The pathogenicity of Verticillium albo-atrum as affected by muck soil antagonists.
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...
متن کاملInvestigating Agrobacterium-Mediated Transformation of Verticillium albo-atrum on Plant Surfaces
BACKGROUND Agrobacterium tumefaciens has long been known to transform plant tissue in nature as part of its infection process. This natural mechanism has been utilised over the last few decades in laboratories world wide to genetically manipulate many species of plants. More recently this technology has been successfully applied to non-plant organisms in the laboratory, including fungi, where t...
متن کاملRelative Activities and Characteristics of Some Oxidative Respiratory Enzymes from Conidia of Verticillium albo-atrum.
Conidia of Verticillium albo-atrum Reinke and Berthold, collected from shake cultures grown in Czapek broth, were sonified for 4 or 8 minutes or ground frozen in a mortar to obtain cell-free homogenates. These were assayed for certain enzymes associated with respiratory pathways. Malic dehydrogenase was the most active, glucose-6-P and NADH dehydrogenase were less active, NADH-cytochrome c redu...
متن کاملInfluence of Water Activity, Temperature, and Their Interaction on Germination of Verticillium albo-atrum Conidia.
Conidia were germinated at three temperatures in media in which available water, expressed as water activity, was controlled at three levels. Rate of germination in the basal medium (0.9964 water activity) was most rapid at 25 C and was inhibited at 15 and 30 C. Lowering the water activity at a particular temperature decreased rates of germination. However, at a low water activity (0.9778) germ...
متن کاملDevelopment of a Real-Time Polymerase Chain Reaction Assay for Quantifying Verticillium albo-atrum DNA in Resistant and Susceptible Alfalfa.
ABSTRACT A precise real-time polymerase chain reaction (PCR) assay was developed for quantifying Verticillium albo-atrum DNA. The assay was used in a repeated experiment to examine the relationship between the quantity of pathogen DNA detected in infected leaves and shoots and the severity of Verticillium wilt symptoms in several alfalfa cultivars expressing a range of disease symptoms. Plants ...
