The present investigation was conducted to examine the comparative ability of six Stylosanthes species to tolerate acid soil infertility factors with particular reference to aluminium. Initially, a pot experiment was conducted to identify those factors limiting the growth of Stylosanthes in three acid soils from south east Queesland. All six species responded positively to lime appplication in the three soils, while responses to phosphate application varied with soils, species and lime rates. Lowest dry matter yield in the unlimed soils was associated with solution aluminium concentrations in the saturation extract ranging from 37 to 55 micrometros. Maximum growth of species occurred when the solution aluminium concentrations were reduced to the range 17 to 22 micrometros by the highest lime rates, which reduced the aluminium saturation of the effective CEC to less than 5 percent in all three soils. The growth response to lime was attribured to the alleviation of aluminium toxicity. Subsequent experiments conducted using sand culture showed that aluminium could restrict the growth of Stylosanthes species both through effects on host plant qrowth and on the development of an effective legume-Rhizobium symbiosis. However, plant qrowth was shown to be considerabily more tolerant to aluminium toxicity when supplied with adequate combined nitrogen than when dependent on symbiotic nitrogen fixation. The greater sensitivity to aluminium toxicity of plants dependent on symbiotic nitrogen fixation was shown to be due.....

The rocky, seasonally-dry and nutrient-impoverished soils of the Brazilian campos rupestres impose severe growth-limiting conditions on plants. Species of a dominant plant family, Velloziaceae, are highly specialized to low-nutrient conditions and seasonal water availability of this environment, where phosphorus (P) is the key limiting nutrient. Despite plant-microbe associations playing critical roles in stressful ecosystems, the contribution of these interactions in the campos rupestres remains poorly studied. Here we present the first microbiome data of Velloziaceae spp. thriving in contrasting substrates of campos rupestres. We assessed the microbiomes of Vellozia epidendroides, which occupies shallow patches of soil, and Barbacenia macrantha, growing on exposed rocks. The prokaryotic and fungal profiles were assessed by rRNA barcode sequencing of epiphytic and endophytic compartments of roots, stems, leaves and surrounding soil/rocks. We also generated root and substrate (rock/soil)-associated metagenomes of each plant species. We foresee that these data will contribute to decipher how the microbiome contributes to plant functioning in the campos rupestres, and to unravel new strategies for improved crop productivity in stressful environments. |
