ABSTRACT:
In Eastern Uruguay there has been a significant increase of seneciosis in grazing livestock with most affected localities related to counties neighboring the Brazilian border. A survey in 28 farms associated with poisoning outbreaks in grazing cattle in Eastern Uruguay was carried out. Fifty populations of Senecio plants were collected for alkaloid analysis and species identification. Four species were identified: S. oxyphyllus DC, S. madagascariensis Poir, S. brasiliensis (Spreng.) Less., and S. selloi DC. Alkaloids were identified by a combination of GC-MS and HPLC-MS analysis and included: retrorsine in S. oxyphyllus; retrorsine, usaramine, and senecivernine/senecionine in S. selloi; retrorsine, senecivernine/senecionine, integerrimine, and usaramine in S. madagascariensis; and integerrimine, retrorsine and senecionine in S. brasiliensis. Total mean alkaloid concentration was reported to be highest in S. brasiliensis (17.6mg/g) followed by S. oxyphyllus (6.2mg/g), S. selloi (1.8mg/g) and S. adagascariensis (0.6mg/g). Alkaloid concentrations were also reported to be higher in 2015 vs. 2016 probably due to a common environmental factor. The species S. oxyphyllus and S. madagascariensis were not previously recognized as toxic plants in Eastern Uruguay. Particularly, S. oxyphyllus was present in 82% of the farms surveyed and occurred in high density with relative high concentrations of pyrrolizidine alkaloids suggesting S. oxyphyllus may be the main species involved in the reported outbreaks of seneciosis.

Abstract.
A selection of 11 microsatellite markers (SSRs) reported for fingerprinting germplasm collections of Pyrus spp. was used to genotype a collection of cultivars and rootstocks. This set of markers included the "minimum core" established by Evans et al. (2009). Cultivars with known origin ('Williams', 'Abbé Fétel' and 'Doyenné du Comice') were included as reference accessions. The comparison was performed among 44 accessions collected from old pear plantations with different commercial origins and date of introduction to the country. The aim of this study was to genotype pear accessions that were introduced in Uruguay to evaluate the genetic variability among clones and pear rootstocks. The selected markers proved to be effective for variability discrimination in all the accessions having 6 to 12 alleles per locus. The most informative markers were CH01d09, CH02b10 and GD96. Within cultivars, the observed variability among the 13 'Williams' clones could respond to the numerous introductions from different origins that were performed throughout the years of pear production in the country. Although the accessions were grouped in clearly defined clusters as expected before the analysis, they showed variability within cultivars. The accession 00LBPrSJ is a rootstock collected from the locality of San José, selected because of its medium to low vigor that leads to medium-sized fruit trees. This accession showed a particular molecular pattern profile characterized by unique alleles that make it genetically distant from other accessions. The above mentioned phenotypic feature represents a very appealing condition, that is suitable for the current cultivation practices overcoming incompatibility problems.
