Soil organisms play a crucial role in the terrestrial ecosystem. Plant protection products (PPPs) are known to affect soil organisms and might have negative impacts on soil functions influenced by these organisms. Little research has been performed to date on the impact of PPPs on tropical soil ecosystems. Therefore, in this study it was investigated whether the effects of the fungicide benomyl (chosen as a model substance) differ between tropical and temperate regions and whether data generated under temperate conditions can be used for the Environmental Risk Assessment (ERA) in tropical regions. The effect of benomyl on earthworms was evaluated in acute and chronic laboratory tests modified for tropical conditions. These tests were performed at two temperatures (20ºC and 28ºC) and with two strains (temperate and tropical) of the compost worm Eisenia fetida. The fungicide was spiked in two natural and two artificial soils. |

Conteúdo: |
Biological nitrogen fixation in root nodules is a process of great importance to crops of soybean [Glycine max (L.) Merr.], as it may provide the bulk of the plant?s needs for nitrogen. Legume nodulation involves several complex steps and, although studied for many decades, much remains to be understood. Results: This research aimed at analyzing the global expression of genes in soybean roots of a Brazilian cultivar (Conquista) inoculated with Bradyrhizobium japonicum CPAC 15, a strain broadly used in commercial inoculants in Brazil. To achieve this, we used the suppressive subtractive hybridization (SSH) technique combined with Illumina sequencing. The subtractive library (non-inoculated x inoculated) of soybean roots resulted in 3,210 differentially expressed transcripts at 10 days after inoculation were studied. The data were grouped according to the ontologies of the molecular functions and biological processes. Several classes of genes were confirmed as related to N2 fixation and others were reported for the first time. During nodule formation, a higher percentage of genes were related to primary metabolism, cell-wall modifications and the antioxidant defense system. Putative symbiotic functions were attributed to some of these genes for the first time. |
