Summary: Two novel alleles of Vrn-A1, vrn-A1n and Vrn-A1o, were discovered in Chinese cultivars, with vrn-A1n found in two landraces and vrn-A1o detected in Duanhongmangmai. Both alleles showed a linked duplication in the promoter region, and the common copy was identical to the recessive allele vrn-A1. Plants with vrn-A1n did not head earlier than those with vrn-A1 under nonvernalizing and long-day conditions, while plants with Vrn-A1o headed earlier than those with vrn-A1.

Summary: The study found that Canadian wheat genotypes exhibit higher resistance to tan spot, while European wheat genotypes show lower resistance. The presence of the ToxA-sensitive gene Tsn1 is more common in Canadian wheat genotypes, but not all durum genotypes carrying Tsn1 are susceptible to ToxA-producing isolates.

Summary: The study investigated the pathogenicity profiles of an Australian population of Parastagonospora nodorum using a diverse wheat panel, identifying distinct resistance patterns and isolate-specific quantitative trait loci (QTL). The study also discovered active interactions between SnTox3 haplotypes and Snn3-B1 and Snn3-D1 in Australian and bread wheat for the first time, potentially due to the use of new SnTox3 variants and germplasm from CIMMYT/ICARDA and Vavilov. These findings could contribute valuable information for SNB resistance breeding programs by dissecting novel disease components and identifying genetic markers.

Summary: Leaf blight diseases, such as Septoria nodorum blotch and tan spot, are becoming more prevalent in northern parts of India due to changing climate conditions. A study on 296 bread wheat cultivars released in India over the past two decades identified novel genetic markers associated with resistance to these diseases. The findings provide valuable information for future wheat improvement programs.

Summary: The study revealed that the microbial community composition and network characteristics in the roots and rhizosphere of resistant wheat cultivars play a significant role in plant disease resistance, showing higher microbial diversity and stable community structure. Resistant cultivars recruit more beneficial microbial groups while susceptible cultivars have higher relative abundance of potential pathogens.

Summary: In this study, the presence of stem rust resistance genes in 65 commercial wheat cultivars from Hebei Province was determined using gene postulation, pedigree analysis, and molecular detection. The results revealed the presence of 6 Sr genes (Sr5, Sr17, Sr24, Sr31, Sr32, Sr38, and SrTmp) in 46 wheat cultivars, with Sr31 being the most common. This study is important for breeding wheat cultivars resistant to stem rust.

Summary: Transcriptomic analyses of developing wheat anthers under heat stress identified key genes involved in hormone biosynthesis, signal transduction, heat shock response, and anther development. Heat stress disrupted pollen development in heat-sensitive wheat cultivars but had no visible effect on heat-tolerant cultivars, leading to reduced grain yield in sensitive cultivars. Genes identified in this study may serve as potential molecular markers for breeding heat-tolerant wheat lines.

Summary: Potential mechanisms of ZM168 grain quality were unveiled through RNA-seq and PacBio full-length sequencing technology. A total of 44,709 transcripts were identified in Y13N and 51,942 transcripts in Z168N, including 28,016 and 28,626 novel isoforms in Y13N and Z168N, respectively. Five hundred and eighty-four differential alternative splicing events and 491 long noncoding RNAs were discovered. New candidates associated with SSV have emerged, including 4 transcription factors and 11 transcripts involved in the post-translational modification pathway. The transcriptome atlas provides new perspectives on wheat grain quality and would benefit breeding programs.

Summary: The effector SnTox3 interacts with wheat pathogenesis-related protein 1 (TaPR-1) and influences its function by inhibiting the release of TaCAPE1, therefore activating host defense mechanisms. SnTox3 also independently induces necrosis and suppresses host defense, showcasing its dual functionality in disease development.

Summary: Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici, is a major economically important disease of wheat. Recent research has identified gene-for-gene interaction factors between Z. tritici and wheat, namely the wheat receptor-like kinase Stb6 and the Z. tritici secreted effector protein AvrStb6. Studies show a high diversity of AvrStb6 haplotypes in earlier Z. tritici isolates, but a complete absence of the avirulence isoform among modern isolates, indicating a trend towards elimination of avirulence haplotypes in subsequent Z. tritici populations.

Summary: Plant pathogens cause disease by secreting effector proteins, which require further targeted experimentation for functional studies. Research on SnTox3 using a structure/function approach revealed a novel beta-barrel fold and identified residues essential for Snn3 recognition through structure-guided mutagenesis. Additionally, a conserved motif (LxxR) in the pro-domain of fungal effectors, which can be cleaved by the protease Kex2, was discovered in an expanded set of effectors through in silico analysis.

Summary: Plant fungal pathogens produce protein effectors that promote disease, with some inducing cell death responses in plants. Traditional microbial expression systems may not be suitable for fungal effectors with specific requirements. A simple and efficient method for expressing these effectors in the model plant Nicotiana benthamiana is described, allowing for high-throughput phenotyping on host plants.
