A shot in the seed for landcare.(growth of some native shrubs boosted by nitrogen-fixing microbes)(Brief Article)

Ecologists have identified elite strains of nitrogen-fixing microbes that boost the growth of native shrubs used in revegetation projects. They are preparing to trial their application in a range of environments in southern Australia.

Dr Jeremy Burdon, of the Centre for Plant Biodiversity Research at CSIRO Plant Industry, says little known native rhizobia form mutually beneficial associations with native legumes throughout Australia. Living in nodules on the host plant's...

Australian Journal of Soil Research ; Introduction In south-western Australia, subterranean clover (Trifolium subterraneum L.) has been used as a pasture legume for many years (Chatel and Parker 1973; Chatel et al. 1973). As subterranean clover is not native to Australia, there are typically no native rhizobia present in uncultivated

Crop Science ; IT IS WELL KNOWN that the addition of lime to acidic soils increases the nodulation and growth of legumes. Inhibition of plant growth by acidic soils involves a complex interaction of soil conditions that include low pH and Ca and high available levels of Al and Mn (Foy, 1984). There is evidence
Advances in rhizobium research
Critical Reviews in Plant Sciences ; ABSTRACT: Rhizobia are well known for their capacity to establish a symbiosis with legumes. They inhabit root nodules, where they reduce atmospheric nitrogen and make it available to the plant. Biological nitrogen fixation is an important component of sustainable agriculture, and rhizobial
A new gene that controls root nodulation in chickpea.
Crop Science ; Nonnodulating genotypes of legumes are useful as nonfixing references in studies quantifying biological [N.sub.2] fixation (BNF). Davis et al. (1985) first reported gamma ray-induced nonnodulating mutants PM 233, PM 665, and PM 679 in chickpea. Later, they assigned gene symbols rn1, rn2, and rn3
Phytoremediation in the Tropics-The Effect of Crude Oil on the Growth of Tropical Plants
Bioremediation Journal ; ABSTRACT Phytoremediation is a nondestructive, cost-effective in-situ technology to clean up contaminated soils. In the case of contamination with petroleum hydrocarbons, plants enhance microbial degradation of the contaminant in the rhizosphere. The potential of this technology for the tropics
Ability of cold-tolerant plants to grow in hydrocarbon-contaminated soil
International Journal of Phytoremediation ; ABSTRACT Phytoremediation of hydrocarbons in soil involves plants and their associated microorganisms. Differences in environmental conditions and restrictions on species importation mean that each country may need to identify indigenous plants to use for phytoremedation. Screening plants for
Secondary Invasion Following the Reduction of Coronilla varia (Crownvetch) in Sand Prairie

The presence of C. varia significantly increased soil nitrogen availability and significantly decreased native species
