metadata.name: dc.description.abstract
metadata.value: Rhizosphere bacteria are capable of utilizing various phytohormones (particularly
  auxins) as nutrients and thereby affect plant growth, nutrition and interactions
  with symbiotic microorganisms. Here, for the first time we evaluated the
  effects of rhizosphere bacteria Novosphingobium sp. P6W and Rhodococcus sp.
  P1Y capable of utilizing abscisic acid (ABA) on growth and nitrogen-fixing symbiosis
  of pea (Pisum sativum L.) line SGE and its Cd-insensitive mutant SGECdt
  using hydroponic culture. The plants were co-inoculated with the ABA-utilizing
  bacteria and nodule bacterium Rhizobium leguminosarum bv. viciae RCAM1066.
  Treatment with cadmium (Cd) was applied as an inducer of ABA biosynthesis
  in plants. In the presence of only nodule bacteria, Cd significantly inhibited
  the growth of roots and shoots and also decreased the nodule number and
  nitrogen-fixing activity in SGE peas, but not in the SGECdt mutant. Inoculation
  with ABA-utilizing bacteria also inhibited biomass production, nodulation and
  nitrogen-fixation of Cd-untreated SGE plants. This negative effect of bacteria on
  the SGECdt mutant was less pronounced. Contrary to this, ABA-utilizing bacteria
  had no effect on SGE plants treated with Cd, but decreased shoot biomass
  and nitrogen-fixing activity of the SGECdt mutant. Inoculation with ABA-utilizing
  bacteria had no effect on shoot Cd and nutrient content of both pea genotypes,
  suggesting that bacterial effects on plants were not associated with the plant
  nutrient status. We propose that the bacteria counteracted the increased ABA
  concentrations in SGE roots caused by Cd due to utilization of this phytohormone.
  However, opposite processes aimed at inhibiting and stimulating growth
  and legume–rhizobia symbiosis can be caused by the ABA-utilizing bacteria.
