Available in PDF, EPUB and Kindle. Book excerpt: A greenhouse experiment was conducted in 1991 and in 1992 to determine the effect of soil water pressure on potato (cv Russet Burbank) plant growth and infection by Verticillium dahliae. Soil water pressures of -0.01, -0.03, -0.08, or -0.15 MPa were combined factorially with two inoculum concentrations, 0 or 10 and 0 or 25 colony forming units per gram of soil in 1991 and 1992, respectively. Plants were sampled destructively over a 4 wk period. Dry weight of foliage, fresh weight of below ground plant material, root length, and root and vascular colonization by V. dahliae were determined. In weeks 3 and 4, change in foliar dry weight in response to the level of one independent variable depended on the level of the other. This interaction between soil water pressure and inoculum density was such that foliar dry weight was reduced in infested compared to noninfested soil at -0.01 MPa but not at other soil water pressures. There were no significant main effect interactions on below ground fresh weight or on root length. There was, however, a main effect of soil water pressure on root length in which length decreased as soil water pressure increased. In both years, colony density in roots (cfu/cm or cfu/g) was reduced at -0.01 MPa compared to lower soil water pressures. Colonization of vascular tissue (cfu/ml stem sap) was significantly reduced at -0.01 MPa compared to lower soil water pressures. Although V. dahliae and soil water pressure at -0.01 MPa interactively reduced foliar growth of plants, there were no corresponding significant increases in population densities of the pathogen in roots or stems.

Book excerpt: In the potato (Solanum tuberosum L.) industry, the asexual soilborne fungal pathogen Verticillium dahliae Kleb. causes Verticillium wilt, resulting in up to 50% yield losses. Some prevalent clonal lineages of V. dahliae causing disease in potato are the highly host specific and aggressive lineage 4A and the less aggressive lineage 4B. Isolates in lineage 4B can endophytically colonize hosts other than potatoes, such as common weeds growing on field margins or between crops. The full host range of species that can asymptomatically harbor V. dahliae and the frequency of this colonization on weeds is unknown. Asymptomatic hosts may also be sources of microsclerotia, the primary inoculum. To further characterize these asymptomatic endophytic interactions, I examined V. dahliae lineage 4A and 4B colonization of eight weed species in a controlled greenhouse experiment to assess the frequency of endophytic colonization. I found that plant family and plant species influenced the amount of V. dahliae infection in plants. However, there were some unexpected aspects of the experiment, including a lack of expected Verticillium wilt symptoms on potatoes and amplification of V. dahliae in the un-inoculated treatment. In addition to my greenhouse experiment, another goal was to develop specific detection methods for V. dahliae clonal lineages 4A and 4B. One primer set designed to detect 4A specifically had promising results and was able to amplify the full diversity of 4A isolates without off-target amplification of other lineages. Currently, diagnostic markers that differentiate clonal lineages of 4A and 4B of V. dahliae are not available, and assigning an isolate to a clonal lineage still involves the long and culture-dependent process of testing VCGs via nit mutants or sequencing. Designing a conventional multiplex PCR assay would allow for quicker detection and identification of 4A and 4B from plants, soil, or cultures. Providing researchers tools to identify and differentiate lineages in potato fields rapidly will allow further understanding of the nature of these clonal lineages and how their dynamics may impact disease. This will ultimately enable growers to make more informed decisions in managing the pathogen.
