Genomic Regions Associated with Tolerance to Freezing Stress and Snow Mold in Winter Wheat
Plants grown through the winter are subject to selective pressures that vary with each year's unique conditions, necessitating tolerance of numerous abiotic and biotic stress factors. The objective of this study was to identify molecular markers in winter wheat (Triticum aestivum L.) associated with tolerance of two of these stresses, freezing temperatures and snow mold-a fungal disease complex...
متن کاملMycelial growth, sclerotial production and carbon utilization of three Typhula species
The mycelial growth, sclerotial production, and carbon utilization of the snow mould biocontrol agent Typhula phacorrhiza Fries were compared with the two grey snow mould fungi, Typhula ishikariensis Imai and Typhula incarnata Lasch ex Fries. Variation was observed among the four isolates for each species, but there was greater variation among species. All three species were able to grow at the...
متن کاملEfficacy of Typhula phacorrhiza as a biocontrol agent of grey snow mould of creeping bentgrass
Isolates of the fungus Typhula phacorrhiza Fries (TP) were evaluated in field tests over a 3-year period for suppression of grey snow mould caused by Typhula ishikariensis Imai (Tish) and Typhula incarnata Lasch ex Fr. (Tinc). Isolates of TP were collected across southern Ontario in the spring of 1994. In December 1994, 46 of these isolates, which had been cultured on mixed grains, were applied...
متن کاملIce-binding site of snow mold fungus antifreeze protein deviates from structural regularity and high conservation.
Antifreeze proteins (AFPs) are found in organisms ranging from fish to bacteria, where they serve different functions to facilitate survival of their host. AFPs that protect freeze-intolerant fish and insects from internal ice growth bind to ice using a regular array of well-conserved residues/motifs. Less is known about the role of AFPs in freeze-tolerant species, which might be to beneficiall...
متن کاملRole of ice nucleation and antifreeze activities in pathogenesis and growth of snow molds.
ABSTRACT We examined the ability of snow molds to grow at temperatures from -5 to 30 degrees C and to influence the growth of ice through assays for ice nucleation and antifreeze activities. Isolates of Coprinus psychromorbidus (low temperature basidiomycete variant), Microdochium nivale, Typhula phacorrhiza, T. ishikariensis, T. incarnata, and T. canadensis all grew at -5 degrees C, whereas Sc...
