PG - 126090 LID - S0723-2020(20)30041-2 [pii] LID - 10.1016/j.syapm.2020.126090 [doi] AB - Four strains, coded as UPM1132, UPM1133(T), UPM1134 and UPM1135, and isolated from nodules of Pisum sativum plants grown on Ni-rich soils were characterised through a polyphasic taxonomy approach. Their 16S rRNA gene sequences were identical and showed 100% similarity with their closest phylogenetic neighbors, the species included in the 'R. leguminosarum group': R. laguerreae FB206(T), R. leguminosarum USDA 2370(T), R. anhuiense CCBAU 23252(T), R. sophoreae CCBAU 03386(T), R. acidisoli FH13(T) and R. hidalgonense FH14(T), and 99.6% sequence similarity with R. esperanzae CNPSo 668(T). The analysis of combined housekeeping genes recA, atpD and glnII sequences showed similarities of 92-95% with the closest relatives. Whole genome average nucleotide identity (ANI) values were 97.5-99.7% ANIb similarity among the four strains, and less than 92.4% with closely related species, while digital DNA-DNA hybridization average values (dDDH) were 82-85% within our strains and 34-52% with closely related species. Major fatty acids in strain UPM1133(T) were C18:1 omega7c / C18:1 omega6c in summed feature 8, C14:0 3OH/ C16:1 iso I in summed feature 2 and C18:0. Colonies were small to medium, pearl-white coloured in YMA at 28 degrees C and growth was observed in the ranges 8-34 degrees C, pH 5.5-7.5 and 0-0.7% (w/v) NaCl. The DNA G+C content was 60.8mol %. The combined genotypic, phenotypic and chemotaxonomic data support the classification of strains UPM1132, UPM1133(T), UPM1134 and UPM1135 into a novel species of Rhizobium, for which the name Rhizobium ruizarguesonis sp. nov. is proposed. The type strain is UPM1133(T) (=CECT 9542(T)=LMG 30526(T)). CI - Copyright (c) 2020 Elsevier GmbH. All rights reserved.
