Abstract:
:To get deeper insight into the evolution of phosphoenolpyruvate carboxylase we have identified PEPC fragments (about 1,100 bp) of another 12 plants species not yet investigated in this context. The selected plants include one Chlorophyta, two Bryophyta, four Pteridophyta, and five Spermatophyta species. The obtained phylogenetic trees on PEPC isoforms are the most complete ones up to now available. Independent of their manner of construction, the resulting dendrograms are very similar and fully consistent with the main topology as it is postulated for the evolution of the higher terrestrial plants. We found a distinct clustering of the PEPC sequences of the prokaryotes, the algae, and the spermatophytes. PEPC isoforms of the archegoniates are located in the phylogenetic trees between the algae and spermatophytes. Our results strengthen the view that the PEPC is a very useful molecular marker with which to visualize phylogenetic trends both on the metabolic and organismic levels.
