This five-year study (2016–2021) in Morocco’s Mediterranean climate investigated the effect of nitrogen fertilization and genotypic selection on wheat yield associated components. Utilizing a split-plot design, assessed five genotypes—’Faraj’, ‘Luiza’, ‘Itri’, ‘Karim’ ‘Nassira’—under three application rates (120, 60 0 kg/ha) across thirty plots with two replicates. Interactions between year showed marked significance (p = 0.001), biomass 0.002), TKW 0.003) Spk/m2 underscoring variability optimal different years. Additionally, significant interactions variety were observed for 0.001) G/m2 indicating performance varieties The ‘Itri’ genotype highest 2017, while ‘Luiza’ was pre-eminent 2018, producing most biomass. ‘Faraj’ demonstrated consistent superiority during 2019 2020. Our integrated principal component analysis quadratic models elucidated that an intermediate rate kg/ha (N2) particularly advantageous genotypes. These findings highlight substantial impact informed level adjustment optimization.

Identifying traits for improving sink strength is a bottleneck to increasing wheat yield. The interacting processes determining and yield potential are reviewed visualized in set of 'wiring diagrams', covering critical phases development (and summarizing known underlying genetics). Using this framework, we assembled the main identified research gaps hypotheses be tested achieving gains strength. In pre-anthesis, grain number could increased through: (i) enhanced spike growth associated with optimized floret and/or reduction specific stem-internode lengths (ii) improved fruiting efficiency through an accelerated rate development, partitioning between spikes, or cytokinin levels. post-anthesis, grain, augmented manipulation size via ovary endosperm cell division expansion. Prospects vascular architecture support all rapidly growing florets, enabling flow assimilate, also discussed. Finally, considered prospects enhancing weight realization relation genetic variation stay-green as well stem carbohydrate remobilization. wiring diagrams provide workspace breeders crop scientists achieve other field crops.

Plant height is an important agronomic trait with a significant impact on grain yield, as demonstrated by the positive effect of REDUCED HEIGHT (RHT) dwarfing alleles (Rht1b) lodging and harvest index in "Green Revolution" wheat varieties. However, these gibberellic acid (GA)-insensitive also reduce coleoptile length, biomass production, yield potential some environments, triggering search for alternative GA-sensitive genes. Here we report identification, validation, characterization gene underlying locus RHT25 wheat. This gene, designated PLATZ-A1 (TraesCS6A02G156600), expressed mainly elongating stem developing spike encodes plant-specific AT-rich sequence- zinc-binding protein (PLATZ). Natural induced loss-of-function mutations plant its overexpression increases height, demonstrating that causative RHT25. RHT1 show genetic interaction their encoded proteins interact each other yeast protoplasts. These results suggest PLATZ1 can modulate DELLA height. We identified four natural truncation one promoter insertion are more frequent modern varieties than landraces, suggesting selection during breeding. be used to fine-tune and, combination genes, replace GA-insensitive Rht1b improvements beyond those Green Revolution

Wheat is the most widely grown crop globally, providing 20% of daily consumed calories and protein content around world. With growing global population frequent occurrence extreme weather caused by climate change, ensuring adequate wheat production essential for food security. The architecture inflorescence plays a crucial role in determining grain number size, which key trait improving yield. Recent advances genomics gene cloning techniques have improved our understanding spike development its applications breeding practices. Here, we summarize genetic regulation network governing formation, strategies used identifying studying factors affecting architecture, progress made applications. Additionally, highlight future directions that will aid regulatory mechanistic study determination targeted yield improvement.

Tillering is a critical agronomic trait of wheat (Triticum aestivum L.) that determines the shoot architecture and affects grain yield. TERMINAL FLOWER 1 (TFL1), encoding phosphatidylethanolamine-binding protein, implicated in transition to flowering plant development. However, roles TFL1 homologs little known CRISPR/Cas9-mediated targeted mutagenesis was used this study generate set (Fielder) mutants with single, double or triple-null tatfl1-5 alleles. The mutations decreased tiller number per vegetative growth stage effective spikelet spike at maturity field. RNA-seq analysis showed expression auxin signaling-related cytokinin genes significantly changed axillary buds mutant seedlings. results suggested TaTFL1-5s were regulation by signaling.

Large-scale genotype-phenotype association studies of crop germplasm are important for identifying alleles associated with favorable traits. The limited number single-nucleotide polymorphisms (SNPs) in most wheat genome-wide (GWASs) restricts their power to detect marker-trait associations. Additionally, only a few genes regulating grain per spikelet have been reported due sensitivity this trait variable environments.We perform large-scale GWAS using approximately 40 million filtered SNPs 27 spike morphology We 132,086 significant associations and the SNP markers located within 590 peaks. additional stronger peaks by dividing into sub-traits relative results propose that genetic dissection is powerful strategy signals yield traits wheat. reveal TaSPL17 positively controls size floret meristem development, which turn leads enhanced plant. haplotypes at indicate geographical differentiation, domestication effects, breeding selection.Our study provides valuable resources improvement fast-forward solution candidate gene detection cloning

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.
