Genetic dissection of yield-related traits can be used to improve wheat yield through molecular design breeding. In this study, we genotyped 245 varieties and measured 13 plant height-, grain-, spike-related traits, in seven environments, identified 778 loci for these by genome-wide association study (GWAS) using single- multi-locus models. Among loci, nine were major, which novel, including Qph/lph.ahau-7A height (PH) leaf pillow (LPH), Qngps/sps.ahau-1A number grains per spike (NGPS) spikelet (SPS), Qsd.ahau-2B.1 Qsd.ahau-5A.2 density (SD), Qlph.ahau-7B.2 LPH, Qgl.ahau-7B.3 grain length (GL), Qsl.ahau-3A.3 (SL). Through marker development, re-GWAS, gene annotation cloning, sequence variation, haplotype, expression analyses, confirmed two novel major potential candidate genes, TraesCS7A02G118000 (named TaF-box-7A) TraesCS1A02G190200 TaBSK2-1A) underlying PH-related traits. We also reported favorable haplotypes, TaF-box-Hap1 associated with low PH LPH TaBSK2-Hap3 high NGPS SPS. summary, findings applied enrich our understanding the complex genetic mechanisms

Common wheat (Triticum aestivum) is one of the most widely cultivated and consumed crops globally. In face limited arable land climate changes, it a great challenge to maintain current increase future production. Enhancing agronomic traits in by introducing mutations across all three homoeologous copies each gene has proven be difficult task due its large genome with high repetition. However, clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated nuclease (Cas) editing technologies offer powerful means precisely manipulating genomes crop species, thereby opening up new possibilities for biotechnology breeding. this review, we first focus on development optimization CRISPR-based tools wheat, emphasizing recent breakthroughs precise multiplex editing. We then describe general procedure highlight different methods deliver reagents into cells. Furthermore, summarize applications advancements CRISPR/Cas improvement. Lastly, discuss remaining challenges specific prospects.

SUMMARY Spike architecture is a critical determinant of grain yield in wheat; yet the regulatory mechanisms remain poorly understood. Here, we demonstrate that AP2 transcription factor Q directly represses expression TaMYB30‐6A , gene associated with spike length wheat. We further identify QIP3 as Q‐interacting protein harboring an N‐terminal EAR motif. Simultaneously, reveal exhibits transcriptional repression activity, dependent on motif, and physically interacts corepressor TaTPL. Importantly, clustered regularly interspaced short palindromic repeats/CRISPR‐associated 9 (CRISPR/Cas9)‐generated qip3‐aabbdd mutants exhibit reduced plant height increased phenotypes. Furthermore, RNA‐seq RT‐qPCR assays show negatively regulates target Collectively, propose motif‐containing to regulate by recruiting TaTPL

Climate change is a global concern for agriculture, food security, and human health. It affects several crops causes drastic losses in yield, leading to severe disturbances the economy, environment, community. The consequences on important staple crops, such as rice, maize, wheat, will worsen create insecurity across globe. Although various methods of trait improvements are available being used, clustered regularly interspaced short palindromic repeats CRISPR-associated protein 9 (CRISPR/Cas9) mediated genome manipulation have opened new avenue functional genomics crop improvement. This review discuss progression improvement from conventional breeding advanced editing techniques how CRISPR/Cas9 technology can be applied enhance tolerance main cereal (wheat, maize) against any harsh climates. CRISPR/Cas endonucleases their derived genetic engineering tools possess high accuracy, versatile, more specific, easy design, climate-smart or resilient combat survive environments.
