Homoeologous exchanges, segmental allopolyploidy, and polyploid genome evolution
Polyploidy is a major force in plant evolution and speciation. In newly formed allopolyploids,
pairing between related chromosomes from different subgenomes (homoeologous …

Myb10‐D confers PHS‐3D resistance to pre‐harvest sprouting by regulating NCED in ABA biosynthesis pathway of wheat
Summary Pre‐harvest sprouting (PHS), the germination of grain before harvest, is a serious
problem resulting in wheat yield and quality losses. Here, we mapped the PHS resistance …
