ABSTRACT.
Herbaspirillum seropedicae is a nitrogen-fixing bacterium capable of using toxic compounds as a source of carbon. Bacteria with this capacity can be used to make animals resistant to plant poisoning containing monofluoroacetate (MFA), such as Amorimia septentrionalis. The aim of this study was to evaluate if H. seropedicae is efficient in the degradation of MFA present in A. septentrionalis and if the inoculation of this bacterium in goats confers protection to A. septentrionalis intoxication. Two experiments were performed: in the first experiment 12 goats were divided into 2 groups. Goats in Group 1 were orally administered a solution containing the H. seropedicae bacterium for 10 days. From day 10 onwards, they received a daily dose of 5g/kg of A. septentrionalis with the bacteriauntil clinical signs of intoxication were observed. Group 2 goats received only the plant at the same dose, also until the observation of clinical signs of intoxication. The amount of MFA found in A. septentrionalis used in the experiment with goats was 1.6±0.058?g/mg. The total plant dose ingested by all goats in Group 1 was 80.83±12.81g/kg (129.33±20.50mg/kg MFA), which were significantly greater (p<0.05) than those of Group 2 goats (39.16±19.08g/kg plant and 62.66±30.53mg/kg MFA). Group 1 goats took an average of 16.16±2.56 days to develop clinical signs of intoxication, significantly longer (p=0.0012) than Group 2 goats (7.83±3.81 days). Two Group 2 goats died on the same day that they developed clinical signs of intoxication. At necropsy of these two animals, no significant changes were observed. In the second experiment, samples of A. septentrionalis were sprayed with a solution containing H. seropedicae. Before and eight days after spraying, the samples were pressed and dried for quantitation of MFA. The amount of MFA present in samples of A. septentrionalis 8 days after spraying with H. seropedicae was significantly lower (p=0.017) than that found prior to spraying. It can be concluded that administration of H. seropedicae in goats is capable of causing greater resistance to A. septentrionalis intoxication, and spraying the plant with this bacterium significantly reduces the amount of MFA in the plant.

RESUMO.
Herbaspirillum seropedicae é uma bactéria fixadora de nitrogênio, capaz de utilizar compostos tóxicos como fonte de carbono. Bactérias com essa capacidade podem ser utilizadas para tornar os animais resistentes à intoxicação por plantas que contém monofluoroacetato (MFA), como Amorimia septentrionalis. O objetivo do presente estudo é avaliar se H. seropedicae é eficiente na degradação do MFA presente em A. septentrionalis e se a inoculação dessa bactéria, em caprinos, confere proteção à intoxicação por A. septentrionalis. Foram realizados dois experimentos: no primeiro experimento foram utilizados 12 caprinos, divididos em dois grupos. Os caprinos do Grupo 1 receberam diariamente, oralmente, uma solução contendo a bactéria H. seropedicae durante 10 dias. A partir do décimo dia passaram a receber, diariamente, além da solução com a bactéria 5g/kg de A. septentrionalis até a observação de sinal clínico de intoxicação. Os caprinos do Grupo 2 receberam apenas a planta na mesma dose, também até que a observação de sinais clínicos de intoxicação. A quantidade de MFA encontrada em A. septentrionalis utilizada no experimento com caprinos foi de 1,6± 0,058µg/mg de planta em média. A dose total de planta ingerida por todos os caprinos do Grupo 1 foi de 80,83±12,81g/kg (129,33±20,50mg/kg de MFA), valores significativamente maiores (p<0,05) do que os dos caprinos do Grupo 2 (39,16±19,08g/kg de planta e 62,66± 30,53mg/Kg de MFA). Os caprinos do Grupo 1 demoraram em média 16,16 ±2,56 dias para desenvolver sinais clínicos da intoxicação, período significativamente maior (p=0,0012) que os caprinos do Grupo 2 (7,83±3,81dias). Dois caprinos do Grupo 2 morreram no mesmo dia que desenvolveram sinais clínicos da intoxicação. Na necropsia desses dois animais não foram observadas alterações significativas. No segundo experimento, amostras de A. septentrionalis foram pulverizadas com uma solução contendo a bactéria H. seropedicae. Antes e oito dias após a pulverização, as amostras foram prensadas e secas para posterior quantificação do MFA. A quantidade de MFA presente nas amostras de A. septentrionalis oito dias após a pulverização com H. seropedicae foi significativamente menor (p=0,017) do que a encontrada antes da pulverização. Pode-se concluir que a administração de H. seropedicae em caprinos é capaz de causar uma maior resistência à intoxicação por A. septentrionalis, e a pulverização da planta com esta bactéria reduz significativamente a quantidade de MFA na planta.

ABSTRACT.
Apple, pear and peach orchards are usually planted in close proximity, and they might share pathogenic fungal species affecting different plant organs. In particular, species of Botryosphaeriaceae have been indicated as responsible for wood diseases in these fruit species. Symptoms frequently observed in Uruguay include papyraceous cankers in apple trunks, dead shoots in pears, and gummosis in peach shoots and branches. Symptomatic tissues of these species were sampled, and fungi resembling species within Botryosphaeriaceae were isolated and identified based on phylogenetic analysis of the internal transcribed spacer region (ITS), part of the translation elongation factor 1-α gene (EF1-α) and part of the RNA polymerase II subunit gen (RPB2). Pathogenicity of selected isolates was assessed under laboratory and field onditions. Botryosphaeria dothidea, Diplodia seriata and Neofusicoccum parvum were isolated from the three hosts from symptomatic tissues. However, only N. parvum proved to be pathogenic when inoculated on trees of all three species, while D. seriata showed pathogenicity towards apple and peach trees only. Diplodia mutila and N. australe were isolated less frequently and not from all the host species. However, they were the most virulent based on lesion length on all tested plant species. The fact that fungal isolates obtained from one host could cause disease symptoms also in some of the alternative hosts suggests that cross infections are possible between apple, pear and peach trees. Finally, Diplodia pseudoseriata in Prunus persica and Diplodia mutila in Pyrus communis, are new records for these hosts in Uruguay.
