Fig. 1.

Structural comparison of CGHR family members in the P. tricornutum genome and conserved regions in CGHR family proteins from other photoautotrophs. (A) Schematic drawing of P. tricornutum CGHR family genes on chromosome 1. Magenta arrows indicate the cDNA sequence regions for CGHR family genes, and the numbers above the arrows represent their corresponding lengths. The numbers shown below the arrows indicate the length of noncoding regions. (B) Comparison of the conserved regions in CGHR family proteins from bacteria, cyanobacteria, and eukaryotic algae. (C) Schematic drawings of notable domain structures of four P. tricornutum CGHR family members.
