Fusarium oxysporum is a soil-born fungus that induces wilt and root rot on a variety of plants. F. oxysporum f. sp. conglutinans (Foc) can cause wilt disease on cabbage. This study showed that a homolog of SIX1 protein in the Arabidopsis infecting isolate Fo5176 (Fo5176-SIX1) had four isoforms in the conidia of Foc by proteomic analysis. Thus, we analyzed the roles of protein Foc-SIX1. Gene exp...

Ditylenchus dipsaci and Fusarium oxysporum f. sp. medicaginis synergistically affected the mortality and plant growth of Ranger alfalfa, a cultivar susceptible to stem nematode and Fusarium wilt. The nematode-fungus relationship had an additive effect on mortality and plant growth of Lahontan (nematode resistant and Fusarium wilt susceptible) and of Moapa 69 (nematode susceptible and Fusarium w...

Wilt and crown rot of sweet basil (Ocimum basilicum), caused by Fusarium oxysporum f. sp. basilici, represents a major problem on this crop, which is grown in Italy over a large area (approximately 80 ha) under glasshouse, mainly in the Riviera Ligure (5). First reported in Russia (12), F. oxysporum f. sp. basilici has been observed in Italy (6,22), France (15), the United States (1,2,7,24), an...

Strains of Pseudomonas putida, Pseudomonas sp., and Pseudomonas aeruginosa were examined for their ability to grow in the presence of the iron chelator, ethylenediamine-di-(o-hydroxyphenylacetic acid). In vitro fungal inhibition assays showed that the isolates varied in their ability to inhibit the growth of representative fungal plant pathogens. Fungal inhibition in vitro was superior to that ...

Few commercial genotypes of tomato are resistant to Fusarium wilt (Fusarium oxysporum f. sp. lycopersici [FOL]), especially race 3. We developed five intraspecific hybrids Solanum lycopersicum (FOX1 FOX5) and assessed them for agronomic traits resistance FOL races 1, 2, 3, a mixture these races. FOX1 FOX4 were all the but did not have desired traits. Next, as rootstocks cherry Sweet Heaven. The...

Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceris can be managed by risk assessment and use of resistant cultivars. A reliable method for the detection and quantification of F. oxysporum f. sp. ciceris in soil and chickpea tissues would contribute much to implementation of those disease management strategies. In this study, we developed a real-time quantitative polymerase ch...

In this study, bacterial strains were isolated from soils from 30 locations of Samcheok, Gangwon province. Of the isolated strains, seven showed potential plant growth promoting and antagonistic activities. Based on cultural and morphological characterization, and 16S rRNA gene sequencing, these strains were identified as Paenibacillus species. All seven strains produced ammonia, cellulase, hyd...

Growth of alfalfa (Medicago sativa cv. Vernal) seedlings was compared after inoculation with combinations of either Pratylenchus penetrans and Fusarium soloni or P. penetrans and F. oxysporum f. sp. medicaginis. A synergistic disease interaction occurred in alfalfa when F. oxysporum and P. penetrans were added simultaneously to the soil. Alfalfa growth was suppressed at all inoculum levels of P...
