| The objective of this work was to evaluate the seed inoculation with Azospirilum brasilense in corn plants under limitation of the water supply. Two assays were carried out in greenhouse conditions, using low nitrogen substrate pots. At first one, corn seeds were inoculated or not with A. brasilense and treated or not with a biostimulant (IBA+GA+KT). At the second experiment, two corn genotypes were inoculated or not with A. brasilense. In both assays, plants were submitted to limited condition of water supply at initial vegetative growth. During this period gas exchange parameters were determined at the plants. After stress period, dry matter and nitrogen content were determined in roots and above ground parts of the plants. In addition, substrate... |

| Burkholderia kururiensis is a diazotrophic bacterium originally isolated from a polluted aquifer environment and presents a high level of similarity with the rice endophyte "B. brasilensis" species. This work assessed the ability of B. kururiensis to endophytically colonize rice plantlets by monitoring different tissues of root-inoculated plants for the presence of bacterial growth in different media, electron microscopy and by 16S rDNA analysis. Observations of roots, stems and leaves of inoculated rice plantlets by electron microscopy revealed B. kururiensis colonization predominantly on root hair zones, demonstrating endophytic colonization primarily through the endodermis, followed by spreading into xylem vessels, a possible pathway leading to aerial... |
