Fruit Yield, Quality Variables, and Powdery Mildew Susceptibility of Galia Melon Cultivars Grown in a Passively Ventilated Greenhouse

Galia muskmelon (Cucumis melo L. var. Reticulatus Ser.) is an F1 hybrid known for exceptional fruit flavor. Since introduction to the market in 1973, the original ‘Galia’ has become a trade name for look-alike cultivars. Some ‘Galia’-type cultivars are firmer, ship well, and may be less susceptible to powdery mildew [Podosphaera xanthii (Px) (syn. Sphaerotheca fulignea)] than a true ‘Galia’, bu...

Correlation of defense gene induction defects with powdery mildew susceptibility in Arabidopsis enhanced disease susceptibility mutants.

We investigated the relative importance of specific Arabidopsis thaliana genes in conferring resistance to bacterial versus fungal pathogens. We first developed a pathosystem involving the infection of Arabidopsis accession Columbia with a virulent isolate of the obligate biotrophic fungal pathogen Erysiphe orontii. E. orontii elicited the accumulation of mRNAs corresponding to the defense-rela...

Susceptibility of Catalpa, Chilopsis, and Hybrids to Powdery Mildew and Catalpa Sphinx Larvae

A diverse collection of germplasm representing 24 taxa from Catalpa sect. Catalpa Paclt and sect.MacrocatalpaGrisebach, Chilopsis D. Don, and ·Chitalpa Elias & Wisura were screened for susceptibility to powdery mildew (PM) incited by Erysiphe elevata (Burr.) U. Braun & S. Takam and feeding by catalpa sphinx larvae (CSL), Ceratomia catalpae (Boisduval). PM screening was conducted on plants grown...
