Summary: The study focused on different tillage methods for faba bean cultivations, finding that air temperature and precipitation during the vegetative season had a greater impact on weed numbers than the types of tillage systems. Reduced tillage intensity did not lead to changes in weed numbers, which were mainly influenced by the volume of forecrop residues.

Summary: This study investigated the proteomic profile of developing faba bean seeds and found that proteins related to cell growth, division, and metabolism were most abundant in early growth stages, while seed storage proteins began to accumulate from 45 days after pollination. The relative abundance of seed proteins showed distinct temporal accumulation trends among protein classes.

Summary: This study aimed to saturate stable QTLs for ascochyta and broomrape resistance in two RIL populations by selecting candidate genes within the target intervals and exploiting synteny between faba bean and Medicago truncatula. The mapping process allowed the identification of promising candidate genes for resistance against the two pathogens, increasing genetic resolution of relevant QTL regions for marker-assisted breeding in faba bean. Further efforts in association mapping and expression studies will be required to validate these candidate genes for resistance.

Summary: The study evaluated the genetic variability of 14 Algerian faba bean accessions through agro-morphological traits and SSR markers, finding significant phenotypic variation and genetic diversity among accessions. The accessions were not clustered based on geographical pattern, and most of the genetic variation was due to differentiation among accessions. Additionally, there was no substantial correlation between molecular and agro-morphological traits. These findings suggest the potential for establishment of faba bean breeding programs in Algeria with optimal agro- and molecular diversity.

Summary: Faba bean is a cool-season grain legume crop grown worldwide for food and feed, with increasing interest due to its high seed protein content and ecological benefits. However, the crop faces various biotic and abiotic stresses, leading to unstable yields. Understanding resistance sources for diseases is crucial, but progress in abiotic stress tolerance is limited. Breeding efforts, though hindered by challenges, have shown promise with the use of DNA markers and marker-assisted selection to improve genetic gain and accelerate breeding progress.

Summary: This study investigated the isolation of plant protein using mild wet processing methods that avoid alkali/acid and thermal treatments to meet the growing demand for clean-label ingredients. The impact of different conditions on the isolation of faba bean protein concentrates/isolates was evaluated, and it was found that the water extraction method at 35 degrees Celsius resulted in higher protein contents compared to salt-based methods. The water-extracted isolates also had higher amino acid content and better protein quality due to the presence of albumins.

Summary: There is limited research on drought tolerance in faba bean, a globally important legume crop. In this study, a genome-wide association study was conducted using genetic polymorphisms throughout the faba bean genome, and 29 SNP markers associated with drought tolerance were identified. Three of these markers corresponded to uncharacterized proteins, indicating the presence of novel genes associated with drought tolerance in faba bean. These findings provide a foundation for future marker-assisted breeding in the crop.

Summary: This study highlights the role of salt priming in mitigating salt stress on faba bean. It was found that salt shock resulted in negative effects on growth, photosynthetic pigments, and yield, accompanied by increased generation of H2O2 and lipid peroxidation. However, priming with increasing concentrations of NaCl improved plant defense mechanisms, including enhanced expression of GSH-related genes, proline accumulation, and antioxidant enzymes, thereby reducing the detrimental effects of salt shock on growth and yield.

Summary: The study revealed that Pyrenophora teres f. teres induces host disease resistance genes and suppresses systemic acquired resistance genes during infection of barley with net form net blotch. Furthermore, it was found that host genes involved in defense-related thionin expression were absent during infection. Additionally, the research identified a number of P. teres f. teres effector genes with differing expression profiles that may contribute to barley sensitivity to net form net blotch.

Summary: Barley powdery mildew is a major disease that breeders have traditionally controlled using dominant, pathogen race-specific resistance genes. However, continuous selection pressure and pathogen mutation have led to the need for alternative solutions. Three novel major-effect adult plant resistance genes have been identified from landraces, offering opportunities for breeding programs to develop robust mildew resistance.

Summary: Fungal plant diseases are typically initiated by molecular interactions between effector molecules released by pathogens and receptor molecules on or within the plant host cell, with these interactions directly determining host resistance or susceptibility. A novel comparison method called RemEff is capable of identifying protein families with greater sensitivity than traditional homology-inference methods, enabling the prediction of novel fungal effector candidates through protein family association.

Summary: This study characterized 150 accessions of Spanish durum wheat collection and identified genetic regions on chromosome 2B that are involved in the control of stem traits and lodging tolerance in both durum and bread wheat. The study also highlighted the potential of these durum wheat landraces as donors for enhancing lodging tolerance and resistance to wheat stem sawfly. The identified marker-trait associations for stem-related traits could be used as a reference for further marker development.

Summary: Genomic prediction is used to predict breeding values based on molecular and phenotypic data. This study evaluated the performance of different models in predicting disease resistance in synthetic hexaploid wheat. The results showed that the combination of genomic and pedigree information (A+G BLUP) had the highest prediction accuracy, while the single trait and multi-trait models had similar accuracies. This suggests that the use of genomic information can improve breeding programs.

Summary: Gene expression analysis revealed that RBgh2 plays a role in cAMP/G-protein-coupled signalling and innate immunity in barley powdery mildew adult plant resistance. RBgh2 is a major effect adult plant resistance gene in barley powdery mildew, showing different underlying genetic factors compared to conventional resistance genes. The resistance mechanism of RBgh2 involves temporary genome-wide gene expression changes and constitutive changes, especially at the RBgh2 locus, inducing defence-related genes associated with innate immunity and pathogen recognition.

Summary: Spot form net blotch, caused by Pyrenophora teres f. maculata, is a major foliar disease of barley worldwide. The pathogen has high genetic diversity and a lack of population structure across Australia, indicating its high mobility and absence of geographical isolation or cultivar directional selection. However, two cryptic genotypic groups were found only in Western Australia, associated with fungicide resistance genes. These findings have implications for cultivar resistance and the adaptive potential of the pathogen.

However, a local isolate called M3 has gained virulence against a major susceptibility gene in Baudin, making it highly susceptible. This susceptibility gene, designated Spm1, maps to a 190-kb section of chromosome 1H.

Summary: In this study, somaclonal variation in Vanilla planifolia was induced by gamma radiation and detected using ISSR molecular markers. Results showed that low doses of radiation promoted development, while high doses inhibited growth and caused death. UBC-808, UBC-836, and UBC-840 primers exhibited the highest percentage of polymorphism. Genetic distance analysis revealed the presence of somaclonal variation in both irradiated and non-irradiated explants.
