Anti-oxidative enzyme changes associated with chickpea calli tolerant to Ascochyta rabiei culture filtrate.
Ascochyta blight caused by Ascochyta rabiei (Pass.) Labrousse is a major biotic constraint in production of chickpea. In the present investigation, all chickpea genotypes [E100Y (m), Gaurav, Pb-7 and L550] induced 100% callus on standard medium with greenish colour and fragile structure. These calli were used for in vitro screening against pathogen, A. rabiei culture filtrate at 0, 5, 10, 15 an...
متن کاملComparative Transcriptome Analysis of the Necrotrophic Fungus Ascochyta rabiei during Oxidative Stress: Insight for Fungal Survival in the Host Plant
Localized cell death, known as the hypersensitive response (HR), is an important defense mechanism for neutralizing phytopathogens. The hallmark of the HR is an oxidative burst produced by the host plant. We aimed to identify genes of the necrotrophic chickpea blight fungus Ascochyta rabiei that are involved in counteracting oxidative stress. A subtractive cDNA library was constructed after men...
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 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...
متن کاملMating Type Groups of Ascochyta rabiei (Teleomorph: Didymella rabiei), the Causal Agent of Chickpea Blight in Central Anatolia
The distribution of mating types of Ascochyta rabiei (teleomorph: Didymella rabiei) was studied on isolates collected from chickpea growing areas of Central Anatolia. Mating type assessments of 45 isolates from 6 different provinces were conducted under laboratory conditions. After keeping for 5-6 weeks, the pseudothecial development and ascospore production were observed on chickpea stem piece...
