Abstract:
Pear flower bud necrosis (PFBN) has been observed in Uruguayan orchards affecting the productivity of the trees. Severity of the problem is highly variable across years and despite the fact that it is observed in several countries, the etiology of the disease is not always clear. To elucidate the cause of PFBN, different activities were implemented over several years: surveys of pear orchards to quantify PFBN severity, morphological and histological studies of diseased buds, and isolation of potential pathogenic microorganisms from affected tissues. From the orchard surveys no clear association between climatic conditions (mean temperatures, precipitation, chilling hours) and PFBN were detected for the five years evaluated. Flower buds collected one month before flowering and fixed in formalin-ethanol-acetic acid solution showed necrosis associated with tumour development in bud primordia, and histological preparations from those tumours showed cell hypertrophy and hyperplasia. Finally, from the diseased buds we consistently isolated bacteria and no fungi. The bacteria were gram negative, oxidase positive, fluorescent on King B medium, produced indole-3-acetic acid and were positive in the tobacco hypersensitivity test. We sequenced the 16S RNA genes of the isolated bacteria to perform a taxonomic classification. We conclude that PFBN in Uruguay is caused by bacteria belonging to the Pseudomonas genus.

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.
