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...

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...

ascochyta rabiei is one of the devastaining fungi pathogens of chick-pea (cicer arietinum l.) crops. in the present investigation, forty-two iranian isolates of ascochyta rabiei fungi (including highly, weakly and moderate virulent isolates), whose pathogenisities were determined previously, were studied. polygalacturonase is a main factor in the initiation of ascochyta blight disease. therefor...

Nohut antraknoz hastalığına karşı yaygın kullanılan Nativo®, Bellis®, Altis® Premier, Thiovit Jet®, Pomarsol Forte®, Dikotan ®M45, ®M22 adlı fungisitlerin in vitro koşullarda Ascochyta rabiei’nin dokuz (9) izolatına direnç durumunun yanı sıra A. rabiei ile doğal enfekteli nohut tohumlarının çimlenme ve hastalık çıkışları üzerine etkisi iklim odasında vivo araştırılmıştır. Fungisitlere YBUAr1, Y...

Old Yellow Enzyme (OYE1) was the first flavin-dependent enzyme identified and characterized in detail by the entire range of physical techniques. Irrespective of this scrutiny, true physiological role of the enzyme remains a mystery. In a recent study, we systematically identified OYE proteins from various fungi and classified them into three classes viz. Class I, II and III. However, there is ...

the fungal disease, ascochyta blight, caused by ascochyta rabiei is a major yield limiting factor of chickpea (cicer arietinum l.) in many countries, including iran. identification of resistance sources against races or pathotypes of the fungus causing this disease is required for breeding resistant chickpea cultivars. reaction of six selected genotypes of iranian chickpea collection was evalua...
