Abstract

Abstract: Gracilaria salicornia is an agarophyte that has been used as food and as a source of agar. We sequenced the complete mitogenome of the species from Malaysia and compared it with the previously described sequence from Hawaii. It had a total length of 25, 915 bp, comprising 50 genes [25 protein-coding genes (PCGs), 2 rRNA genes and 23 tRNA genes]. It was larger than the Hawaiian sequence (25, 272 bp) and possessed three additional tRNAs ( trnY, trnR, trnS1 ). Both G. salicornia sequences had the same start and stop codons for all the PCGs. The genetic distance between the peninsular Malaysian and Hawaiian samples was 0.44% based on 19 PCGs, 0.15% based on 2 rRNA genes and 0.38% based on 19 PCGs + 2 rRNA genes. The phylogram of G. salicornia within Gracilariaceae based on 19 PCGs was congruent with that based on 19 PCGs + 2 rRNA genes.
