Abstract

The development of wheat (Triticum aestivum L.) cultivars resistant to Fusarium head blight (FHB) (caused by Fusarium graminearum Schwabe) requires screening methodologies that accurately characterize reaction to this disease. The objectives of this study were (i) to characterize the stability of cultivars for their FHB reaction and (ii) to define an optimum resource allocation for FHB evaluation. Fourteen cultivars were evaluated in FHB-screening nurseries at two locations across a 4-yr period. Field data were used to calculate disease incidence (INC) as the frequency of symptomatic spikes and disease index (DIS) as the mean disease score of all spikes. FHB reaction also was evaluated on harvested grain as percent visually scabby kernels (VSK) and deoxynivalenol (DON) concentration. Significant differences among cultivars for all FHB parameters were found in each environment. Pearson correlation coefficients among FHB parameters were positive and highly significant, ranging from 0.32 between INC and DON to 0.72 between INC and DIS. Spearman rank correlation coefficients for yearly cultivar rankings and Kendall's coefficient of concordance were high, indicating similarity of the rankings of the tested cultivars in different environments. Visually scabby kernels was the FHB parameter with highest similarity for cultivar ranking across environments. Most of the cultivars, including susceptible ones, expressed stability for FHB reaction. Optimum resource allocation for DIS was most affected by the number of environments with three being the minimum to accurately characterize a genotype's resistance level. Using more than three replications or scoring more than 10 spikes per plot had little practical value in characterizing FHB reaction., FUSARIUM HEAD BLIGHT, caused primarily by Fusarium graminearum, is an important disease throughout major spring wheat-production regions of the USA, Canada, and other parts of the world.

Abstract

Fusarium head blight (FHB) is a disease problem (primarily caused by Fusarium graminearum Schwabe) that affects the quality and yield of barley (Hordeum vulgare L.) grain. The objectives of this study were to identify the location of quantitative trait loci (QTL) for resistance to FHB in a two-rowed by six-rowed population, to examine the association of FHB resistance with heading date and the Vrs1 (two-rowed spike morphology) locus, to validate the location of the major FHB resistance QTL primarily detected in the field, and to identify simple sequence repeat (SSR) markers linked to the QTL for FHB resistance. We created a genetic map of 143 molcular markers from a population derived from the parents Fredrickson (two-rowed, moderately resistant) and Stander (six-rowed, susceptible). The Fredrickson/Stander population was evaluated in two field environments by a grain spawn inoculation method, two field environments by a spray inoculation, and two greenhouse environments. QTL analysis detected three distinct regions on chromosome 2(2H) associated with FHB resistance; two of these regions were also associated with resistance to deoxynivalenol (DON) accumulation. One FHB resistance QTL was also associated with heading date, while another FHB resistance QTL was found associated with the Vrs1 locus. The third FHB resistance QTL was detected only in the greenhouse, but was coincident with a QTL for resistance to DON accumulation in the field. All three QTL were detected in the greenhouse, indicating that this environment may be useful for selecting FHB resistant barley genotypes. SSR markers were identified that are linked with each QTL and could prove useful for marker-assisted trait manipulation. Finally, the two major QTL detected in the field were validated using an independent population with Fredrickson and Stander parents., FUSARIUM HEAD BLIGHT has become a significant disease problem in barley in several regions around the world. In 1993, FHB reemerged in the northern Great Plains causing about $406 million [...]

Abstract

[Synopsis] The correlation of deoxynivalenol (DON) and its incidence with Fusarium headblight of wheat and barley is very strong. However, the correlation with disease severity is weak. The focus of this presentation is on the role of DON in pathogenesis. Single-kernel analysis is the model system developed for the study of this disease. In natural infection, DON is found in spikelets other than those showing symptoms and is most likely due to spread of the fungus. In wheat and barley heads inoculated with DON, no translocation of DON out of the treated spikelets was noted after 12, 24 and 48 hrs. Macroconidia of F. graminearum isolates do not contain DON although these same isolates when grown on rice or wheat produce the toxin. In inoculated wheat and barley heads, DON as well as 15-ADON are produced 48 hrs after inoculation. Trichodiene mutants that do not produce DON did not do so when inoculated into single spikelets on wheat heads although they did show mild symptoms of infection. The wild type (DON producer) caused more severe symptoms of infection than the mutant. This manuscript attempts to review some of the pertinent literature relative to pathogenesis of Fusarium species on cereal grains as well as include some original experiments designed to address the role of deoxynivalenol in pathogenesis.

25. Trichothecene production is detrimental to early root colonization by Fusarium culmorum and F. graminearum in fusarium crown and root rot of wheat.

Abstract

Fusarium culmorum (Fc) and F. graminearum (Fg) belong to the predominant causal agents of fusarium crown and root rot (FCR) in wheat. While many studies have been done to investigate crown rot, including stem base infection, root colonization and mycotoxin production associated with root rot is not well understood. In this study the impact of mycotoxins on the colonization of wheat roots and stem bases was analysed by using Fc and Fg isolates that varied in both quantity and types of trichothecenes they produce. Seedling inoculations in growth chambers with a high deoxynivalenol (DON)‐ and 3‐acetyldeoxynivalenol (3ADON)‐producing isolate led to more severe symptoms and 20‐times greater colonization of the stem base, as measured by Fc DNA accumulation, than isolates that produced less DON/3ADON. In contrast to stem base colonization, in vitro inoculations of roots with a Tri5 deletion mutant deficient in Fg trichothecene production led to three‐times higher colonization than the wildtype. Furthermore, an Fc isolate that produced low levels of zearalenone resulted in twice the level of colonization of a high DON/3ADON‐producing isolate included in the study. When root inoculation with a low DON/3ADON‐producing Fc isolate was supplemented with exogenous DON, DON production decreased by more than half per unit weight of Fc DNA, and root colonization doubled compared to the untreated control. Therefore, in contrast to its potential role as an aggressiveness factor in stem base infection, trichothecene production by Fc and Fg is detrimental to the early stages of wheat root colonization in FCR.

Abstract

Grain yield, protein content, and straw strength are the three primary traits that growers consider when selecting wheat (Triticum aestivumL.) cultivars in the Red River Valley region of Minnesota and North Dakota. ‘Norden’ (Reg. No. CV‐1136, PI 667104) was released by the University of Minnesota Agricultural Experiment Station in 2012 because it represented a unique combination of these traits, in addition to good resistance to leaf rust (Puccinia triticinaEriks.) and Fusarium head blight (FHB, caused primarily by Fusarium graminearumSchwabe). Norden is a midmaturity, semidwarf cultivar that was selected in part because it contains the Lr34gene for adult plant leaf rust resistance and the Fhb1quantitative trait locus for FHB resistance.
