Cotton is an irreplaceable economic crop currently domesticated in the human world for its
extremely elongated fiber cells specialized in seed epidermis, which makes it of high …

Many newly created early maturing varieties exhibit poor stress resistance and low yield,
whereas stress-resistant varieties are typically late maturing. For this reason, the …

Phenotypic diversity and evolutionary innovation ultimately trace to variation in genomic
sequence and rewiring of regulatory networks. Here, we constructed a pan-genome of the …

Large-scale genomic surveys of crop germplasm are important for understanding the
genetic architecture of favorable traits. The genomic basis of geographic differentiation and …

Background Millennia of directional human selection has reshaped the genomic architecture
of cultivated cotton relative to wild counterparts, but we have limited understanding of the …

Polyploidy complicates transcriptional regulation and increases phenotypic diversity in
organisms. The dynamics of genetic regulation of gene expression between coresident …

Background Homoeologs are defined as homologous genes resulting from allopolyploidy.
Bread wheat, Triticum aestivum, is an allohexaploid species with many homoeologs …

Allotetraploid cotton (Gossypium) species represents a model system for the study of plant
polyploidy, molecular evolution, and domestication. Here, chromosome-scale genome …

Structural variations (SVs) have long been described as being involved in the origin,
adaption, and domestication of species. However, the underlying genetic and genomic …

Allopolyploidization, resulting in divergent genomes in the same cell, is believed to trigger a
“genome shock”, leading to broad genetic and epigenetic changes. However, little is …
