TL;DR: Genomic signatures of selection and domestication are associated with positively selected genes (PSGs) for fiber improvement in the A subgenome and for stress tolerance in the D subgenomes, suggesting asymmetric evolution.

TL;DR: The roles of the two GmNAC genes in stress tolerance were further analyzed in soybean transgenic hairy roots and provide a basis for genetic manipulation to improve the agronomic traits of important crops.

TL;DR: This study identified large numbers of miRNAs and their related target genes through deep sequencing of a small RNA library and a degradome library and advances the understanding of miRNA functions during seed development.

TL;DR: Sequencing and genomic diversification of five allopolyploid cotton species provide insights into polyploid genome evolution and epigenetic landscapes for cotton improvement, and will empower efforts to manipulate genetic recombination and modify epigenetics landscapes and target genes for crop improvement.

TL;DR: Development regulation and epigenetic changes including DNA methylation and histone modifications in polyploids are reviewed, which suggest that epigenetic modifications can alter homoeologous gene expression and reprogram gene expression networks, which allows polyploidy to establish new cytotypes, grow vigorously and promote adaptation in local environments.
