Figure 2.

Alignment of deduced amino acid sequences of sdhB genes from rice (this study), human (24, 25), malarial parasite (P. falciparum; DDBJ accession no. D86574), and nuclear rps14 from rice (this study). Amino acid residues identical to the rice SDHB are highlighted by reverse contrast. The three thick bars above the sequence represent three cysteine-rich clusters, which are highly conserved among sdhB genes. An RPS14-homologous region in the rice rps14 gene is indicated by a bent arrow. Arrowheads indicate the intron position of rice sdhB and rps14 genes.
