The ability of Burkholderia phymatum STM815 to effectively nodulate Mimosa spp., and to fix nitrogen ex planta, was compared with that of the known Mimosa symbiont Cupriavidus taiwanensis LMG19424. Both strains were equally effective symbionts of M. pudica, but nodules formed by STM815 had greater nitrogenase activity. STM815 was shown to have a broader host range across the genus Mimosa than LMG19424, nodulating 30 out of 31 species, 21 of these effectively. LMG19424 effectively nodulated only nine species. GFP-marked variants were used to visualise symbiont presence within nodules. STM815 gave significant acetylene reduction assay (ARA) activity in semisolid JMV medium ex planta, but no ARA activity was detected with LMG19424. 16S rDNA sequences of two isolates originally from Mimosa nodules in Papua New Guinea (NGR114 and NGR195A) identified them as Burkholderia phymatum also, with nodA, nodC and nifH genes of NGR195A identical to those of STM815. B. phymatum is therefore an effective Mimosa symbiont with a broad host range, and is the first reported beta-rhizobial strain to fix nitrogen in free-living culture. |

Aplications of Zinc (Zn) and copper (Cu) at excessive rates may result in phytotoxicity. Experiments were conducted with mixtures of soils that were similar except for their and Cu levels. The critical toxicity levels (CTL) in the soil and plants for these elements were determined. Peanut (Arachis hypogaea L.), soybean (Glycine max (L.) Merr.), corn (Zea mays L.), and rice (oryza sativa L.) were the crops grown. One soil mixture had mehlich 3-extractable Zn concentrations up to 300 mg dm with no corresponding increase in soil cu; two soil mixtures had soil Zn concentration up to 400and 800 mg dm with a corresponding increase in soil Cu up to 20 and 25 mg dm, respectively; and four soil mixtures had no increase in soil Zn, but had mehlich 1-extractable Cu concentrations from 6 to 286 mg kg. Under a given set of greenhouse conditions, the estimated mehlich 3-extractable Zn CTL was 36 mg dm for peanut, 70 mg dm for soybean, between 160 and 320 mg dm for rice, and > 300 mg dm for corn. No soil Cu CTL was apparent for peanut or soybean but for corn it was 17 mg dm and for rice 13 mg dm. With different greenhouses procedures and the Mehlich 1 extractant, the soil CTL for rice was only 4.4 mg kg. Therefore, peanut and soybean were more sensitve to Zn toxicity, whereas corn and rice were more sensitive to Cu toxicity. Plant Zn CTL for peanut was 230 mg kg, while that for soybean was 140 mg kg. Copper appeared to be toxic to corn and rice at plant concentrations exceeding 20 mg kg. |
