fusarium wilt of melon is a destructive fungal disease throughout the world. in this study, the evolutionary relationships among isolates of different formae speciales of fusarium oxysporum was examined, with a special emphasis on the forma specialis melonis. bootstrapped maximum likelihood analysis of the elongation factor-1α (ef-1α) sequence was conducted on 16 iranian and 11 foreign isolates...

ABSTRACT Cryphonectria cubensis is the causal agent of a serious canker disease of Eucalyptus spp. in tropical and subtropical parts of the world. In this study, a South African C. cubensis isolate was transfected by electroporation with a synthetic RNA transcript corresponding to the full-length coding strand of the C. parasitica hypovirus (CHV1-EP713). Hypovirus infection resulted in pronounc...

The fungal phylum Ascomycota comprises a large proportion of species with no known sexual stage, despite high genetic variability in field populations. One such asexual species, Aspergillus parasiticus, is a potent producer of carcinogenic and hepatotoxic aflatoxins, polyketide-derived secondary metabolites that contaminate a wide variety of agricultural crops. In this study, individuals of A. ...

Head cabbage androgenic genotypes of R1 and R2 generations derived from Jaguar F1 donor hybrid were evaluated according to their agroeconomical characters, ability for generative propagation, self-incompatibility, intraline uniformity and stability of morphological characters. Most of R1 and R2 genotypes had desired morphological characters. However, in R1 generation 21 lines showed lack of int...
