Different ecological affinities and aggressiveness patterns among Didymella rabiei isolates from sympatric domesticated chickpea and wild Cicer judaicum.
Domesticated chickpea (Cicer arietinum) and its wild relative C. judaicum grow in sympatric distribution in Israel and both are susceptible to Ascochyta blight caused by Didymella rabiei. C. arietinum was grown for millennia in drier and hotter Levantine spring conditions while C. judaicum grows in the wetter and milder winters. Accordingly, it is possible that D. rabiei isolates originated fro...
متن کاملSympatric ascochyta complex of wild Cicer judaicum and domesticated chickpea
The aim of this study was to isolate, identify and characterize ascochyta blight pathogens from Cicer judaicum , a wild annual Cicer species which grows in Israel and other Mediterranean countries in sympatric distribution with legume crops, and determine their virulence and aggressiveness to other wild and domesticated legumes. Native C. judaicum plants exhibited symptoms resembling ascochyta ...
متن کاملEcological genetic divergence of the fungal pathogen Didymella rabiei on sympatric wild and domesticated Cicer spp. (Chickpea).
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...
متن کاملEffects of Temperature Stresses on the Resistance of Chickpea Genotypes and Aggressiveness of Didymella rabiei Isolates
Chickpea (Cicer arietinum L.) is an important food and rotation crop in many parts of the world. Cold (freezing and chilling temperatures) and Ascochyta blight (Didymella rabiei) are the major constraints in chickpea production. The effects of temperature stresses on chickpea susceptibility and pathogen aggressiveness are not well documented in the Cicer-Didymella pathosystem. Two experiments w...
متن کاملEcogeography and Demography of Cicer judaicum Boiss., a Wild Annual Relative of Domesticated Chickpea
Chickpea (Cicer arietinum L.) is a major pulse crop in the Indian subcontinent and other world regions and is characterized by narrow adaptation relative to other cool season food legumes. Comparative ecophysiology employing closely related wild species is a powerful tool to broaden the understanding of the genetic and physiological basis of crop adaptation. However, meager data are available o...
