“…The disease is expanding rapidly in many regions. A good example is China, where the epidemic area has expanded to major wheat production regions, including the Yellow and Huai River valley wheat zones and the northern winter wheat zone, because of the lack of resistant cultivars and an increase in acreage with no-tillage cultivation and maize-wheat rotation (116). Early FHB infections around anthesis often cause floret sterility or poor grain filling, leading to higher yield losses, whereas later infections could have low yield impacts but may lead to high DON content (12).…”

Wheat is grown worldwide in diverse geographical regions, environments, and production systems. Although many diseases and pests are known to reduce grain yield potential and quality, the three rusts and powdery mildew fungi have historically caused major crop losses and continue to remain economically important despite the widespread use of host resistance and fungicides. The evolution and fast spread of virulent and more aggressive race lineages of rust fungi have only worsened the situation. Fusarium head blight, leaf spotting diseases, and, more recently, wheat blast (in South America and Bangladesh) have become diseases of major importance in recent years largely because of intensive production systems, the expansion of conservation agriculture, undesirable crop rotations, or increased dependency on fungicides. High genetic diversity for race-specific and quantitative resistance is known for most diseases; their selection through phenotyping reinforced with molecular strategies offers great promise in achieving more durable resistance and enhancing global wheat productivity.

“…With increase in global warming, particularly with rising of minimum winter temperatures (Ziska 2014) and heavier rainfall during the anthesis period, the disease has been considerably expanding worldwide (Chakraborty and Newton 2011), severely affecting various provinces throughout China (Lu and Chen 2012;Zhang et al 2014), North American (Ward et al 2008) and European (Miraglia et al 2009) countries, as well as the Southern Cone region of South America (Kohli and Díaz de Ackermann 2013).…”

A novel assembly of Thinopyrum ponticum genes into the durum wheat genome: pyramiding Fusarium head blight resistance onto recombinant lines previously engineered for other beneficial traits from the same alien species

Favoured by climate changes, Fusarium head blight (FHB) has recently become a threat also in unusual environments, including those where durum wheat is largely cultivated. Since current durum wheat cultivars are mostly susceptible to FHB, new germplasm is needed, capable of maintaining yield capacity and grain quality under the disease pressure. To achieve this goal, a sustainable approach relies on transfer of resistance from related Triticeae species by means of chromosome engineering. We resorted to this cytogenetic strategy, efficiently complemented with advanced selection systems, to transfer into durum a QTL for FHB resistance (here, temporarily designated Fhb-7el 2 ) previously mapped on the 7el 2 L arm of the wild Thinopyrum ponticum. A bread wheat 7DS.7el 2 L translocation line was employed as donor of Fhb-7el 2 in crosses with previously developed durum wheat 7AS.7AL-7el 1 L recombinant genotypes, carrying genes for rust diseases (Lr19 ? Sr25) as well as for quality-and yieldcontributing traits, deriving from a different Th. ponticum accession. In pentaploid F 1 s, the largely homologous 7el 1 L and 7el 2 L arms showed considerable reduction in pairing and recombination frequency as compared to what observed in a parallel experiment we carried out in a hexaploid context. Nevertheless, pyramiding into durum of target genes/QTL from the two Th. ponticum accessions was successfully achieved. The selected 7el 1 L ? 7el 2 L tetraploid lines exhibited 70-85 % reduction in FHB severity following Fusarium inoculation, and a parallel decrease in fungal biomass in kernels of infected spikes. Similar effects were detected in bread wheat lines carrying the same target gene assembly on 7DL instead of 7AL. Preliminary evidence of good agronomic performance of the novel 7el 1 L ? 7el 2 L recombinant lines paves the way for their straightforward exploitation in breeding.

“…The estimation of incidence of wheat FHB in central China was evaluated by developing a logistic weather-based regression model, using up to 10 years (2001-2010) of disease, anthesis date, and weather data available for 10 locations in Anhui and Hubei provinces. How climate change may affect wheat anthesis date and FHB in central China was estimated for the period 2020-2050 using the wheat growth model Sirius and simulated weather data obtained employing the regional climate modelling system PRECIS [77]. The study suggested that climate change will increase the risk of serious FHB epidemics on winter wheat in central China by the middle of this century, as also predicted for the UK by Madgwick et al [76].…”

“…A relevant study outside Europe was carried out by Zhang et al [77] and investigated the impacts on FHB on wheat in China due to climate change. The estimation of incidence of wheat FHB in central China was evaluated by developing a logistic weather-based regression model, using up to 10 years (2001-2010) of disease, anthesis date, and weather data available for 10 locations in Anhui and Hubei provinces.…”

“…The implications for food security in China are extremely serious, because FHB is already a cause of substantial losses in wheat yield and quality, exacerbated by the high level of Fusarium mycotoxin accumulation in the kernels [77]. Because wheat is an essential staple crop over large areas of China, these predicted impacts of climate change would provide a guide to the Chinese government and industry in preparation for adaptation to climate change [77].…”
