چکیده

Nas regiões Centro-Oeste e Sul do Brasil, a cultura da erva-mate (Ilex paraguariensis) constitui-se uma importante fonte de extrativismo florestal, além diversificar renda, principalmente na agricultura familiar. A erva-mate, como outras espécies florestais, é infectada por diversos patógenos, o gênero Fusarium, causador podridão-de-raízes. Os patógenos possuem ampla variabilidade genética, mesmo dentro um único única espécie, resultado adaptações ao meio em que vivem. Este estudo teve objetivo avaliar sequenciamento das genoma ITS β-tubulina identificação nível espécie dos isolados Fusarium spp. patogênicos à identificar formação grupos compatibilidade vegetativa (VCG) entre os erva-mate. O consolidou separação sete F. solani oxysporum. Para esses isolados, técnica para obtenção mutantes nit foi adequada classificação fenotípica, fundamentais nos testes VCG sendo obtidos cinco VCG.

Morphological and molecular characterization of Fusarium spp pathogenic to pecan tree in Brazil.

The occurrence of Fusarium spp associated with pecan tree (Carya illinoinensis) diseases in Brazil has been observed in recent laboratory analyses in Rio Grande do Sul State. Thus, in this study, we i) obtained Fusarium isolates from plants with disease symptoms; ii) tested the pathogenicity of these Fusarium isolates to pecan; iii) characterized and grouped Fusarium isolates that were pathogen...

Vegetative compatibility and rep-PCR DNA fingerprinting groups of Fusarium solani isolates obtained from different hosts and their pathogenicity

Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...

Pathogenicity and Diversity of Vegetative Compatibility of Fusarium Verticillioides

Pathogenicity of 10 Fusarium verticillioides isolates, originated from grain of wheat (five isolates) and maize (five isolates), were studied under greenhouse conditions. Based on different parameters of the pathogenicity estimate (a scale for % of nonemerged plants, % of survived plants, plant vigour — the growth and dry weight of roots and epicotyls and disease severity) it was determined tha...

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 ...
