Host-Pathogen Interactions: XV. Fungal Glucans Which Elicit Phytoalexin Accumulation in Soybean Also Elicit the Accumulation of Phytoalexins in Other Plants.
A beta-glucan isolated from the mycelial walls of Phytophthora megasperma var. sojae and a glucan purified from yeast extract stimulate the accumulation of phytoalexins in red kidney bean, Phaseolus vulgaris, and stimulate the accumulation of the phytoalexin, rishitin, in potato tubers, Solanum tuberosum. These glucans have previously been shown to be potent elicitors of glyceollin accumulation...
متن کاملGenetic Diversity of Phytophthora Sojae in Iran
Objective: The aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of P. sojae from Iran. Methods: During 2005–2007, 142 isolates of Phytophthora sojae were collected from soil samples and diseased soybean plants from Lorestan, Mazandaran, Golestan and Ardabil provinces. Races of the isolates were determined. DNA of P. sojae...
متن کاملRNA interference of soybean isoflavone synthase genes leads to silencing in tissues distal to the transformation site and to enhanced susceptibility to Phytophthora sojae.
Isoflavones are thought to play diverse roles in plant-microbe interactions and are also potentially important to human nutrition and medicine. Isoflavone synthase (IFS) is a key enzyme for the formation of the isoflavones. Here, we examined the consequences of RNAi silencing of genes for this enzyme in soybean (Glycine max). Soybean cotyledon tissues were transformed with Agrobacterium rhizoge...

متن کاملHost-Pathogen Interactions: IX. Quantitative Assays of Elicitor Activity and Characterization of the Elicitor Present in the Extracellular Medium of Cultures of Phytophthora megasperma var. sojae.
Resistance of soybean (Glycine max L.) seedlings to Phytophthora megasperma var. sojae (Pms) is in part due to the accumulation in infected tissue of a compound which is toxic to Pms. The accumulation of this compound, a phytoalexin called glyceollin, is triggered by infection, but it can also be triggered by molecules, "elicitors," present in cultures of Pms. The ability of the Pms elicitor to...
