Figure 2.

GP1 shaft sequences from C. reinhardtii and C. incerta showing nucleotide-based alignment. Ser residues are shaded dark gray for UCX codons and light gray for AGX codons. Non-Ser amino acids are shaded light gray when they share two nucleotides with the aligned Ser codon. Conserved nucleotide positions are marked with asterisks. Two predicted endoduplications are highlighted in black, with nucleotide identities shown above duplicates. Tajima-Nei distance: 0.203 ± 0.018. Sequence numbering on the alignments starts at nucleotide no. 118 of both subdomains; complete coding sequences are deposited at GenBank.
