Amino acid replacement sites in 18 Potamogeton species and Stuckenia RbcL.

Number corresponds to the amino acid position of spinach RbcL. (?): homophyllous plant with submerged leaves, (+): heterophyllous plant with submerged and floating leaves, (++): heterophyllous plant with submerged, floating and terrestrial leaves.athe species is also distributed in brackish water.b*: residues that are close to the active sites, c: residues that are buried in the interior of RbcL, D: residues at the intradimer interface of RbcL, i: residues at the interface between RbcL and RbcS.cprobabilities above 0.95 are indicated in bold.
