The Detection and Characterization of QoI-Resistant Didymella rabiei Causing Ascochyta Blight of Chickpea in Montana
Ascochyta blight (AB) of pulse crops (chickpea, field pea, and lentils) causes yield loss in Montana, where 1.2 million acres was planted to pulses in 2016. Pyraclostrobin and azoxystrobin, quinone outside inhibitor (QoI) fungicides, have been the choice of farmers for the management of AB in pulses. However, a G143A mutation in the cytochrome b gene has been reported to confer resistance to Qo...
متن کاملrabiei, the causal agent of Ascochyta blight of chickpea (Cicer arietinum L.), and toxin production-by the wild type
Ascochyta rabiei is the causal agent of blight of chickpea, an important food legume crop for human populations in Developing Countries. All reliably identified isolates of the fungus produce toxins in culture, known as the solanapyrones, of which solanapyrone A is the most frequently found and also the most toxic. The principal aim of the project was to determine the role of this toxin in the ...
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...
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...
