Dahlia is a popular tuberous rooted perennial herbaceous flowering plant that prized for its privileged and spectacularly stunning flowers extremely desirable in the landscape. It has no equal as bed flower terms of versatility, attractiveness, even cost, cultivars can keep them looking beautiful more than month. Growing medium essential growth because it provides nutrients, anchors plant, mine...

The soilborne fungus Verticillium dahliae is the major pathogen that causes the verticillium wilt disease of plants, which leads to huge economic loss worldwide. At the early stage of infection, growth of the pathogen is subject to the nutrition stress of limited nitrogen. To investigate the secreted pathogenic proteins that play indispensable roles during invasion at this stage, we compared th...

A new strain of Verticillium dahliae, the fungus causing Verticillium leaf mottle and wilt, was identified from northwestern Minnesota in 2002. The new strain or biotype is characterized by its ability to overcome the single, dominant V-1 resistance gene employed in oilseed and confection hybrids. Samples collected in 2003 from diseased plants confirmed the new biotype also exists in Manitoba, ...

Resistance in tomato against race 1 strains of the fungal vascular wilt pathogens Verticillium dahliae and V. albo-atrum is mediated by the Ve locus. This locus comprises two closely linked inversely oriented genes, Ve1 and Ve2, which encode cell surface receptors of the extracellular leucine-rich repeat receptor-like protein (eLRR-RLP) type. While Ve1 mediates Verticillium resistance through m...

There are few reports of the application of antibiosis as a possible means of controlling Verticillium alboatrum Reinke and Berthold. Most of these publications are concerned with in vitro studies which report the effects of various organisms or their products on V. albo-atrum (Ark and Hunt, 1941; Arnstein et al., 1948; Smith, 1947). Wilhelm (1951a) effected a reduction in the inoculum potentia...

Knowledge of pathogen biology and genetic diversity is a cornerstone of effective disease management, and accurate identification of the pathogen is a foundation of pathogen biology. Species names provide an ideal framework for storage and retrieval of relevant information, a system that is contingent on a clear understanding of species boundaries and consistent species identification. Verticil...
