We have assessed the distribution and mating type of chickpea blight (Didymella rabiei (Kov.) v. Arx) from a total 350 272 fields in major (Cicer arietinum L.) growing areas Ethiopia for two consecutive cropping seasons 2017 2018, respectively. The prevalence D. was 20 % year 7% 2018. Severity range 2?9 incidence 10–100 were recorded both only 7–20 assed fields. Field 2018 significantly differe...
Crude protein extracts from the chickpea (Cicer arietinum L .) pathogenic fungus Ascochyta rabiei catalyze the N A D PH dependent conversion of the pterocarpan phytoalexins medicarpin and maackiain to 1) 2'-hydroxyisoflavans, 2) 1 a-hydroxypterocarp-l,4-diene-3-one, and 3) 10,2'dihydroxyisoflav-8-ene-7-one derivatives. A pterocarpan: N A D PH oxidoreductase which cleaves the benzylphenyl ether ...
For millennia, chickpea (Cicer arietinum) has been grown in the Levant sympatrically with wild Cicer species. Chickpea is traditionally spring-sown, while its wild relatives germinate in the autumn and develop in the winter. It has been hypothesized that the human-directed shift of domesticated chickpea to summer production was an attempt to escape the devastating Ascochyta disease caused by Di...
Plant diseases are caused by pathogen populations continuously subjected to evolutionary forces (genetic flow, selection, and recombination). Ascochyta blight, caused by Mycosphaerella pinodes, is one of the most damaging necrotrophic pathogens of field peas worldwide. In France, both winter and spring peas are cultivated. Although these crops overlap by about 4 months (March to June), primary ...
