Abstract:The genes were cloned for the two apoprotein subunits, agr and beta,of phycocyanin from the cyanobacterium Spirulina maxima = Arthrospiramaxima) strain F3. The agr- and beta-subunit gene-coding regionscontain 489 bp and 519 bp, respectively. The beta-subunit gene is upstreamfrom the agr-subunit gene, with a 111-bp segment separating them.Similarities between the agr-subunits of S. maxima and nine othercyanobacteria were between 58% and 99%, as were those between the beta-subunits. The maximum similarity between the agr- and beta-subunits from S. maxima was 27%.
Keywords:phycocyanin gene  Spirulina maxima  Arthrospira  evolutionary analysis
