Local 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 کاملIdentification of pathogenicity‐related genes in Fusarium oxysporum f. sp. cepae
Pathogenic isolates of Fusarium oxysporum, distinguished as formae speciales (f. spp.) on the basis of their host specificity, cause crown rots, root rots and vascular wilts on many important crops worldwide. Fusarium oxysporum f. sp. cepae (FOC) is particularly problematic to onion growers worldwide and is increasing in prevalence in the UK. We characterized 31 F. oxysporum isolates collected ...
متن کاملgenetic 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 کاملRegulation of miR394 in Response to Fusarium oxysporum f. sp. cepae (FOC) Infection in Garlic (Allium sativum L)
MicroRNAs (miRNAs) are a class of post-transcriptional regulators that negatively regulate gene expression through target mRNA cleavage or translational inhibition and play important roles in plant development and stress response. In the present study, six conserved miRNAs from garlic (Allium sativum L.) were analyzed to identify differentially expressed miRNAs in response to Fusarium oxysporum...
متن کاملTHE SENSITIVITY OF ASPERGILLUS NIGER AND FUSARIUM OXYSPORUM f . sp . CEPAE TO FUNGISTASIS IN ONION - GROWING SOILS
Twenty-seven soil samples were collected from the onion (Allium cepa L.) fields of Tekirdag province, Turkey. These samples were investigated for the sensitivity of Aspergillus niger V. Tieghem (AN) and Fusarium oxysporum Schlechtend.: Fr. f. sp. cepae (H. N. Hans.) W. C. Snyder H. N. Hans (FOC), known as the causal agents of black mould and basal rot of onion, respectively, to soil fungistasis...
