Phylogenetic tree of all Lhc-like proteins identified in A. thaliana (At), Populus trichocarpa (Pt), O. sativa (Os), P. patens (Pp), C. reinhardtii (Cr) and O. tauri (Ot). Sequences obtained from several algae species EST databases were also included (Acetabularia acetabulum, Aa, Mesostigma viride, Mv, Micromonas sp., Msp, Bigelowiella natans, Bn). In Figure A only proteins with at least two homologous transmembrane helices are shown. In figure B all transmembrane helices were analyzed individually and roman numerals indicating the helix number. In both analyses some Lhca and Lhcb sequences were included as an external out-group. The tree shown was obtained with a maximum likelihood approach, but bootstrap values were obtained from maximum likelihood, NJD and maximum parsimony respectively. For clarity, bootstrap values are not shown when consistency was poor and when nodes are not useful to discriminate isoforms.
