Abstract
Montevideo, the capital city of Uruguay, founded by Spaniards in the 18th century, and Colonia del Sacramento, established by the Portuguese in the 17th century, are sources of olive diversity. A study and analysis of this unexplored heritage was initiated 10 years ago, using morphological and molecular tools. After a primary geographical and historical survey, 360 Olea europaea fruit and leaf samples were collected. After morphological analysis of 11 stone characters, the samples could not be matched with any cultivars in databases from Mediterranean countries. When a set of 14 pairs of microsatellite primers was applied, nine different multilocus genotypes were detected that were not recorded in the databases. In agreement with the colonization process and olive tree introduction routes into South America, two groups of genotypes were distinguished: a) seven ?genetic mosaic? genotypes related to genotypes from Spain and Portugal, introduced to Uruguay in areas under Spanish control, and b) two genotypes with one of two alleles in less than 70% with molecular variants found in Hispanic and Portuguese cultivars. Because of their height and trunk size, these trees were assumed to be older. Based on this information, we conclude that Uruguay has preserved a unique and original gene pool, currently productive and adapted to local soil and climatic conditions. This pool is a heritage of global interest, suitable for commercial and cultural purposes.

ABSTRACT.
Oxidative stress occurs when oxidant production exceeds the antioxidant capacity to detoxify the reactive intermediates or to repair the resulting damage. Feed efficiency has been associated with mitochondrial function due to its impact on cell energy metabolism. However, mitochondria are also recognized as a major source of oxidants. The aim of this study was to determine lipid and protein oxidative stress markers, and gene and protein expression as well as activity of antioxidant enzymes in the liver of steers of divergent residual feed intake (RFI) phenotypes. Hereford steers (n = 111) were evaluated in post-weaning 70 days standard test for RFI. Eighteen steers exhibiting the greatest (n = 9; high-RFI) and the lowest (n = 9; low-RFI) RFI values were selected for this study. After the test, steers were managed together under grazing conditions until slaughter when they reached the slaughter body weight. At slaughter, hepatic samples were obtained, were snap-frozen in liquid nitrogen and stored at −80°C until analyses. Hepatic thiobarbituric acid reactive species and protein carbonyls were greater (P = 0.05) and hepatic 4-hydroxynonenal protein adducts tended (P = 0.10) to be greater for high- than low-RFI steers. Hepatic gene expression glutathione peroxidase 4, glutamate?cysteine ligase catalytic subunit and peroxiredoxin 5 mRNA was greater (P ≤ 0.05) and glutathione peroxidase 3 mRNA tended (P = 0.10) to be greater in low- than high-RFI steers. Hepatic protein expression and enzyme activity of manganese superoxide dismutase and glutathione peroxidase enzyme activity tended (P ≤ 0.10) to be greater for low- than high-RFI steers. High-efficiency steers (low-RFI) probably had better hepatic oxidative status which was strongly associated with greater antioxidant ability near to the oxidant production site and, therefore, reduced oxidative stress of the liver. Decreased hepatic oxidative stress would reduce maintenance requirements due to a lower protein and lipid turnover and better efficiency in the use of energy.
