rabiei, 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 کاملBiochemical and molecular biological studies on infection (Ascochyta rabiei)-induced thaumatin-like proteins from chickpea plants (Cicer arietinum L.).
A pathogenesis-related protein induced by infection with Ascochyta rabiei was purified from intercellular washing fluid of chickpea (Cicer arietinum L.) leaves. Amino-terminal sequencing identified the protein, named PR-5a, as a thaumatin-like protein. The isoelectric point was determined with 6.5 and the molecular mass is 16 kDa. Therefore, chickpea PR-5a is the first dicot member of a TLP sub...
متن کاملFungi Resident in Chickpea Debris and their Suppression of Growth and Reproduction of Didymella rabiei under Laboratory Conditions
Fungi colonizing senescent chickpea (Cicer arietinum) stems and postharvest debris from Pullman, WA, were enumerated and identified with the objective of finding species potentially useful for biological control of Didymella rabiei (conidial state 1⁄4 Ascochyta rabiei), causal agent of Ascochyta blight. In addition to D. rabiei, primary colonizers were, in order of decreasing abundance, Alterna...
متن کاملThe 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 کاملIsolation of Biocontrol (Bacterial) Agents from Chickpea (Cicer arietinum linnaeus)
Gram or Chickpea (Cicer arietinum Linnaeus), a member of family Fabaceae, is an ancient leguminous crop which is self pollinated, diploid annual (2N=16 chromosomes) grown since 7000BC, in different area of the world but major cultivation is concentrated in semi-arid environments of different areas of the world. It is ranked 3 rd after common bean (Phaseolus vulgaris L.) and pea (Pisum sativum) ...
