Interspecific hybridization of lady’s slipper orchids (Paphiopedilum) has long been used for breeding programs; however, genome affinities among species are almost unknown. Lee et al. investigate meiotic chromosome paring in eight hybrids and propose that genome homology and the interaction of genetic factors, but not chromosome number or karyotype similarity, determine the chromosome paring affinities in these hybrids.
When two different genomes come together in a hybrid or polyploid, it can trigger conflict in the new genome. A review in New Phytologist investigates how one subgenome can become dominant.
This study uses flow sorting and FISH techniques to further the development of molecular tools to progress introgression breeding in wheat
Most cooking and several desert bananas are interspecific triploid hybrids between Musa acuminata (A genome) and M. balbisiana (B genome). To investigate the possibility of chromosome exchanges between these two...
