Agreia bicolorata gen. nov., sp nov., to accommodate actinobacteria isolated from narrow reed grass infected by the nematode Heteroanguina graminophila

Agreia bicolorata gen. nov., sp. nov. (type strain VKM Ac-1804(T) = UCM Ac- 620(T)) is proposed to accommodate aerobic, oxidase- and catalase-positive, weakly motile, coryneform actinobacteria isolated from leaf galls induced by the plant-parasitic nematode Heteroanguina graminophila in narrow reed g rass, Calamagrostis neglecta. Bacteria assigned to Agreia bicolorata gen. n ov., sp. nov. form a distinct lineage within the phylogenetic branch of the family Microbacteriaceae and possess the following chemotaxonomic characte ristics: B-type peptidoglycan containing 2,4-diaminobutyric acid, ornithine , alanine, glycine, glutamate and hydroxyglutamate; cell wall sugars rhamno se, fucose and mannose; MK-10 as major menaquinone; phosphatidylglycerol an d diphosphatidylglycerol as principal phospholipids; and 12-methyltetradeca noic acid (anteiso-15:0), 14-methyl-pentadecanoic acid (iso-16:0) and 14-me thyl-hexadecanoic acid (anteiso-17:0) as predominant fatty acids. The DNA G +C content of Agreia bicolorata is about 67.0 mol %.
