Summary: This study reveals the critical role of FgNls1 in the pathogenesis of F. graminearum and suggests that host-induced gene silencing targeting F. graminearum effectors is a promising approach to enhance resistance to Fusarium head blight (FHB) in wheat.

Summary: The search for beneficial endophytes has been increasing in recent year. In this study, three endophytic fungi isolated from wheat were characterized for their antagonism against the Fusarium head blight pathogen. The results showed that these endophytes significantly increased seed weight and reduced mycotoxin accumulation. Investigation into the mechanism of competition revealed that the endophytes could competitively exclude the pathogen. The findings highlight the challenges in finding beneficial microbes for agriculture and call for a better understanding of the risks and ecological context.

Summary: The study in the main wheat production area of China found that climate factors, rather than cropping systems, had a greater impact on the relative prevalence of Fusarium graminearum and Fusarium asiaticum. Environmental conditions during the overwintering period appeared to be more important than those during other growth stages.

Summary: The study demonstrated the biocontrol efficacy of Metarhizium anisopliae against Fusarium graminearum causing Fusarium head blight in wheat. M. anisopliae inhibited F. graminearum mycelial growth and conidial germination, while also showing positive effects on wheat seedling growth and single-spike weight. Field experiments indicated significant control efficacy of M. anisopliae as a promising biocontrol agent against FHB in wheat.

Summary: Research has shown that the mycoparasite Sphaerodes mycoparasitica has a significant impact on the protein and lipid regions, with a connection between carbohydrates and protein regions, involving potential phenolic compounds. Through FTIR analysis, SEM and CLSM observation of fungus-fungus interactions, and PCA analysis, early mycoparasitism can be effectively detected as a vital strategy against plant pathogens.

Summary: In this study, the resistance genes Fhb1 and Fhb7 were introduced into the endophytic fungus Phomopsis liquidambaris to develop a new method for preventing and controlling Fusarium head blight in wheat. Preinoculation of wheat seedlings with PL-Fhb1 and PL-Fhb7 increased the resistance against deoxynivalenol (DON) and inhibited the growth of F. graminearum. The incidence rates of diseased spikes and the levels of DON in wheat grains were significantly reduced when preinoculating leaves with PL-Fhb1 and PL-Fhb7 or inoculating wheat flowers with PL-Fhb1 and PL-Fhb7 followed by F. graminearum infection. Furthermore, PL-Fhb7 was found to transform DON into DON-glutathione using HPLC-MS. This study highlights the potential of engineered endophytes for improving resistance to Fusarium head blight and presents a new approach for biological control.

Summary: This study first reported that hydrogen sulphide (H2S) can significantly alleviate the symptoms of FHB in wheat caused by F. graminearum. H2S enhances FHB resistance by reducing oxidative stress and upregulating defence-related gene expression. In addition, H2S exhibits toxic effects on F. graminearum, inhibiting its growth and spore germination.

Summary: A study was conducted at CIMMYT in Mexico and in southern and northern Italy to test the Fusarium head blight (FHB) susceptibility of 35 Italian durum wheat cultivars, with 16 cultivars re-tested in the 2019-20 cropping season. The majority of tested cultivars were found to be susceptible to FHB, with the exception of a few moderately susceptible ones. Factors contributing to this difference in susceptibility included plant height and flowering biology.

Summary: This study demonstrates that treatment with the methanolic extract of Zanthoxylum bungeanum can reduce the growth of F. graminearum and inhibit the production of deoxynivalenol. The extract is mainly composed of four flavonoids. In vitro bioassays show that the extract can inhibit fungal growth. After biocontrol treatment, the levels of F. graminearum DNA and deoxynivalenol were reduced.

Summary: In this study, the QTL associated with resistance to wheat head blight caused by Fusarium verticillioides (F.v) were mapped using genotype data from a population of 262 recombinant inbred lines (RILs) derived from Zhongmai 578 and Jimai 22. A total of 22 QTL were identified, with one novel QTL and one stable QTL detected. Forty-seven candidate genes related to disease resistance were found in the interval of the QTL. Genomic prediction accuracies for the disease traits were estimated using the cross-validation scheme.

Summary: This study evaluated the aggressiveness of F. cerealis to durum wheat cultivars and mycotoxin production in planta, finding that all cultivars exhibited typical FHB symptoms and NIV was the most produced mycotoxin. Molecular analysis revealed all strains possessed NIV genotype, while chemical assessment showed they could produce various secondary metabolites. The increasing incidence of F. cerealis and the potential crop contamination with mycotoxins pose great concern for food security and world cereal trade, especially given the higher toxicity of NIV compared to DON.

Summary: This study conducted a genetic analysis of the head blight pathogen in wheat-producing regions of India, revealing the presence of multiple haplotypes and genetic variations. The genetic diversity was found to be primarily driven by differences within populations. The population structure of the pathogen in Punjab showed evidence of a balancing selection mechanism.

Summary: Maize brown sheath spot (MBSS) is a newly discovered disease on maize in India. It is caused by a fungus called Waitea circinata var. prodigus, which is known to cause basal leaf blight of seashore paspalum. The symptoms of MBSS are discrete lesions on the sheaths of maize plants. Further investigations are needed to understand the geographical distribution and potential impacts of MBSS on the maize crop in India.

Summary: Efficient cross-pollination and an improved male sterility system are required for breeding hybrids with maximum heterosis. This study investigated the genetic basis and impact on seed setting of hybrid floral traits in elite wheat genotypes crossed using a chemical hybridizing agent. The results showed a strong correlation between seed set and pollen mass, visual anther extrusion, and pollen shedding. The study also identified the range of heterosis for biomass, thousand kernel weight, and grain yield in both mid-parent and best-parent heterosis. The findings suggest that selecting parents based on their general combining ability could be an effective approach for achieving high heterosis.

Summary: This study evaluated the inheritance of the high-phosphate (HIP) phenotype in wheat and identified two major-effect quantitative trait loci (QTL) that contribute to this phenotype. Synergistic additive x additive epistasis was found between these QTL. Ten candidate genes associated with the phenotype were identified, of which five encode proteins involved in inositol phosphate metabolism. Site-specific marker assays were developed for marker-assisted breeding.

Summary: Hybrid wheat has the potential to yield more than conventional inbred cultivars, but the production cost of hybrid seed needs to be minimized for commercial success. This research identified anther extrusion, pollen 50 date, plant height, and pollination duration as the most important traits for hybrid seed production. These traits varied among genotypes and showed significant differences among years, but consistent performance patterns were observed.

Summary: Common bunt is a major wheat disease that causes significant damage to grain yield and quality in the USA and Turkey. Although seed treatment with fungicides is an effective control method, it is forbidden in organic and low-income fields, leading to a preference for planting resistant cultivars. The use of fungicides has resulted in limited efforts to breed resistant genotypes, and the genetic diversity for this trait is low in modern wheat germplasm. However, synthetic wheat genotypes have been found to be an effective source of increasing diversity in wheat germplasm.

Summary: With the advances in DNA markers, KASP markers have the potential to accelerate breeding programs and improve drought tolerance. In this study, two previously reported KASP markers, TaDreb-B1 and 1-FEH w3, were investigated for marker-assisted selection of drought tolerance. The results showed that TaDreb-B1 marker provided better consistency in improving drought tolerance than 1-FEH w3.
