Novel microsatellite markers suggest significant genetic isolation in the Eastern Pacific sponge Aplysina gerardogreeni.

Background: The Eastern Tropical Pacific (ETP) harbors a great diversity of Porifera. In particular, the Aplysina genus has acquired biotechnological and pharmacological importance. Nevertheless, the ecological aspects of their species and populations have been poorly studied.

Complete mitochondrial genome of the beaubrummel Damselfish, Stegastes flavilatus (Pisces: Perciformes, Pomacentridae).

The mitogenome of the beaubrummel damselfish, Stegastes flavilatus Gill, 1862 (Genebank accession number KP136922), has a total length of 16,816 bp. It encodes 13 protein-coding, two ribosomal RNAs (rRNAs), and 22 transfer RNA (tRNA) genes. Base composition is 28.

The complete mitochondrial DNA of the Pacific Geoduck clam (Panopea generosa).

The complete mitochondrial genome of the Pacific Geoduck Panopea generosa (Genbank accession KM580067) is 15,585 bp in size and contains the typical 37 genes (13 protein-coding, 2 ribosomal RNA and 22 transfer RNA) found in metazoan mitogenomes, including the rare ATPase subunit 8 gene (ATP8). All genes are coded in the same strand but the gene arrangement is novel among heterodont bivalves. The base composition was: A 25.

Novel gene arrangement in the mitochondrial genome of the Cortés Geoduck clam (Panopea globosa).

The mitogenome of the Cortés geoduck clam Panopea globosa (Genbank accession KM580068) has a length of 15,469 bp and contains 13 protein-coding genes, 2 ribosomal RNA and 22 transfer RNA genes, as conventional metazoan mitochondrial genomes. Structural genes start with ATG, ATA and GTG codons; whereas TAG and TAA are used as stop codons. Base composition is: 23.
