I had a look at my dataset of D1 sequences from Cyanobacteria. You may find interesting that Ala87 is not unique to plants and actually is a trait of early-evolving atypical D1 sequences (rogue and super-rogue) and also of standard D1 forms of early evolving cyanobacteria, like the marine yellowstone Synechococcus (Ja-3-3Ab) or Synechococcus sp. PCC 7336. It is kind of cool because in my 2015 Mol Biol Evol paper, the plant D1 clustered with this early evolving cyanos.
