Fusarium oxysporum is an anamorphic species that includes both pathogenic and nonpathogenic strains. Plant pathogenic forms cause a wilt disease and are grouped into formae speciales based on their host range; some are further subdivided into pathogenic races. Many formae speciales are comprised of multiple clonal lineages and, in some cases, a pathogenic race is associated with more than one clonal lineage, suggesting independent origins. Although some evidence suggests one pathogenic race may…

The Fusarium oxysporum species complex (FOSC) comprises a multitude of strains that cause vascular wilt diseases of economically important crops throughout the world. Although sexual reproduction is

Current Status of Fusarium oxysporum Formae Speciales and Races.

This review raises issues regarding the nomenclature and the description of F. oxysporum formae speciales and races, together with 37 insufficiently documented ones, and updated knowledge on races and host ranges.

Non-pathogenic Fusarium oxysporum as a biocontrol agent

This review paper attempts to describe various aspects of non-pathogenic F. oxysporum isolates and the possible threats in their usage as biocontrol agents.

Epitypification of Fusarium oxysporum – clearing the taxonomic chaos

Using multi-locus phylogenetic inference and subtle morphological differences with the newly established epitype of F. oxysporum as reference point, 15 cryptic taxa are resolved in this study and described as species.

The Fusarium oxysporum f. sp. ciceris/Cicer arietinum pathosystem: a case study of the evolution of plant-pathogenic fungi into races and pathotypes.

The use of resistant cultivars is one of the most practical and cost-efficient strategies for managing plant diseases. However, the efficiency of resistant cultivars in disease management is limited

Recent developments in the molecular discrimination of formae speciales of Fusarium oxysporum.

An increasing number of studies have reported the successful development of molecular markers to discriminate F. oxysporum strains below the species level, which is highly desirable for effective disease management.

Comparative analysis of pathogenic and nonpathogenic Fusarium oxysporum populations associated with banana on a farm in Minas Gerais, Brazil

To explore if the ‘local’ Foc isolates had acquired pathogenicity either independently through co-evolution with the host, or through horizontal gene transfer (HGT) of pathogenic genes from other, probably introduced, Foc isolate, the presence and sequence of putative SIX effector genes were analyzed and this observation supports the HGT hypothesis.

The presence of a virulence locus discriminates Fusarium oxysporum isolates causing tomato wilt from other isolates.

It is shown that, despite their polyphyletic origin, isolates belonging to f.sp.

Fusarium oxysporum: Genomics, Diversity and Plant–Host Interaction

Comparative genomics of four Fusarium species have led to identification of basic and specialized/dynamic pathogenicity genes that confer host specialization, and regulation of host and tissue specificity is still not known.

Genetic Diversity of Fusarium Wilt Disease of Banana

The population of this fungus inoutheast Asia shows a high degree of variation, suggesting that Foc lineages evolved together with their hosts in Southeast Asia, and it has been suggested that FOC has multiple independent evolutionary origins, both within and outside of the Musaceae origin center.



Population structure and the relationship between pathogenic and nonpathogenic strains of Fusarium oxysporum

Twenty-nine strains from this collection, each representing a different vegetative compatibility group, were found to be nonpathogenic to muskmelon in greenhouse seedling tests.

Genetic variation in Fusarium oxysporum from cyclamen

Fusarium isolates were recovered from cyclamen plant material and from public culture collections, and the majority (79/90) were F. oxysporum, although isolates of F. moniliforme, F. equiseti, and F. graminearum also were recovered.

Vegetative compatibility groupings in a local population of Fusarium oxysporum

One hundred isolates of Fusarium oxysporum collected from soil in the San Joaquin Valley in 1988 were tested for their ability to form intra- and inter-isolate heterokaryons, and the result suggests that anastomosis occurs infrequently among isolates in this population.

Vegetative compatibility groups in Fusarium oxysporum f. sp. lycopersici

A worldwide collection of 115 isolates of Fusarium oxysporum f. sp. lycopersici from tomato was examined for pathogenicity, colony morphology, and vegetative compatibility. No correlations were found

Classification of strains of Fusarium oxysporum on the basis of vegetative compatibility.

Twenty-one strains of Fusarium oxysporum were classified on the basis of vegetative compatibility or the ability to form hetcrokaryons, and there was some evidence for a correlation between VCG and forma specialis.

Fusarium oxysporum f. sp. cubense Consists of a Small Number of Divergent and Globally Distributed Clonal Lineages.

Several lines of evidence indicated that this pathogen has a clonal population structure, and individuals with identical haplotypes were geographically dispersed and clone-corrected tests of gametic disequilibrium indicated significant nonrandom association among pairs of alleles for 34 of 36 loci tested.

Further investigations of vegetative compatibility within Fusarium oxysporum f.sp. melonis

One hundred and nineteen strains of Fusarium oxysporum f.sp. melonis were characterized by virulence and vegetative compatibility. One hundred and seven strains were placed in four previously

Physiologic races and vegetative compatibility groups of Fusarium oxysporum f. sp. melonis in Israel

Two vegetative compatibility groups (VCGs) and four physiologic races (0, 1, 2, and 1-2) were identified among 122 isolates of Fusarium oxysporum f. sp. melonis in Israel. One VCG corresponded to the

Local and regional variation in populations of Fusarium oxysporum from agricultural field soils

This is the first report from North America of race 1,2, for which there is presently no resistance in muskmelon, and the two VCGs associated with virulent isolates also included four nonpathogenic isolates.

Characterization of a single clonal lineage of Fusarium oxysporum f.sp. albedinis causing Bayoud disease of date palm in Morocco.

Close genetic relationships between the isolates provides evidence that Moroccan F. albedinis populations may belong to a single clonal lineage that originated in Moroccan palm groves and eventually reached the Algerian oases.
