genetic relationship among fusarium oxysporum f. sp. melonis vegetative compatibility groups and their relatedness to other f. oxysporum formae speciales
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...
متن کاملLocal origin of two vegetative compatibility groups of Fusarium oxysporum f. sp. vasinfectum in Australia
Pathogenicity and genetic diversity of Fusarium oxysporum from geographically widespread native Gossypium populations, including a cotton growing area believed to be the center of origin of VCG 01111 and VCG 01112 of F. oxysporum f. sp. vasinfectum (Fov) in Australia, was determined using glasshouse bioassays and AFLPs. Five lineages (A-E) were identified among 856 isolates. Of these, 12% were ...
متن کاملTranscriptome Analysis of the Melon-Fusarium oxysporum f. sp. melonis Race 1.2 Pathosystem in Susceptible and Resistant Plants
Fusarium oxysporum f. sp. melonis Snyd. & Hans race 1.2 (FOM1.2) is the most virulent and yield-limiting pathogen of melon (Cucumis melo L.) worldwide. Current information suggest that the resistance to race 1.2 is controlled by multiple recessive genes and strongly affected by the environment. RNA-Seq analysis was used to identify candidate resistance genes and to dissect the early molecular p...

متن کاملRecovery of Mutants Impaired in Pathogenicity After Transposition of Impala in Fusarium oxysporum f. sp. melonis.
ABSTRACT The ability of transposon impala to inactivate genes involved in pathogenicity was tested in Fusarium oxysporum f. sp. melonis. Somatic excision of an impala copy inserted in the nitrate reductase-encoding niaD gene was positively selected through a phenotypic assay based on the restoration of nitrate reductase activity. Independent excision events were analyzed molecularly and shown t...
