Coexpression comparison to investigate the functional orthologs, using the sequence orthologs. There are two rice orthologs for the Arabidopsis NPQ4 gene. Although both genes show similar coexpression to Arabidopsis NPQ4, Os01g0869800 shows stronger coexpression than Os04g0690800, suggesting that Os01g0869800 is the functional ortholog of Arabidopsis NPQ4.
