Rathayibacter tanaceti sp. nov., a Novel Actinobacterium from Tanacetum vulgare Infested by Foliar Nematode Aphelenchoides sp
Two novel yellow-pigmented, rod-shaped and non-motile coryneform actinobacteria, strains VKM Ac-2596 T and VKM Ac-2761, were isolated from a plant Tanacetum vulgare (Asteraceae) infested by foliar nematode Aphelenchoides sp. The strains exhibited the highest 16S rRNA gene sequence similarities to Ra...

Summary: | Two novel yellow-pigmented, rod-shaped and non-motile coryneform actinobacteria, strains VKM Ac-2596
T
and VKM Ac-2761, were isolated from a plant
Tanacetum vulgare
(Asteraceae) infested by foliar nematode
Aphelenchoides
sp. The strains exhibited the highest 16S rRNA gene sequence similarities to
Rathayibacter agropyri
CA4
T
(99.71%),
Rathayibacter rathayi
DSM 7485
T
(99.65%) and
Rathayibacter iranicus
VKM Ac-1602
T
(99.65%). The pairwise average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between VKM Ac-2596
T
and VKM Ac-2671 towards the type strains of
Rathayibacter
species did not exceed 85.24% and 29.40%, respectively, that are well below the thresholds for species delineation. The target strains had key chemotaxonomic properties typical of the genus
Rathayibacter
, namely, the DAB-based peptidoglycan, rhamnose and mannose as the predominant sugars and a rhamnomannan in the cell, the major menaquinone MK-10 and fatty acids of iso-anteiso type, with a large proportion of anteiso-15:0. The strains showed clear differences from the recognized
Rathayibacter
species in several phenotypic characteristics, including the difference in the composition of cell wall glycopolymers. Based on the results obtained in this study and the data published previously, we provide a description of a new species,
Rathayibacter tanaceti
sp. nov., with DL-642
T
(= VKM Ac-2596
T
= LMG 33114
T
) as the type strain. |
