Abstract
The first complete mitochondrial genome (27,943 bp) of the halymenialean red alga, Grateloupia angusta, was sequenced. The circular mitogenome contains 47 genes, including 26 protein-coding, 19 tRNA and 2 rRNA genes. The rps3 and rpl16 genes are overlapped by 7 bp. The majority of protein-coding genes (17 of 26 genes) use typical ATG start codon, however, 9 genes use alternative start codons such as ATT, AAT, TTA and TTG. The G. angusta mitogenome shows a significant difference to that of Chondrus crispus (Gigartinales) in gene synteny and tRNA compositions.
