducer application
Phytophthora species are considered as the major cause of several plant diseases resulting in huge yield losses in agricultural crops. Despite years of effort to develop Phytophthora resistance varieties, there is no reports of a resistant cucumber variety. In this study, the effect of concomitant application of potassium phosphite (KPhi) and chitosan on some physiological and molecular respons...
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...
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 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 کاملInfluence of environmental factors on Cucumis melo L. var. agrestis Naud. seed germination and seedling emergence
Cucumis melo L. var. agrestis Naud. (field muskmelon) is an annual invasive weed in many parts of Asia. However, there is very little available information about the germination and emergence of this species. Therefore, laboratory experiments were conducted to evaluate the effects of light, temperature, salt stress, osmotic stress, pH, and depth of planting on field muskmelon germination and se...
