Contribution of plant–bacteria interactions to horizontal gene transfer in plants

Horizontal gene transfer (HGT) is recognized as a major driver of adaptive evolution in prokaryotes. However, HGT seems impossible in eukaryotes, particularly as recipients; therefore, debate rages regarding whether HGT takes place in eukaryotes, in addition to its potential mechanism or frequency....
