“…Isolates of F. oxysporum in the same VCG typically possess similar or identical multilocus haplotypes (Kistler 1997;Kistler et al 1998). Therefore, VCGs can be good predictors of genetic similarity, clonal lineage, or both (Kistler 1997;Kistler et al 1998).…”

Physiological races and vegetative compatibility groups of butterhead lettuce isolates of Fusarium oxysporum f. sp. lactucae in Japan

et al. 2004

Races were identified among butterhead lettuce isolates of Fusarium oxysporum f. sp. lactucae collected from three geographical areas of Hokkaido, Shizuoka, and Fukuoka in Japan by inoculation tests using Fujinaga's race differential cultivars of lettuce (i.e., Patriot, Costa Rica No. 4, and Banchu Red Fire). Eighteen isolates from Shizuoka and Fukuoka were designated race 3, with two unknown vegetative compatibility groups (VCGs) that differed from Ogiso's VCG 1 and 2. These two new VCGs were obtained from both Shizuoka and Fukuoka. On the other hand, three isolates from Hokkaido were classified as race 1 and identified as VCG 1, which represents a VCG of crisphead isolates from Nagano.

“…Detailed studies have shown that strains belonging to the same VCG typically have very similar or identical multi-locus haplotypes and belong to the same clonal lineage. Consequently, VCGs can be good predictors of genetic similarity, clonal lineage, or both (Kistler et al, 1998).…”

SUMMARYVisual assessment of phenotypes, performed when two strains of one fungal species are cultivated in a mixed culture on specific media, is known as vegetative or heterokaryotic compatibility or incompatibility test, which enables identification of fungal clones and their classification based on phylogenetic groups. Hyphae of strains that have identical alleles at all vic loci can anastomose into a form of a visible heterokaryon. Strains that divide compatible loci and can anastomose each other belong to a subpopulation termed the vegetative compatibility group (VCG), which is genetically distinguishable from other VCGs. Each VCG is specific regarding its host plant or related host groups and can, but does not have to be virulent on other hosts.Vegetative compatibility can be established in different ways, but complementary auxotrophic strains or strains formed by spontaneous mutation during nutrition, capable of forming a prototrophic heterokaryon are predominantly used. The nit mutants are considered excellent genetic markers for determination of vegetative compatibility and grouping of strains or clones of one fungus into the same or different VCGs. The ability only to determine whether strains are the same or not, but not the degree of their relatedness using VCG, is a limiting factor in analyses that could be performed. VCGs are the most efficient when they are employed to detect the presence of a specific strain in a population.This paper provides an overview of the importance of the phenomenon of vegetative compatibility. Vegetative compatibility is one of the most important genetic traits in ascomycetes by which one subpopulation can be identified as a distinct genetic group. Furthermore, the procedures for isolation, identification and determination of nit mutant phenotypes, and for identification of complementary strains and VCGs are described in detail.

“…The absence of wild-type growth between complementary nit mutants derived from the same parent isolate indicated alletic or vegetative self-incompatibility, whereas the absence of wild-type growth between nit mutants from different parent isolates indicated either noncomplementarity or inability to form a heterokaryon because of lack of vegetative compatibility (Katan et al 1991). VCGs were numbered according to Kistler et al (1988) and Katan (1999). The complementation pairings were carried out at least twice for each isolates with different nit mutants.…”
