“…In Manitoba, durum production averaged 67 834 ha or 5.4% of total wheat production in Manitoba from 1941 to 1990. While there was a growth in the CWRS seeded area from 1980 to 2000, the area seeded to durum further declined in the early 1990s, primarily due to the susceptibility of durum cultivars to the FHB epidemics that occurred in Manitoba during the 1990s (Gilbert and Tekauz 2000) and 2000s.…”

“…Incorporating resistance to FHB has been a high priority since severe epidemics started occurring in southern Manitoba in the early 1990s (Gilbert and Tekauz 2000). FHB caused yield reductions and mycotoxin accumulation caused by the pathogen (Gilbert and Tekauz 2000).…”

Wheat is Canada's largest crop with most of the production in the western Canadian prairie provinces of Manitoba, Saskatchewan and Alberta. Since wheat production started in western Canada, over 100 yr ago, market classes of hexaploid spring bread wheat (Triticum aestivum L.) were the dominant type of wheat, although production of durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn.)] has grown significantly over this period, and hexaploid winter wheat was grown on a relatively small portion of the wheat area. Within hexaploid wheat there has been diversification into a number of market classes based on different end-use quality criteria. The predominant spring bread wheat class has been the Canada Western Red Spring (CWRS) class. A few cultivars were grown extensively over a long period of time, such as the CWRS wheat Thatcher, which was the dominant cultivar from 1939 to 1968, and Kyle, which was the leading Canada Western Amber Durum (CWAD) cultivar from 1988 to 2004. Other cultivars dominated particular wheat classes for many years such as Glenlea, Canada Western Extra Strong (CWES) spring wheat and Norstar, Canada Western Red Winter (CWRW) wheat. The reasons for newer cultivars replacing older cultivars include improvements in grain yield, resistance to stem rust (Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. & E. Henn.), leaf rust (Puccinia triticina Eriks.), and other diseases, resistance to wheat stem sawfly (Cephus cinctus Nort.), enhanced end-use quality, and other agronomic characteristics such as lodging resistance. Cultivars with improved pest resistance were often rapidly adopted, such as Thatcher and Selkirk, in response to the stem rust epidemics in the 1930s and 1950s, and Rescue and Lillian in response to wheat stem sawfly epidemics in the 1940s and 2000s. Improved grain yield led to the rapid increase of many cultivars including Marquis in the 1910s and 1920s, Neepawa, Wascana and Wakooma in the 1970s, AC Barrie in the 1990s, and Superb in the 2000s. Increased breeding efforts recently have led to many more highly adapted cultivars and subsequently more diverse wheat production. Wheat classes and cultivars in the prairies continue to improve and diversify to meet the challenges of the marketplace and the production concerns of wheat growers.

“…Fusarium graminearum Schwabe [teleomorph Gibberella zeae (Schw.) Petch] is the major pathogen responsible for this disease, but other Fusarium species, especially Fusarium culmorum, also play a role (Gilbert & Tekauz, 2000). Pathogens of the genus Fusarium can also cause head blight and root rot on many other plant species.…”

A secreted lipase encoded by LIP1 is necessary for efficient use of saturated triglyceride lipids in Fusarium graminearum

et al. 2005

A triglyceride lipase gene LIP1 was identified in the genome of Fusarium graminearum strain PH-1. The predicted protein encoded by LIP1 contains 591 amino acid residues with a putative N-terminal signal peptide and shows 57 and 40-44 % identity to a Botrytis cinerea lipase and five Candida rugosa lipases, respectively. Yeast cells overexpressing LIP1 showed lipolytic activity against a broad range of triglyceride substrates. Northern blot analyses revealed that expression of LIP1 was activated in planta during the fungal infection process. LIP1 expression was strongly induced in minimal medium supplemented with wheatgerm oil, but only weakly induced by olive oil and triolein. In contrast, supplementation with other carbon sources, including glucose, sucrose, apple pectin and wheat cell-wall material, did not induce LIP1 expression. Saturated fatty acids were the strongest inducers for LIP1 expression and this induction was suppressed proportionally by the presence of the unsaturated fatty acid. To determine the potential function of LIP1, gene replacement was conducted on strain PH-1. When compared with wild-type PH-1, DLIP1 mutants showed greatly reduced lipolytic activities at the early stage of incubation on minimal medium supplemented with either saturated or unsaturated lipid as the substrate, indicating that LIP1 encodes a secreted lipase for exogenous lipid hydrolysis. Moreover, the DLIP1 mutants exhibited growth deficiency on both liquid and solid minimal media supplemented with the saturated triglyceride tristearin as the sole carbon source, suggesting that LIP1 is required for utilization of this substance. Despite these differences, no variation in disease symptoms between the DLIP1 mutants and the wild-type strain was observed on susceptible cereal hosts.

Tamburic-Ilincic, L. 2010. Fusarium species and mycotoxins associated with oat in southwestern Ontario, Canada. Can. J. Plant Sci. 90: 211Á216. Fusarium graminearum Schwabe [teleomorph: Gibberella zeae Schwein. Petch] is the predominant Fusarium species pathogenic to wheat, barley and corn in Ontario and produces the mycotoxin deoxynivalenol (DON) in grain. The first objective of this study was to determine the Fusarium spp. and mycotoxin concentrations (DON, HT-2, and T-2) from commercial oat (Avena sativa L.) fields grown in the same area as wheat, corn and barley in Ontario. The second objective was to measure DON level across cultivars grown in the Ontario Performance Trial (OPT) after sprayinoculation with F. graminearum. Fusarium sporotrichioides, F. graminearum and F. poae were the predominant species identified in oat.
