Representatives of this clade are known to be metabolically versatile and involved in marine carbon-producing and biogeo-chemical processes. They form a physiologically heterogeneous group of Alphaproteobacteria and were mostly found in coastal or polar waters, especially in symbio-sis with algae, in microbial mats, in sediments or together with invertebrates and vertebrates. Here we describe the features of L. arenae DSM 19593 T , including novel aspects of its pheno-type, together with the draft genome sequence and annotation. The 3,690,113 bp long ge-nome consists of 17 scaffolds with 3,601 protein-coding and 56 RNA genes. This genome was sequenced as part of the activities of the Transregional Collaborative Research Centre 51 funded by the German Research Foundation (DFG). Introduction Strain GA2-M15 T (= DSM 19593 = KACC 12675) is the type strain of the species Litoreibacter arena [1,2]. The genus Litoreibacter is a member of the highly abundant marine Roseobacter lineage, which plays an important role in the global carb and sulfur cycles, and us for the climate on Earth. Phylogenetically, this alphaproteobacterial genus is related to the genera Jannaschia, Octadecabacter and Thalassobius [1]. Strain GA2-M15 T was isolated from a sea-sand sample from the coast of Homi Cape, Pohang City, South Korea as Thalassobacter arenae [1], which was later on reclassified into Litoreibacter arenae [2]. The name for the genus Litoreibacter was constructed from litoreus (‘belonging to the seashore’) and bacter (‘a rod’) [3]. The species epithet arenae re-fers to the Neolatin adjective arenae, ‘of sand’. Current PubMed records do not indicate any fol-low-up research with strain GA2-M15 T after the initial description of T. arenae [1] and its reclassi-fication into L. arenae [2]. Here we present a summary classification and a set of features for L. arenae DSM 19593 T , including novel aspects of its phenotype, together with the description of the genomic sequencing and annotation.
