Meiotic homoeologous recombination-based mapping of wheat chromosome 2B and its homoeologues in Aegilops speltoides and Thinopyrum elongatum

Key message We physically dissected and mapped wheat chromosome 2B and its homoeologues in Aegilops speltoides and Thinopyrum elongatum based on meiotic homoeologous recombination, providing a unique physical framework for genome studies.
