Abstract Rhg4 is a major genetic locus that contributes to soybean cyst nematode (SCN) resistance in the Peking-type of (Glycine max), which also requires rhg1 gene. By map-based cloning and functional genomic approaches, we previously showed gene encodes predicted cytosolic serine hydroxymethyltransferase (GmSHMT08); however, novel gain function GmSHMT08 SCN remains be characterized. Using forward screen, identified an allelic series mutants shed new light on mechanistic aspects...
The soybean cyst nematode (SCN), Heterodera glycines, is one of the most important pathogens soybean. Periodic monitoring SCN population densities and virulence phenotypes necessary for developing management strategies utilizing resistant cultivars, primary strategy used to combat this pest. Therefore, we conducted a statewide survey Missouri determine during 2015–2016 compared these results with similar in 2005. were determined 393 soil samples representing 74 soybean-producing counties...
Soybean cyst nematode (SCN) is an important pathogen of soybean causing >$1 billion in yield losses annually the United States. Planting SCN-resistant cultivars primary management strategy. Resistance genes derived from plant introduction (PI) 88788 (rhg1-b) and PI 548402 (Peking; rhg1-a Rhg4) are main types resistance available commercial cultivars. The rhg1-b allele found majority north central widespread use has led to limited options for farmers rotate sources manage SCN....
Abstract Southern root‐knot nematode (SRKN) is one of the most yield‐suppressing pathogens in soybean [( Glycine max (L.) Merr.] United States. With limited chemical and cultural management options, use genetic resistance efficient economical approach to control SRKN. A major quantitative trait locus (QTL) mapped chromosome 10 primary source cultivars; however, studies have been conducted evaluate its efficacy minimizing yield suppression under field conditions with SRKN pressure. This study...
The soybean cyst nematode Heterodera glycines is the most economically devastating pathogen of in United States and threatens to become even more damaging through selection virulent populations field that can overcome natural resistance mechanisms cultivars. This pathogen, therefore, demands intense transcriptomic/genomic research inquiries into biology its parasitic mechanisms. H. delivers effector proteins are produced specialized gland cells root enable infection. study proteins, thus,...
The majority of winegrape (<i>Vitis vinifera</i>) vineyards in Washington are planted with own-rooted grapevines, as opposed to grapevines grafted onto rootstock varieties. plant-parasitic nematode <i>Meloidogyne hapla</i> (common name: northern root-knot nematode) is commonly found vineyards, and susceptible this nematode. Before rootstocks used manage <i>M. or other horticultural characteristics Washington, their host status for should be defined. In greenhouse experiments, 10 commercially...
Southern root-knot nematode [SRKN, Meloidogyne incognita (Kofold & White) Chitwood] is a plant-parasitic challenging to control due its short life cycle, wide range of hosts, and limited management options, which genetic resistance the main option efficiently damage caused by SRKN. To date, major quantitative trait locus (QTL) mapped on chromosome (Chr.) 10 plays an essential role in SRKN soybean varieties. The confidence discovered trait-loci associations traditional methods often...
Bare-root production of Hemerocallis spp., daylily, is major economic importance to Michigan's ornamental industry, but clean nursery material challenging due plant-parasitic nematodes. The northern root-knot nematode, Meloidogyne hapla, the most important perennial pathogen in North America; it causes over 20% yield loss spp. and reduces marketability distribution. A field trial was established 2018 2020 at a Michigan commercial determine effective long-term management strategies reduce...
Michigan has the third largest floriculture industry in United States, with production of daylily (Hemerocallis spp.) a top commodity. Daylily is one most economically important ornamental plants, yet their plagued by plant-parasitic nematodes, especially northern root-knot nematode, Meloidogyne hapla. Based on previous field trials, seven treatments combination high-carbon, cow manure compost were selected for three-year trial at commercial nursery Zeeland, MI to discern best M. hapla...
Plants defend themselves chemically against herbivory through secondary metabolites and phytohormones. Few studies have investigated how constitutive variation in contributes to systemic response. We hypothesized that plants with lower defenses would induce a stronger phytohormone response spatially separated than high defense. used growth chamber bioassays investigate aboveground by Colorado potato beetle (Leptinotarsa decemlineata, CPB) belowground northern root-knot nematode (Meloidogyne...
