Abstract:
... Ascochyta blight, caused by Ascochyta lentis Vassilievsky, is an important fungal disease of lentil (Lens culinaris subsp. culinaris). Manifestation of disease in plants is due to differential expression of genes in the both host and the pathogen. Identification of genes that are differentially expressed in varieties with resistance to A. lentis will lead to the accurate selection and development ...

In 2004-2005, application of non-amended suspensions of Aureobasidium pullulans conidia to post-harvest chickpea debris resulted in 37.9% fewer Ascochyta blight lesions on chickpea test plants relative to controls. Analogous tests in 2006-2007 resulted in 38.4% fewer lesions. Ascospores released from debris were predominantly Davidiella sp. (anamorph, Cladosporium sp.), followed by Didymella rabi ...

Use of these QTL to improve crop species, however, is hindered because the genes contributing to the trait are not known. Five disease resistance QTL that colocalized with defense response genes were accumulated by marker-aided selection to develop ...

It is generally known that a form of duplication can generate new genes, suggesting that a new gene usually evolves from an ancestral gene. However, we show that a new defense gene in plants may evolve by de novo origination, resulting in sophisticated disease-resistant functi ...
