Phytohabitans suffuscus gen. nov., sp. nov., an actinomycete of the family Micromonosporaceae isolated from plant roots

<jats:p>An actinomycete strain, K07-0523<jats:sup>T</jats:sup>, was isolated from the roots of an orchid collected in Okinawa prefecture, Japan. 16S rRNA gene sequence analysis indicated that the new strain belonged to the family <jats:italic>Micromonosporaceae</jats:italic> and the similarity values between strain K07-0523<jats:sup>T</jats:sup> and the type species of 24 genera in the family <jats:italic>Micromonosporaceae</jats:italic> were 93.3–97.7 %. Strain K07-0523<jats:sup>T</jats:sup> contained <jats:sc>d</jats:sc>-glutamic acid, glycine, <jats:sc>d</jats:sc>-alanine, <jats:italic>meso</jats:italic>-diaminopimelic acid, hydroxydiaminopimelic acid and <jats:sc>l</jats:sc>-lysine in the cell wall. The major menaquinones were MK-9(H<jats:sub>6</jats:sub>), MK-10(H<jats:sub>4</jats:sub>) and MK-10(H<jats:sub>6</jats:sub>). Galactose, glucose, mannose, ribose and xylose were present in the whole-cell sugars. The acyl type of the peptidoglycan was glycolyl. Major fatty acids were anteiso-C<jats:sub>17 : 0</jats:sub>, iso-C<jats:sub>17 : 0</jats:sub>, iso-C<jats:sub>16 : 0</jats:sub> and iso-C<jats:sub>15 : 0</jats:sub>. Phosphatidylethanolamine was detected as the major phospholipid and corresponded to phospholipid type II. The G+C content of the genomic DNA was 73 mol%. On the basis of phylogenetic and chemotaxonomic data, the new strain represents a member of a new genus and novel species, namely <jats:italic>Phytohabitans suffuscus</jats:italic> gen. nov., sp. nov., in the family <jats:italic>Micromonosporaceae</jats:italic>. The type strain of the type species is K07-0523<jats:sup>T</jats:sup> (=DSM 45306<jats:sup>T</jats:sup>=NBRC 105367<jats:sup>T</jats:sup>).</jats:p>
