Antifungal activity of n-hexane extracts of Datura metel against Ascochyta rabiei
The antimycotic potential of Datura metel (syn. Datura alba Nees.) was investigated in vitro against Ascochyta rabiei, the cause of chickpea blight disease. The pathogen was exposed to various n-hexane concentrations (1, 2, 3 and 4% w/v) of shoot and root extracts of D. metel using poisoning food technique. All the employed concentrations of both root and shoot extracts significantly suppressed...
متن کاملAccumulation and Biosynthesis of Solanapyrone Phytotoxins by Ascochyta rabiei
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...
متن کاملExpansion of Chenopodium Album Leaf Disks as Affected by Coumarin.
Although leaf expansion is obviously a fundamental process in the development of plants, its physiological mechanism is little understood, and has been but sparingly investigated. It is known that auxins affect the elongation of the leaf veins (1) but do not seem to influence the expansion of the laminar leaf tissues. BONNER et al. (3) observed an increase in expansion of radish leaf disks floa...
متن کاملContinental Diversity of Chenopodium album Seedling Recruitment
Chenopodium album seedling emergence studies were conducted at nine European and two North American locations comparing local populations with a common population from Denmark (DEN-COM). Mortality risk. Weedy plant life history conforms to the time of mortality risk from either the environment (e.g. frozen soil in the winter) or cropping systems practices (e.g. herbicide use). C. album life his...
متن کاملCharacterization and cloning of cutinase from Ascochyta rabiei.
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...
