Phototrophy has not been found in Deltaproteobacteria. Using bioinformatics, I show that two distant strains of Deltaproteobacteria probably acquired phototrophy via a single event of horizontal gene transfer from Alphaproteobacteria into the most recent common ancestor of the proposed class of Deltaproteobacteria, Polyangia.
I have uploaded a short document to Researchgate with the details of this. Please have a look if you're interested and leave some feedback.

Great, my congratulations!
ReplyDeleteSo, I hope that now you will be more optimistic about possibility of acquisition the photosynthesis machinery through HGT events. ))
