ABSTRACT.
Red clover (Trifolium pratense L.) is used in the improvement of grasslands in Uruguay and has been inoculated with commercial strain U204 of Rhizobium leguminosarum bv trifolii since 1970s. Native-naturalized rhizobia strains present in soil are the basis for selecting and developing new inoculants. With this aim, we evaluated the diversity of red clover rhizobia in Uruguayan red clover pastures both historically inoculated with U204 and noninoculated ones. Thirty-eight different enterobacterial repetitive intergenic consensus (ERIC) PCR genomic fingerprints were identified, albeit surprisingly only one of 80 isolates showed an ERIC profile similar to U204. Under controlled conditions, red clover plants inoculated with one of the native isolates, strain 317, produced more biomass than those inoculated with the commercial U204. ERIC-PCR was also used to show that strain 317 competed for nodulation better than U204 in a field with previous history of inoculation. Moreover, both U204 and 317 were tagged with a gusA reporter gene and their competitiveness for nodulation assessed in various soil types. Again, strain 317 appeared more competitive than U204, particularly in soils with previous history of inoculation. Our results reinforce the long-known idea of assessing the actual needs of inoculation of legumes in different soils and suggest that the indigenous isolate 317 is an effective and competitive strain that can be used for development of a new red clover inoculant.

ABSTRACT.- South American beef production varies due to diverse climates, environmental conditions, animal breeds (Bos indicus, Bos taurus and crossbreeds), management strategies, and nutritional sources. Applying technology in the South American beef production system can significantly enhance efficiency, sustainability, and profitability. Reproductive efficiency is a significant challenge, especially in cow-calf operation systems conducted under adverse conditions. Consequently, implementing effective assisted reproduction technologies (ART) can make a significant contribution. In the last two decades, the development of fixed-time artificial insemination (FTAI) protocols permitted the widespread application of artificial insemination for breeding management and genetic improvement in beef herds in South America. Nowadays, FTAI is being applied in South America in large-scale programs, with around 20 % of heifers and cows receiving this technology every year. This results in a greater calving rate and significant genetic gain occurring in this territory. Also, in vitro embryo production, mainly using sex-selected sperm has been widely applied in this region, leading to significant improvements in herd genetics and productivity. Recently, 94 % of all embryo transfers in South America consist of in vitro-produced embryos (41,429 being in vivo-derived and 650,782 being in vitro-produced embryos), mainly using fixed-time embryo transfer technology (FTET). Genomic selection combined with in vitro embryo production with oocytes from heifer calves provides a powerful technology platform to reduce generation interval and significantly increase the rate of genetic gain in beef cattle. Emerging biotechnologies, such as genome editing via the CRISPR/Cas system, are being developed to enhance productivity, confer resilience to adverse environmental conditions, increase disease resistance, and control pest species that affect livestock. Finally, while all these technologies offer significant potential, further progresses are needed to transform livestock production. The vast geographical scale and diverse climates of South America make regional knowledge crucial for aligning beef production with sustainability goals and supporting global food security. © 2024 MenosABSTRACT.- South American beef production varies due to diverse climates, environmental conditions, animal breeds (Bos indicus, Bos taurus and crossbreeds), management strategies, and nutritional sources.
