Role of rhizosphere microorganisms in growth of plants in soils with low P availability

与植物和土壤生物的需求相比，许多澳大利亚土壤中有效磷的浓度较低。植物基因型在低磷有效度下的生长能力不同，但根际微生物在植物从这种土壤中吸收磷方面的作用在很大程度上是未知的。我们将确定根际微生物在不同作物基因型和不同澳大利亚低磷土壤中本地植物物种的磷溶解和动员中的作用。研究结果将全面揭示根际微生物生态在作物和原生植物磷吸收中的作用。

The concentration of available phosphorus in many Australian soils is low compared to the requirement of plants and soil organisms. Plant genotypes differ in their capacity to grow at low P availability but the role of rhizosphere microorganisms in plant P uptake from such soils is largely unknown. We will determine the role of rhizosphere microorganisms in P solubilisation and mobilisation in different crop genotypes and native plant species in different Australian soils with low P availability. The results will give a comprehensive picture of the role of rhizosphere microbial ecology in phosphorus acquisition by crop and native plants.
