Access   Prochlorophytes similar toProchloron sp.
andProchlorothrix hollandica have been suggested as possible
progenitors of the plastids of green algae and land plants
because they are prokaryotic organisms that possess chlorophyllb
(chlb). We have sequenced theProchlorothrix genes encoding the
large and small subunits of ribulose-1,5-bisphosphate
carboxylase/oxygenase (rubisco),rbcL andrbcS, for comparison
with those of other taxa to assess the phylogenetic relationship
of this species. Length differences in the large subunit
polypeptide among all sequences compared occur primarily at the
amino terminus,
