Abstract Key message Sedimentation values and falling number in the last decades have helped maintain high baking quality despite rigorous selection for grain yield wheat. Allelic combinations of major loci sustained bread-making while improving yield. Glu-D1 , Pinb-D1 non-gluten proteins are associated with sedimentation European Zeleny (ZSV) Hagberg-Perten (HFN) among most important parameters that help determine classes wheat and, thus, influence monetary benefits growers. We used a published data set 372 varieties evaluated replicated field trials multiple environments. ZSV HFN traits hold wide significant genotypic variation broad-sense heritability. The genetic correlations revealed positive associations each other, protein content (GPC) hardness; however, they were all significantly negatively correlated Besides, GPC appeared to be predictor HFN.

Photoperiod insensitivity has been selected by breeders to help adapt crops diverse environments and farming practices. In wheat, insensitive alleles of Photoperiod-1 (Ppd-1) relieve the requirement long daylengths flower promoting expression floral genes early in season; however, these also limit yield reducing number fertility grain-producing florets through processes that are poorly understood. Here, we performed transcriptome analysis developing inflorescence using near-isogenic lines contain either photoperiod-insensitive or null Ppd-1, during stages when spikelet is determined floret development initiates. We report Ppd-1 influences stage-specific with roles auxin signaling, meristem identity, protein turnover, differentially expressed transcripts identified bZIP ALOG transcription factors, namely PDB1 ALOG1, which regulate flowering time architecture. These findings enhance our understanding introduce new targets for improving potential.

Continuing to raise the potential yield of wheat through breeding is essential for global food security. Past progress has largely been associated with greater grains/m2 (GN), critical period determination which relates spike growth, GN often closely related dry weight at anthesis (g/m2). This focussed review outlines importance duration (Ds, in days or °Cdays) and questions how it may be increased genetically, relying partly on long involvement authors this field, primarily lower latitude crops spring-type wheat. Ds further defined as interval between flag leaf emergence first anthesis, each across 50 % culms any crop, a encompassing most accumulation matter, turn determining floret survival final fertile numbers/m2. Natural temperature variation manipulation, particularly field crops, confirm dependence temperature, °Cdays varies from about 300–500, depending photoperiod. Evidence points stronger influence night than day Ds, while maintaining close positive relationship GN. However, genetic response appears very minor. inversely photoperiod, again expected effects weight, florets Extended photoperiod during showed greatest reduction per advance anthesis. responses can major sensitivity alleles present. A experiment unique reduced treatment demonstrated strong effect GN, especially fully recessive photoperiod-sensitive isoline. While more recent varieties tend have longer experiments targeting selection intervals delivered little change low heritability. Field shortening studies needs testing proof concept. Better are also needed. At same time, knowledge molecular basis such that gene editing surely ripe tackle challenge down-regulating only period, thereby increasing Exogenous application plant development regulators appropriate stage provide way forward.

Context Several high-quality reference genomes for oat (Avena sativa L. and relatives) have been published, with the prospect of many additional whole-genome assemblies emerging in near future. Aims This has necessitated an effort by International Oat Nomenclature Committee (IONC; all co-authors on this paper) to devise a universal system naming subgenomes, chromosomes, genes, gene models quantitative trait loci. Methods We evaluated existing practices, recent data from sequencing, newly published convention wheat nomenclature. Key results A framework these rules posted GrainGenes database website (https://wheat.pw.usda.gov/GG3/oatnomenclature). The requires adoption numerical identifier each genotype; we propose that identifiers be assigned contacting curators, curator Newsletter, or member IONC (as listed at link above). Conclusions encourage researchers refer resources, policies, procedures conventions, adopting them as international nomenclature standard. Implications Adoption standards will facilitate communication dissemination research allow programmatic access sharing across platforms, contribute breeding worldwide.

Rapid climate changes, with higher warming rates during winter and spring seasons, dramatically affect the vernalization requirements, one of most critical processes for induction wheat reproductive growth, severe consequences on flowering time, grain filling, yield. Specifically, Vrn genes play a major role in transition from vegetative to growth wheat. Recent advances genomics have significantly improved understanding molecular mechanisms (Vrn-1, Vrn-2, Vrn-3, Vrn-4), unveiling diverse array natural allelic variations. In this review, we examined current knowledge functional structural point view, considering studies conducted alleles at different ploidy levels (diploid, tetraploid, hexaploid). The characterization Vrn-1 has been focal point, revealing forms implications time. We highlighted complexity problems linked nomenclature some alleles. Addressing these issues will be crucial harmonizing research efforts enhancing our gene function evolution. increasing availability genome transcriptome sequences, along improvements bioinformatics computational biology, offers versatile range possibilities enriching genomic regions surrounding target sites genes, paving way innovative approaches manipulate time improve productivity.

Abstract Agro‐morphological traits play a significant role in the adaptation of wheat to diverse agroecosystems. Genetic understanding these is crucial develop cultivars adapted specific environments and maximize their productivity. This comprehensive genome‐wide association study (GWAS) 230 lines soft red winter for identifying quantitative trait loci (QTLs) related eight key agro‐morphological traits. The diversity panel was evaluated two locations three consecutive years (2020–2023). A total 150 marker–trait associations were detected, including 65 flag leaf traits, 35 peduncle length, 33 plant height, 16 heading date, one vigor using 27,466 single nucleotide polymorphism (SNP) markers. Eleven high‐confidence major‐effect QTLs explaining greater than 10% phenotypic variance which seven stable, showed an with height length. possibly allelic important dwarfing ( Rht23 ) vernalization Vrn‐B1 genes identified.

Fusarium head blight (FHB), caused by graminearum, is a globally significant disease that severely impacts the yield and quality of wheat. Breeding resistant wheat varieties using resistance genes most cost-effective strategy for managing FHB, but few markers are available marker-assisted selection (MAS) resistance. In this study, we evaluated recombinant inbred line (RIL) population to FHB through single-floret inoculation in four field environments over two years. Combined with quantitative trait loci (QTL) detection high-density genetic mapping based on 50 K SNP arrays, identified total 21 QTLs influencing It worth noting QFhba-5D.2-1 was detected as well multi-environment trial (MET) analysis, explaining phenotypic variation ranging from 1.98% 18.55%. We also pinpointed thirteen within QTL intervals chromosomes 4A, 5D, 6B, 7A associated defense mechanisms. Furthermore, developed Kompetitive Allele-Specific PCR (KASP) QFhba-7A regions validate their specificity RIL population. Subsequently, validated polymorphism these 305 germplasms analyzed effect thousand kernel weight (TKW) spike length (SL). These will accelerate development FHB-resistant MAS, significantly reducing losses strengthening food security.
