High-density cDNA microarrays (2,027 unigenes) were used to analyze transcript profiles of the plant-pathogenic fungus Blumeria graminis f.sp.hordei throughout its asexual life cycle and development of infection.RNA was obtained from four stages preceding penetration and four stages after penetration of the host cells.The microarray data was valida

Diapause intensity (DI) is a physiological lip tint trait represented by the duration of diapause under given conditions of environment.In many species, it is highly variable, probably being controlled by multiple genes and tends to form a cline in response to the latitudinal gradient of selection pressure.DI clines could be established artificiall

The potential of fluorescent Pseudomonas spp.to control Alternaria leaf spot on Sockets castorbean, caused by Alternaria ricini, was studied under greenhouse conditions.Two periods for antagonist applications were tested: 48h before and simultaneously to the pathogen inoculation.Among the antagonists tested JA4 and BJ22 were the most effectives sho
