Summary: The study on bacterial spot in bell and chili peppers revealed that hybrids containing resistance genes Bs2 and Bs1-2-3 tend to have lower disease incidence and higher yields. Copper spray programs can reduce disease and increase yield, but the results may not always be significant. Despite the breakdown of Bs2 resistance, hybrids with Bs2 resistance did not have reduced yields.

Summary: This study investigated the race composition of Pyrenophora tritici-repentis (Ptr) responsible for tan spot disease in Kazakhstan. The analysis showed that the Ptr isolates in Kazakhstan belonged to four known races and one potential atypical race. Races 1 and 2 were identified as critical for wheat production in Kazakhstan.

Summary: The objective of this study was to map the bs5 and bs6 loci in the pepper genome. Through crossing experiments, segregating populations were developed for bs5 and bs6, and their fine mapping showed that bs5 is located within a 535 Kbp interval on chromosome 3, and bs6 is located within a 666 Kbp interval on chromosome 6. By analyzing predicted protein coding polymorphisms, 14 candidate resistance genes for bs5 and 8 candidate resistance genes for bs6 were identified. This research enhances marker-assisted selection and provides insight into the molecular mechanisms underlying these resistances.

Summary: Nucleotides (p)ppGpp play important roles as signaling molecules in bacteria and plants. In this study, the researchers used CE-MS to analyze the abundance and composition of ppGpp in Arabidopsis thaliana and found a significant increase of ppGpp levels upon infection with the bacteria pathogen Pseudomonas syringae pv. tomato (PstDC3000), stimulated by the flagellin peptide flg22. This increase is dependent on the functional flg22 receptor FLS2 and its interacting kinase BAK1, indicating that PAMP receptor-mediated signaling controls ppGpp levels.

Summary: Bacteriophages were obtained from soil and tomato leaves in Brazil for use as biological control agents against bacterial spot. These phages showed potential in reducing disease severity in susceptible bacterial isolates, with efficacy similar to or greater than copper hydroxide. Phylogenetic analysis revealed that these phages belong to the genus Pradovirus and potentially represent a new species.

Summary: The high resistance level of Ae. tauschii accession CIae8 to Pm was identified and characterized. Inheritance analysis and gene mapping revealed that the resistance was controlled by two independent recessive genes. Molecular markers closely linked with the resistance loci were developed, laying the foundation for cloning the resistance genes and transferring them into common wheat.

Summary: The study evaluated the resistance of 42 wheat monogenic lines and 69 wheat cultivars to three new races of wheat stem rust. It was found that monogenic lines with certain Sr genes and SrTt3 gene were resistant to all three races, while lines with other Sr genes were highly susceptible. Some lines exhibited varying levels of resistance. Molecular marker analysis revealed the presence of specific Sr genes in certain wheat cultivars. These findings provide a scientific basis for the utilization of Sr genes and wheat cultivars.

Summary: This study found that previously proposed NBS-ARC genes contributing to Pc5.1 did not show significant response to P. capsici infection, and there were no significant differences in transcription levels between 305R and 372S. Other pathogen defense-related genes such as SN1 may account for Pc5.1. The study also proposed the important role of sugar and epigenetic regulation in defense against P. capsici.

Summary: The study aimed to evaluate the genetic diversity of 215 common bean accessions, revealing wide variability in morpho-agronomic and biochemical traits. Genetic parameters showed high to intermediate heritability for most traits, and Ward's hierarchical clustering analysis grouped the accessions into six clusters. AFLP analysis also indicated significant differences among the accessions, with no correlation between genetic markers and morpho-agronomic data, highlighting the importance of both datasets in understanding accession differences.

Summary: This study investigated common bean farmers in the state of Rio de Janeiro, Brazil, finding a wide variety in the number of bean varieties managed by families due to socioeconomic, ecogeographic, and cultural factors. Climate change has affected traditional agriculture in certain regions, leading to a decrease in common bean diversity. Efforts are being made to strengthen the conservation of local germplasm and promote self-consumption cultures for food security and preservation of cultural traditions.

Summary: This study focused on the identification and characterization of Colletotrichum spp. causing anthracnose, a major disease in pepper crops in Rio de Janeiro state. Through morpho-cultural, sequencing, and genetic variability analysis, all isolates were identified as Colletotrichum scovillei. Pathogenicity testing on Capsicum baccatum revealed stage-specific responses, with higher resistance in ripe fruits, and identified potential resistance sources among tested accessions. This data could contribute to future research on the interaction between Colletotrichum scovillei and Capsicum spp., a topic that has not been extensively explored.

Summary: The study evaluated nine okra landraces based on agronomic and biochemical traits, highlighting UEL7 for its high levels of biochemical traits and UEL3 for its strong agronomic performance despite lower biochemical traits. These findings suggest that UEL7 and UEL3 may be suitable for breeding programs focused on enhancing both human food nutrition and agronomic performance, while also contributing to okra germplasm conservation.
