Abstract: A bacterial strain designated as RZME10T was isolated from a Zea mays L. root collected in Spain. Results of analysis of the 16S rRNA gene sequence showed that this strain belongs to the genus Agrobacterium with Agrobacterium larrymoorei ATCC 51759T being the most closely related species with 99.9 % sequence similarity. The similarity values of the rpoB, recA, gyrB, atpD and glnII genes between strain RZME10T and A. larrymoorei ATCC 51759T 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 RZME10T are those from summed feature 8 (C18 : 1 ω6c/C18 : 1 ω7c) and C16 : 0. Pathogenicity tests on tomato and carrot roots showed that strain RZME10T was not able to induce plant tumours. Based on the results of genomic, chemotaxonomic and phenotypic analyses, we propose that strain RZME10T represents a novel species named Agrobacterium cavarae sp. nov. (type strain RZME10T=CECT 9795T=LMG 31257T).
