“…However, in the current research, varieties Kraljica and Galloper exhibited an increase in sarcosine levels following Fusarium treatment, compared to control plants. Nevertheless, amino acids represent building blocks for several other biosynthetic pathways and play pivotal roles during signaling processes as well as in plant stress response [ 55 ], besides their fundamental role in synthesis of peptides and proteins [ 12 ]. Sarcosine has a role as methyl donor for antioxidative metabolites in plant stress metabolism [ 56 ].…”

“…Although the majority of the Fusarium species can be found in nearly all FHB-affected areas, F. graminearum appears in a wide range of environmental conditions, making it greatly adapted compared to other species [ 9 ]. Since F. graminearum is one of the most important Fusarium species in Croatia [ 5 , 11 ], during anthesis, when the temperature and humidity are high enough to promote fungal development, it infects the open flowers of host plants [ 12 ]. Besides grain yield and quality losses, of particular concern during the Fusarium infestation is the accumulation of mycotoxins, which affect all organisms, including humans [ 13 ].…”

“…Besides grain yield and quality losses, of particular concern during the Fusarium infestation is the accumulation of mycotoxins, which affect all organisms, including humans [ 13 ]. However, mycotoxins as secondary metabolites produced by toxigenic fungi of the genus Fusarium [ 4 , 12 ] are not the same as the metabolites produced by wheat plants that have a role in FHB defense [ 14 ]. Although many sources of moderate FHB resistance have been identified [ 15 ], significant progress has been recently made in mapping quantitative trait loci (QTL) for FHB resistance [ 16 ] and developing FHB-resistant varieties [ 17 ].…”

Fusarium head blight (FHB) is one of the most dangerous diseases of winter wheat, resulting in reduced grain yield and quality, and production of mycotoxins by the Fusarium fungi. In the present study, changes in the grain metabolomics of winter wheat samples infected with Fusarium spp. and corresponding non-infected samples from two locations in Croatia were investigated by GC-MS. A Mann–Whitney test revealed that 24 metabolites detected were significantly separated between Fusarium-inoculated and non-infected samples during the variety by treatment interactions. The results confirmed that in grains of six FHB-resistant varieties, ten metabolites were identified as possible resistance-related metabolites. These metabolites included heptadecanoic acid, 9-(Z)-hexadecenoic acid, sophorose, and secolaganin in grains of FHB-resistant varieties at the Osijek location, as well as 2-methylaminomethyltartronic acid, maleamic acid, 4-hydroxyphenylacetonitrile, 1,4-lactonearabinonic acid, secolaganin, and alanine in grains of FHB-resistant varieties at the Tovarnik location. Moreover, on the PCA bi-plot, FHB-susceptible wheat varieties were closer to glycyl proline, decanoic acid, and lactic acid dimer that could have affected other metabolites, and thus, suppressed resistance to FHB. Although defense reactions were genetically conditioned and variety specific, resulting metabolomics changes may give insight into defense-related pathways that could be manipulated to engineer plants with improved resistance to the pathogen.

“…The pathogen alters the amino acid composition of the kernel (Beyer and Aumann 2008) while causing reduction in yield and grain quality. The total estimated economic loss was $7.67 billion from FHB in hard red spring, soft red winter, durum wheat and barley from 1993 to 2001 (Nganje et al 2004).…”

Genotyping-by-sequencing to remap QTL for type II Fusarium head blight and leaf rust resistance in a wheat–tall wheatgrass introgression recombinant inbred population

Fusarium graminearum Schwabe (Fusarium head blight, FHB) and Puccinia triticina Eriks (leaf rust) are two major fungal pathogens posing a continuous threat to the wheat crop; consequently, identifying resistance genes from various sources is always of importance to wheat breeders. We identified tightly linked single nucleotide polymorphism (SNP) markers for the FHB resistance quantitative trait locus (QTL) Qfhs.pur-7EL and the leaf rust resistance locus Lr19 using genotyping-by-sequencing (GBS) in a wheat-tall wheatgrass introgression-derived recombinant inbred line (RIL) population. One thousand and seven hundred high-confidence SNPs were used to conduct the linkage and QTL analysis. Qfhs.pur-7EL was mapped to a 2.9 cM region containing four markers within a 43.6 cM segment of wheatgrass chromosome 7el 2 that was translocated onto wheat chromosome 7DL. Lr19 from 7el 1 was mapped to a 1.21 cM region containing two markers in the same area, in repulsion. Five lines were identified with the resistance-associated SNP alleles for Qfhs.pur-7EL and Lr19 in coupling. Two SNP markers in the Qfhs.pur-7EL region were converted into PCR-based KASP markers. Investigation of the genetic characteristics of the parental lines of this RIL population indicated that they are translocation lines in two different wheat cultivar genetic backgrounds instead of 7E-7D substitution lines in Thatcher wheat background, as previously reported in the literature.

“…Wheat is typically milled into flour which is used to make a wide range (El Jarroudi et al, 2012b). Beyond reducing yield, Fusarium species reduce the quality by release of toxic secondary metabolites in the grain and by modifying the amino acid profile of winter wheat (Beyer and Aumann, 2008). To ensure beneficial outcomes in their farming practice, Luxemburgish famers typically use stress and disease resistant cultivars, in conjunction with suitable management practices (for example, crop rotation).…”

a b s t r a c tFoliar fungicides in wheat are typically used to safeguard against economic losses from diseases. In this study, we assessed the effects of three fungicide spray regimes [single, double, and triple treatments] on four different grain quality parameters [thousand grain weight (TGW), test weight (TW), grain protein content (GPC), and Zeleny sedimentation volume (ZSV)] during the 2006-2009 period at two sites in Luxembourg. The fungicides used were generally a mix of chlorothalonil and triazoles. At Burmerange, (cultivar Cubus), the values of TGW, TW, GPC and ZSV ranged from 38 to 62 g, 67 to 83 kg hl −1 , 12.0% to 14.7% dry matter (DM), and 27 to 54 ml, respectively. Whereas, at Everlange (cultivar Achat), the ranges of TGW, TW, GPC and ZSV were 42 to 65 g, 65 to 81 kg hl −1 , 11.0% to 15.0% DM, and 21 to 66 ml, respectively. In more than 75% cases, the results indicate that fungicides did not significantly affect TW or ZSV at either sites (P > 0.05). However, there was a significant and positive fungicide effect on GPC in 2006 and 2009 at Burmerange, and only in 2006 at Everlange (P < 0.05). On the contrary, TGW was significantly affected at Burmerange in all years, except 2008 when a positive increase was observed compared to control plots; and in 2006 and 2007 at Everlange. Interestingly, when there was an effect of fungicides on a quality parameter, there was no difference among different fungicide treatments. Thus under conditions prevailing in Luxembourg, a single fungicide treatment applied with judicious timing generally resulted in statistically similar grain quality parameters when compared with a double or triple fungicide treatment.
