Figure 5 From: The complete chloroplast DNA sequences of the charophycean green algae Staurastrum and Zygnema reveal that the chloroplast genome underwent extensive changes during the evolution of the Zygnematales Sequence conservation among streptophyte MatK proteins. The MatK sequences of selected green algae and land plants were aligned with T-COFFEE [40] and arranged into two separate groups. Identical amino acids in all the sequences examined are displayed on a black background, whereas identical amino acids in all the green algal or land plant sequences are shown on a dark grey background. In each group, sets of residues sharing eight of the 10 features in the property matrix of AMAS [41] are shown on a light grey background. The accession numbers for the MatK sequences analyzed are as follows: Zygnema, [GenBank:AY958086]; Staurastrum, [GenBank:AY958085]; Chaetosphaeridium, [GenBank:NC_004115]; Chara connivens, [GenBank:AY170442]; Nitella opaca, [GenBank:AY170449]; Marchantia, [GenBank:NC_001319]; and Physcomitrella patens [GenBank:NC_005087].Back to article page
