Many studies have been pointing to a high diversity of bacteria associated to legume root nodules. Even though most of these bacteria do not form nodules with legumes themselves, it was shown that they might enter infection threads when co-inoculated with rhizobial strains. The aim of this work was to describe the diversity of bacterial communities associated with cowpea (Vigna unguiculata L. Walp) root nodules using 16S rRNA gene amplicon sequencing, regarding the factors plant genotype and soil type. As expected, Bradyrhizobium was the most abundant genus of the detected genera. Furthermore, we found a high bacterial diversity associated to cowpea nodules; OTUs related to the genera Enterobacter, Chryseobacterium, Sphingobacterium, and unclassified Enterobacteriacea were the most abundant. The presence of these groups was significantly influenced by the soil type and, to a lesser extent, plant genotype. Interestingly, OTUs assigned to Chryseobacterium were highly abundant, particularly in samples obtained from an Ultisol soil. We confirmed their presence in root nodules and assessed their diversity using a target isolation approach. Though their functional role still needs to be addressed, we postulate that Chryseobacterium strains might help cowpea plant to cope with salt stress in semi-arid regions. |

The objective of this paper was to identify the main producers, sellers and buyers of Brazilian sugarcane and its derivatives disaggregated by market segment size and product. This analysis focused on all supply-side actors and included mills, refineries, distributors, and traders. This research was of the descriptive type and the documental research technique was adopted as a methodological procedure. The analysis and interpretation of the results was organized in two parts, in which the first presents the main producers and sellers of Brazilian sugarcane and its derivatives. The second presents the main buyers of Brazilian sugarcane and its derivatives, disaggregated into sugar, ethanol (biofuel) and ethanol for other purposes. On the production perspective, due to climate and soil conditions, Midwest Region has been gaining prominence, although the state of São Paulo remains as the main producing region. From the sugarcane buyer point of view, the market behavior is related to the purpose for which this raw material will be used, as well as sugar, ethanol (biofuel) or ethanol for other uses. There is still the geographical concentration of the buyers, reinforcing the role of logistics. |
