Multilocus Analysis

Sugar beet (Beta vulgaris) Fusarium yellows is caused by Fusarium oxysporum f. sp. betae and can lead to significant reductions in root yield, sucrose percentage, juice purity, and storability. F. oxysporum f. sp. betae can be highly variable and many F. oxysporum strains isolated from symptomatic sugar beet are nonpathogenic. Identifying pathogenicity factors and their diversity in the F. oxysporum f. sp. betae population could further understanding of how this pathogen causes disease and potentially provide molecular markers to rapidly identify pathogenic isolates. This study used several previously described fungal effector genes (Fmk1, Fow1, Pda1, PelA, PelD, Pep1, Prt1, Rho1, Sge1, Six1, Six6, Snf1, and Ste12) as genetic markers, in a population of 26 pathogenic and nonpathogenic isolates of F. oxysporum originally isolated from symptomatic sugar beet. Of the genes investigated, six were present in all F. oxysporum isolates from sugar beet (Fmk1, Fow1, PelA, Rho1, Snf1, and Ste12), and seven were found to be dispersed within the population (Pda1, PelD, Pep1, Prt1, Sge1, Six1, and Six6). Of these, Fmk1, Fow1, PelA, Rho1, Sge1, Snf1, and Ste12 were significant in relating clade designations and PelD, and Prt1 were significant for correlating with pathogenicity in F. oxysporum f. sp. betae.

Cysts of Heterodera schachtii from sugar-beet (Beta vulgaris) fields and cysts of Globodera rostochiensis and G. pallida from potato (Solanum tuberosum) fields in northern Belgium, as well as egg masses and females of Meloidogyne hapla from a tomato (Lycopersicon esculentum) field in the Flemish-Brabant province, Belgium, were collected and examined for the presence of fungi. Of the total of 374 cysts of H. schachtii, 57.7% were colonized by one or more of 18 different species of fungi, all of which were from the genra Acremonium, Chaetomium, Cylindrocarpon, Fusarium, Gliocladium, Humicola, Mariannaea, Nematophthora, Periconia, Phoma, and Verticillium, and 45.3% of the 726 cysts of Globodera spp. were colonized by one or more of 18 different species, from the same gene. Of the 160 egg masses of M. hapla, 32% were colonized by one or more of 18 species of the genra Arthrobotrys, Cylindrocarpon, Fusarium, Monacrosporium, Paecilomyces, Phoma, Plectosphaerella, and Verticillium, while 31% of the 160 females were colonized by 12 species, from the same gene except Paecilomyces and Plectosphaerella. Fusarium oxysporum was by far the predominant species in both the cyst and root-knot nematodes. A black yeast-like fungus was found in cysts.

Five fungicides were each applied on sugar beet (Beta vulgaris) three times at about 14-day intervals beginning in July in 2005 through 2008. No foliar disease occurred in the nontreated control or any fungicide treatment. There were no significant differences in root yield, recoverable sucrose, or sucrose concentration among treatments. In 2007 and 2008, postharvest storage respiration rates were determined after 30 and 90 days in storage. There was no significant difference in respiration rates among treatments. There was no apparent benefit in applying these fungicides in seasons when no foliar disease developed. Accepted for publication 7 September 2009. Published 19 October 2009.
