What'sNEW
Horizontal gene transfer (HGT) has profoundly shaped eukaryotic organellar genomes like plant mitochondria. This phenomenon gets close inspection by a pair of geneticists at the University of Florida, using a newly developed analytical tool. Their writeup concentrates on the tool and its uses; they hope it will bring helpful new information to plant taxonomy, beyond what can be learned by more traditional methods.
They say that blocks of genetic programming, from ~50 to ~1,500 bp originated somewhere else, when what they observe is only that the blocks appear to have been first deployed somewhere else. And the complicated insertions, deletions and rearrangements following HGT (illustrated) are carefully diagrammed without much curiosity about how this happens. My summary observation is that the long reach of HGT continues to find excess corroboration — and the implications for evolution continue to go unnoticed.
