Résumé : Class III peroxidases are members of a large multigenic family, only detected in the plant kingdom and absent from green algae sensu stricto (chlorophyte algae or Chlorophyta). Their evolution is thought to be related to the emergence of the land plants. However class III peroxidases are present in a lower copy number in some basal Streptophytes (Charapyceae), which predate land colonization. Gene structures are variable among organisms and within species with respect to the number of introns, but their positions are highly conserved. Their high copy number, as well as their conservation could be related to plant complexity and adaptation to increasing stresses. No specific function has been assigned to respective isoforms, but in large multigenic families, particular structure–function relations can be expected. Plant peroxidase sequences contain highly conserved residues and motifs, variable domains surrounded by conserved residues and present a low identity level among their promoter regions, further suggesting the existence of sub-functionalization of the different isoforms.
