“…Damage caused by Fusarium fungus includes reduced grain yield and grain functional quality, and results in the presence of the mycotoxin deoxynivalenol in FDK (even in grains without any visible symptoms). The development of FHB resistant crop cultivars is an important component of integrated breeding management [58,59]. The objective of this investigation was to identify QTLs for traits linked to yield performance in a recombinant inbred line population grown under a disease-free environment and under conditions of Fusarium infection.…”

Fusarium head blight (FHB) is a devastating disease occurring in small grain cereals worldwide. The disease results in the reduction of grain yield, and mycotoxins accumulated in grain are also harmful to both humans and animals. It has been reported that response to pathogen infection may be associated with the morphological and developmental traits of the host plant, e.g. earliness and plant height. Despite many studies, effective markers for selection of barley genotypes with increased resistance to FHB have not been developed. In the present study, we investigated 100 recombinant inbred lines (RIL) of spring barley. Plants were examined in field conditions (three locations) in a completely randomized design with three replications. Barley genotypes were artificially infected with spores of Fusarium culmorum before heading. Apart from the main phenotypic traits (plant height, spike characteristic, grain yield), infected kernels were visually scored and the content of deoxynivalenol (DON) mycotoxin was investigated. A set of 70 Quantitative Trait Loci (QTLs) were detected through phenotyping of the mapping population in field conditions and genotyping using a barley Ilumina 9K iSelect platform. Six loci were detected for the FHB index on chromosomes 2H, 3H, 5H, and 7H. A region on the short arm of chromosome 2H was detected in which many QTLs associated with FHB-and yield-related traits were found. This study confirms that agromorphological traits are tightly related to FHB and should be taken into consideration when breeding barley plants for FHB resistance.

Fusarium head blight (FHB) is a devastating disease in small grain cereals worldwide. 14 The disease results in the reduction of grain yield and affects its quality. In addition, mycotoxins 15 accumulated in grain are harmful to both humans and animals. It has been reported that response 16 to pathogen infection may be associated with the morphological and developmental characteristics 17 of the host plant, e.g. the earliness and plant height. Despite the many studies the effective markers 18 for the selection of barley genotypes with increased resistance to FHB have not thus far been 19 developed. Therefore, exploring the genetic relationship between agronomic traits (e.g. heading 20 date or stem height) and disease resistance is of importance to the understanding of plant resistance 21 via "diesease escape" or dwarf stature. The studied plant material consisted of 100 recombinant 22 2 30 detected in the current study, in which many QTLs associated with FHB-and yield-related 31 characters were found. This study confirms that agromorphological traits are tightly related to the 32 FHB and should be taken into consideration when breeding barley plants for FHB resistance. 33 34 3 56 plants [9]. Although this method is widely used in the screening of resistant germplasms, the results 57 are subjective. Hence, different types of chromatography for identification and quantification of 58 mycotoxins in barley are commonly in use [10, 11]. However, due to the time-consuming and 59 costly nature of these methods, commercial immunometric assays, such as enzyme-linked 60 immunosorbent assay (ELISA), are frequently used for the monitoring of mycotoxin content [12, 61 13]. 62 Disease control is achieved by the deployment of resistant cultivars. However, breeding for 63 FHB resistance has proved difficult due to the complex inheritance of the resistance genes [14] 64 and the strong genotype-by-environment interaction [15]. 65 One of the several crop species most vulnerable to FHB infection is barley (Hordeum 66 vulgare L.). This species is a cereal crop of major importance, ranked the fourth grain crop in the 67 world in terms of production volume [16]. Its major uses are both as animal feed and as a 68 component of human nutrition [17, 18]. In addition, barley is perceived to be a model plant in 69 genetic study due to genome colinearity and synteny across rye, barley and wheat [19]. 70 Fusarium poses a real threat for barley plants especially in regions that are prone to have 71 long periods of wet weather during the flowering stage [4]. Host plants are most vulnerable to 72 infection during anthesis due to development of fungal spores on anthers and polen containg 73 nutrients [20]. Numerous morphological traits have been shown to be associated with FHB 74 resistance in barley [21]. Heading date, plant height, and spike characters (linked to spike 75 compactness) are mostly investigated [22, 23]. Days to heading is often negatively correlated with 76 FHB susceptibility and usually results in disease escape [24]. Hence...

Impact of Fusarium Head Blight on Wheat Flour Quality: Examination of Protease Activity, Technological Quality and Rheological Properties

et al. 2023

Wheat infections caused by Fusarium represent a global agricultural problem that reduces grain yield and negatively impacts wheat’s technological and rheological quality. Although fungal proteases or an increase in endogenous proteases due to Fusarium infection could negatively influence wheat storage proteins and dough performance, little research has been performed on either of these topics. The primary objective of this study was to identify the effect of Fusarium infection on protease activity in 25 wheat cultivars grown in two distinct locations in eastern Croatia. Apart from proteolytic activity, this paper describes the impact of Fusarium head blight (FHB) infection on the technological quality parameters of wheat flour and the dough’s rheological properties. The first treatment consisted of naturally grown, healthy wheat without fungicides, while the second treatment utilized wheat varieties subjected to intense FHB infection. Protein and wet gluten content in wheat grain and flour of uninfected cultivars were heavily influenced by testing location, soil type, and quality. Fusarium infection increased the activity of nonspecific proteases by 43% in flour samples from Osijek and 125% in flour samples from Tovarnik. Estimates of effect size showed that FHB infection had twice as big an effect on protease activity in Tovarnik as in Osijek, and a similar trend was found for dough softening. Moreover, the infection significantly impacted wheat cultivars’ extensograph values, indicating a lower resistance to stretching, extensibility, and total stretching energy in infected flour samples, indicating that dough functionality and volume loss can be attributed to exogenous fungal proteases. Still, the magnitude of the effect varied depending on the growth location and the cultivar’s traits. Multivariate data analysis identified three clusters of wheat cultivars, each with varying degrees of the Fusarium infection’s effects. Some cultivars displayed consistent protease activity and flour quality across sites. In contrast, others showed variability in their responses due to environmental conditions. To conclude, genetic resistance could provide adequate control of FHB, guaranteeing the successful protection of wheat quality. However, the possibility of confounding factors influencing genetic and cultivation conditions must be considered, and further research is needed to understand their interaction.
