Crossovers Get a Boost in Brassica Allotriploid and Allotetraploid Hybrids[W]

摘要

There is a great demand to increase meiotic crossovers frequency in order to boost genetic diversity in traditional breeding and genetic studies. This work shows that this can be achieved by manipulating karyotype composition (diploid vs. allotriploid vs. allotetraploid) of plant hybrids.
