Polyphyletic origin of land plants: Bryophytes are fungi with chloroplasts.
BRYOPHYTES are generally considered to be derived from some algae and ancestors of ferns leading to higher plants.Our molecular studies of a slow evolving nuclear gene, histone 3, clearly show that protein sequences of histone 3 in various bryophytes including liverworts, mosses, and hornworts are similar to those of fungi, but different from those of other land plants. This result shows that there are two diferent possibilities; One is that bryophytes are derived from fungi by independent symbiosis with chloroplasts, the other is horizontal transfer of histone 3 genes before divergence of bryophytes to different classes. We will discuss possible hypotheses about this extraordinary events.
