  abstract = {t{T}he taxonomic status of eleven rhizospheric bacterial strains belonging to the genus {B}urkholderia andisolated from roots of {C}ostularia ({C}yperaceae), tropical herbaceous pioneer plants growing on ultramaficsoils in {N}ew {C}aledonia, was investigated using a polyphasic taxonomic approach. {T}he genetic analyses(16{S} r{RNA} genes, gyr{B}, rec{A}, nre{B} and cnr) confirmed that all strains are {B}urkholderia and cluster into twoseparated groups. {T}he {DNA} hybridization results showed low relatedness values to the closest relatives{B}urkholderia species. {T}he phenotypic analyses confirmed that the two groups of strains could be differ-entiated from each other and from other known {B}urkholderia species. {T}his polyphasic study revealedthat these two groups of strains represent each a novel species of {B}urkholderia, for which the names{B}urkholderia novacaledonica sp. nov. (type strain {STM}10272{T}= {LMG}28615{T}= {CIP}110887{T}) and {B}. ultra-mafica sp. nov. (type strain {STM}10279{T}= {LMG}28614{T}= {CIP}110886{T}) are proposed, respectively. {T}hesestrains of {B}urkholderia presented specific ecological traits such as the tolerance to the extreme edaphicconstraints of ultramafic soils: they grew at p{H} between 4 and 8 and tolerate the strong unbalanced{C}a/{M}g ratio (1/19) and the high concentrations of heavy metals i.e. {C}o, {C}r, {M}n and {N}i. {N}oteworthy {B}.ultramafica tolerated nickel until 10 m{M} and {B}. novacaledonica up to 5 m{M}. {T}he presence of the nickel(nre{B}) and cobalt/nickel (cnr) resistance determinants encoding for protein involved in metal tolerancewas found in all strains of both groups. {M}oreover, most of the strains were able to produce plant growthpromoting molecules ({ACC}, {IAA}, {NH}3and siderophores). {S}uch ecological traits suggest that these newspecies of {B}urkholderia might be environmentally adaptable plant-associated bacteria and beneficialto plants.},
