sp. nov., isolated from maize ( L.) roots.

A bacterial strain designated as RZME10 was isolated from a L. root collected in Spain. Results of analysis of the 16S rRNA gene sequence showed that this strain belongs to the genus with ATCC 51759 being the most closely related species with 99.9 % sequence similarity. The similarity values of the , , , and genes between strain RZME10 and ATCC 51759 were 93.5, 90.0, 88.7, 87.9 and 90.1 %, respectively. The estimated average nucleotide identity using blast and digital DNA-DNA hybridization values between these two strains were 80.4 and 30.2 %, respectively. The major fatty acids of strain RZME10 are those from summed feature 8 (C ω6/C ω7) and C. Pathogenicity tests on tomato and carrot roots showed that strain RZME10 was not able to induce plant tumours. Based on the results of genomic, chemotaxonomic and phenotypic analyses, we propose that strain RZME10 represents a novel species named sp. nov. (type strain RZME10=CECT 9795=LMG 31257).
