Background/Objectives: The phytosulfokine receptor (PSKR) gene family plays a crucial role in regulating plant growth, development, and stress response. Here, the PSKR was characterized Triticum aestivum L. study aimed to bridge knowledge gaps clarify functional roles of TaPSKRs create solid foundation for examining structure, functions, regulatory aspects. Methods: investigation involved genome-wide identification PSKRs through collection chromosomal assignment, followed by phylogenetic analysis expression profiling. Additionally, interactions with their interactors were stimulated analyzed elucidate function. Results: wide-genome inspection all led 25 genes various homeologs, resulting 57 TaPSKR members distributed among A, B, D subgenomes. Investigating 61 cDNAs RNA-seq datasets generated from different growth stages at 14, 21, 60 days old diverse tissues such as leaves, shoots, roots provided further insight into purposes. profile resulted three key clusters. Gene cluster 1 (GC 1) is partially associated root suggesting that specific control development. GC 2 targeted show high levels tested leaf early developmental stage shoots roots. Furthermore, 3 composed are constantly expressed, highlighting processes during entire life cycle wheat. Molecular docking simulations showed type α (PSK-α) interacted had strong binding affinity certain proteins, encompassing TaPSKR1A, TaPSKR3B, TaPSKR13A, support involvement PSK signaling pathways. arbitration may depend on between wheat PSK-α PSKRs, especially LRR domain region.

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.

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.

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.

Abstract DNA methylation plays important roles in gene expression, transposable element silencing, and genome stability. Altering could generate additional phenotypic variation for crop breeding, however the lethality of epigenetic mutants species has hindered its investigation. Here, we exploit partial redundancy between homoeologues polyploid wheat to viable methyltransferase 1-1 (MET1-1) with altered profiles. In Triticum turgidum (tetraploid wheat) aestivum (hexaploid wheat), found under-representation higher order (5/6 6/6 mutant met1-1 copies hexaploid 3/4 4/4 tetraploid when genotyping segregating seeds seedlings, due reduced transmission null gametes from paternal maternal side. The loss four or more functional MET1-1 results decreased CG wheat. Changes expression increase stepwise number alleles, suggesting a dosage-dependent effect. We identified heritable changes flowering awn phenotypes which segregate independently MET1-1. Together our demonstrate that polyploidy can be leveraged quantitative without lethal consequences observed other crops.
