Genetics of resistance to powdery mildew (Microsphaera diffusa) in Brazilian soybean populations

Crosses between resistant and susceptible soybean cultivars were performed and the F2 populations were obtained to study the inheritance of soybean resistance to powdery mildew and to estimate the number and action of genes related to resistance. The reaction to powdery mildew was studied in a greenhouse and pots carrying plants with symptoms were distributed among the pots carrying the genotyp...

Spore Germination, Infection Structure Formation, and Colony Development of Erysiphe pulchra on Dogwood Leaves and Glass Slides

Flowering dogwood (Cornus florida L.) is used as an important ornamental tree in North America, Japan, and Europe. Since 1995, epidemics of powdery mildew caused by Erysiphe pulchra (Cooke and Peck) U. Braun & S. Takamatsu (syn. Microsphaera pulchra Cooke and Peck) have impeded production of flowering dogwood throughout much of the eastern United States. The fungus is an obligate parasite and g...

Effects of powdery mildew infection on chloroplast and mitochondrial functions in rubber tree

Powdery mildew (Oidium heveae Steinm.) is one of the most important leaf diseases in rubber tree (Hevea brasiliensis). However, physiological and molecular processes associated with the Hevea-powdery mildew interaction are still unclear. In this study, effects of powdery mildew infection on the mitochondrial and chloroplast functions in rubber tree were comprehensively investigated. Powdery mil...
