Abstract Polyploidy or whole-genome duplication (WGD) is widespread in plants and a key driver of evolution speciation, accompanied by rapid dynamic changes genomic structure gene expression. The 3D the genome intricately linked to expression, but its role transcription regulation following polyploidy domestication remains unclear. Here, we generated high-resolution (∼2 kb) Hi-C maps for cultivated soybean (Glycine max), wild soja), common bean (Phaseolus vulgaris). We found polyploidization...
Bread wheat (Triticum aestivum) is an allohexaploid that generated by two subsequent allopolyploidization events. The large genome size (16 Gb) and polyploid complexity impede our understanding of how regulatory elements their interactions shape chromatin structure gene expression in wheat. open enrichment network Hi-C (OCEAN-C) a powerful antibody-independent method to detect between regions throughout the genome.
Soybean (Glycine max L. Merrill) is one of the most important commercial crops worldwide. However, soybean has undergone severe genetic bottlenecks during domestication (Hyten et al., 2006). It essential to exploit novel sources diversity and expand gene pools for improvement. Plant mutation breeding been widely used by plant breeders create diversity. Ethyl methanesulfonate (EMS) a chemical mutagen believed mainly induce point mutations, which commonly develop mutant populations in (Li...
Bread wheat (Triticum aestivum) is an allohexaploid that was formed via two allopolyploidization events. Growing evidence suggests histone modifications are involved in the response to 'genomic shock' and environmental adaptation during polyploid formation evolution. However, role of modifications, especially H3 lysine-27 dimethylation (H3K27me2), genome evolution remains elusive. Here we analyzed H3K27me2 H3K27me3 profiles hexaploid its tetraploid diploid relatives. Although levels were...
