Complete mitogenome of the chlorophyte green alga Marsupiomonas sp. NIES 1824 (Pedinophyceae)

The 25,137-bp mitogenome of the green alga Pedinomonas minor (Pedinomonadales, Pedinophyceae), which belongs to a basal class of the core Chlorophyta, is unusual in displaying a reduced gene content as well as other derived traits. Here, we present the mitogenome of Marsupiomonas sp. NIES 1824 (Mars...

Sumario:The 25,137-bp mitogenome of the green alga Pedinomonas minor (Pedinomonadales, Pedinophyceae), which belongs to a basal class of the core Chlorophyta, is unusual in displaying a reduced gene content as well as other derived traits. Here, we present the mitogenome of Marsupiomonas sp. NIES 1824 (Marsupiomonadales, Pedinophyceae). Despite its smaller size, this 24,252-bp genome encodes twice as many genes (39) as its P. minor homolog. Besides gradual gene erosion, our comparative analyses revealed that major changes in GC content and codon usage led to the gain of distinct, noncanonical genetic codes during evolution of the mitogenome in the Pedinophyceae.
