Since the nineteens, Uruguayan native forests have been protected by law and their utilization reduced to some scarce traditional uses if not literally left untouched in many cases. However, in the last years, discussions raised around the ecological significance and the socio-economic future of this natural patrimony and a new national strategy was designed with a quite wide stakeholders participation. In parallel, as part of a national prospective study, the government conducted a bioeconomy study, applied to both planted and native forests. Biorefinery, through the extraction of high-value molecules from non-wood products for green chemistry was identified as one of the challenging approaches to fulfill the expectations of the bioeconomy implementation in the country. This works reports the research advances obtained by the Forestry Department of the National Agricultural Research Institute (INIA-Uruguay) in the field of: (i) the identification, extraction and characterization of secondary metabolites of native forest species as a raw material for biomaterials production and (ii) the way to increase its production through high-value tree domestication for ex situ cultivation providing knowledge to improve the reproduction, growth and yield of promising forest species. Two target native forest species (Quillaja brasiliensis and Prosopis affinis) were systematically studied through an interdisciplinary agenda and with an interdisciplinary team, covering different steps from the field to the laboratory: bioprospecting, cutting and plant production in vitro, seedling propagation in nursery, laboratory extraction and characterization of secondary metabolites, industrial scaling up and diffusion and technology transfer.

Abstract:
Diversity of rhizobia nodulating Lotus corniculatus grown in geographical regions with different rainfall regimes in northern and southern Uruguay, was estimated using 168 root nodule isolates. ERIC-PCR analysis revealed no correlation between observed fingerprints and the geographical origin of isolates. Despite the commercial strain U510 has been used for decades to inoculate L. corniculatus, none of the isolates corresponded to this strain. Phylogenetic analyses using 16S rRNA and atpD genes, and ITS sequences clustered all the isolates within genus Mesorhizobium. A great majority of the isolates likely belong to the species M. huakuii, as does the commercial strain U510. The remaining isolates were closely related to either M. septentrionale or M. caraganae. Although no M. loti-like bacteria were identified, all isolates carried symbiotic genes closely related to M. loti and other narrow host range Lotus rhizobia. A significant portion of the Uruguayan isolates were as efficient as the reference strain U510 in symbiosis with L. corniculatus. A few of the isolates were also capable of nitrogen fixation in symbiosis with L. uliginosus, albeit with lower efficiency than reference strains. Our results indicate that rhizobia nodulating L. corniculatus in Uruguay are genetically and phenotypically diverse, and that the commercial strain U510 is probably not adapted to survive the Uruguayan edaphoclimatic conditions. |
