Abstract: Grain size and weight are important components of a suite of yield-related traits in crops. Here, we showed that the CRISPR-Cas9 gene editing of TaGW7, a homolog of rice OsGW7 encoding a TONNEAU1-recruiting motif (TRM) protein, affects grain shape and weight in allohexaploid wheat. By editing the TaGW7 homoeologs in the B and D genomes, we showed that mutations in either of the two or both genomes increased the grain width and weight but reduced the grain length. The effect sizes of mutations in the TaGW7 gene… Show more

“…In addition to protecting crops from pathogens and weed, genome editing helped to raise mutants with high grain productivity per plant in wheat. Wang, Pan, et al (2019) reported mutation in TaGW7 homoeologs in the B and D genome of hexaploid wheat increased the shape and weight of wheat grains in a dosage-dependent manner suggesting an important role of TaGW7 for deciding yield component during domestication of wheat (Wang, Pan, et al, 2019). Considering the vast application of the CRISPR/Cas9 system and speeding the traits improvement in wheat, researchers have devised a web-based tool, WheatCRISPR, for designing precise sgRNAs.…”

“…Advancements in next generation sequencing and data processing techniques have improved the understanding of genetic diversity, making it feasible to look beyond the knowledge generated from a model species and explore the evolution of signalling pathways in the specific ecological context of crop breeding programs. Studies have applied comparative genomic approaches to select agronomic traits such as grain yield and quality for rice [ 98 , 99 ], photoperiod sensitivity in maize [ 100 ] and grain size and shape in wheat [ 101 ]. Despite the wide application of genome sequencing and pan-genome analysis for improving cereal traits, the diversity and role of KAR and SL pathways remain unexplored with regard to their role in shade avoidance, the regulation of germination, seed vigour and plant development across cereal species such as wheat, maize, rice and barley.…”
