Abstract: Evolution of flooding tolerance in weedy rice has occurred in several rice-growing regions, but the genes related to this process and the environmental effects are unknown. The objective of this study was to analyse the expression of genes related to flooding tolerance in response to temperature and flooding during the initial establishment of weedy rice. The experiments were carried out with rice cultivars IRGA 417 and Nipponbare, which are sensitive to flooding, and weedy rice ITJ03 and AV04 genotypes that have high and intermediate tolerance to flooding, respectively. The expression of genes related to reserve mobilisation, anaerobic respiration, escape and quiescence strategies was analysed at periods up to 24 days after sowing. The flooding tolerance of weedy rice genotype ITJ03 was associated with the expression of RAmy3D and OsTPP7, which are involved in the mobilisation of carbohydrate reserves, ADH1 and ADH2, which participate in anaerobic respiration, and SNRKL1 that triggers rapid elongation of the coleoptile and emergence. Although the genes PDC1,SUS3 and SUB1 are important for flooding tolerance in cultivated rice, their expression was not directly related to flooding tolerance in weedy rice. A temperature of 20°C reduced levels of expression of the RAmy3D, ADH2 and SNRKL1 genes and low temperature had a negative effect on the establishment of weedy rice. Breeding of rice genotypes with tolerance of low temperatures and anaerobic conditions may be a viable strategy to improve the control of weedy rice in paddy fields.

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.
