Studies were undertaken across five field locations in Western Australia to determine the relative changes disease severity and subsequent pea yield from up four foliar pathogens associated with a complex (viz. genera Didymella, Phoma, Peronospora, Septoria) different varieties sown at three times densities. Delaying sowing of significantly (P < 0.05) reduced Ascochyta blight (all locations)...
The biosynthesis of the phytotoxins solanapyrone A , B and C produced by the phytopathogenic fungus Ascochyta rabiei has been investigated. To optimize feeding conditons for the tracer experiments the growth of the fungus and the accumulation of the toxins in submers culture were determined. The accumulation kinetics revealed that formation of the toxins occurs in the stationary phase of the gr...
Ascochyta rabiei, the causal agent of Ascochyta blight on chickpea plants, secretes a cutinase in the culture filtrate when it is induced by cutin or hydroxylated fatty acids. This cutinase is the main esterase in the culture fluids. The enzyme was purified to homogeneity by three successive chromatographic steps. It showed an apparent molecular weight of 22 kD in SDS-PAGE and cleaved ester bon...
