Tolerance of lespedeza Bradyrhizobium to acidity, aluminum, and manganese in culture media containing glutamate or ammonium

Plant symbiotic microorganisms in acid sulfate soil: significance in the growth of pioneer plants

“…The acid-tolerant bradyrhizobia associated with Lespedeza spp. were able to grow on acidic agar media, but the lower limit of the in vitro growth of these strains was pH 4.5 (Cline and Senwo 1994), reflecting the acid-tolerance of the host plant that could not grow below pH 4.5 (Cline and Senwo 1993). Our observation that L. cyrtobotrya occurred in soils with pH more than 4.5 is in good agreement with that of Cline and Senwo (1993).…”

“…In acidic soil, however, it seems likely that Bradyrhizobium spp. are the major symbiotic partners (Cline and Senwo 1994). The acid-tolerant bradyrhizobia associated with Lespedeza spp.…”

Características fisiológicas e ecológicas de isolados de rizóbios oriundos de solos ácidos e álicos de Presidente Figueiredo, Amazonas

“…Geralmente, os isolados obtidos de solos mais ácidos são mais tolerantes à acidez (Cline & Senwo, 1994). Ramos et al (1987) observaram que apenas 17% dos isolados de solos que sofreram calagem apresentaram tolerância à acidez.…”

Factors Influencing Nodule Occupancy by Inoculant Rhizobia

“…Screening for rhizobial resistance to high A13+ or Mn2+ concentrations among cowpea bradyrhizobia (Keyser and Munns, 1979a,b;Ayanaba et al, 1983), lespedeza bradyrhizobia (Cline and Senwo, 1994), B. japonicum (Ayanaba et al, 1983), R. loti (Cooper, 1982;Wood and Cooper, 1985), R. leguminosarurn bv. trifolii (Thornton and Davey, 1983;Wood and Cooper, 1984;Richardson and Simpson, 1989), and bean rhizobia (Graham et al, 1982;Lowendorf and Alexander, 1983a;Karanja and Wood, 1988a;Vargas and Graham, 1988;Wolff et al, 1991) has shown that a tremendous difference exists in aluminum and manganese tolerance within and between species and that tolerance to acidity does not necessarily imply tolerance to these elements.…”
