SUMMARY.
Several Diaporthe species are recognized as causal agents of many plant disease symptoms, including twig and branch cankers, dieback, shoot blight, and root and fruit rots. In Uruguay, the proximity between apple, pear and peach orchards offers the possibility to study the presence of different Diaporthe spp. associated with
wood cankers across different deciduous fruit trees. Symptomatic twigs and branches of these orchard species were sampled, and isolates of Diaporthe were obtained. Selected isolates were used for cross inoculations in the three hosts. Seven Diaporthe spp. were identified, based on the internal transcribed spacer (ITS) region of rDNA and the translation elongation factor 1-alpha gene (EF1-α) phylogenies. The species were: Diaporthe amygdali, D. foeniculina, D. infecunda, D. eres, D. terebinthifolii, D. oxe and D. phaseolorum, while two isolates Diaporthe sp. 1 and Diaporthe sp. 4 could not be assigned to any species. Diaporthe infecunda, D. eres, D. terebinthifolii, D. phaseolorum and D. oxe on Pyrus communis and D. foeniculina on Malus domestica represent new records in these hosts in Uruguay, while D. oxe isolated from Prunus persica is a new record for this species. Diaporthe eres and D. phaseolorum were the most virulent species, posing the greatest risk due to their wide distribution and virulence in apple and peach trees. Although pear trees showed less symptomatic tissues and were less susceptible than peach and apple trees in the pathogenicity tests, they harboured seven of the species, and therefore should be considered as reservoirs of Diaporthe in Uruguayan orchards. Trees of the three hosts could be considered potential reciprocal sources of pathogenic Diaporthe spp.

Summary:
Nosema apis and Nosema ceranae are causative agents of Nosemosis in the honey bee Apis mellifera, although N. ceranae may cause a more
virulent disease. Selection of colonies with high tolerance to N. ceranae could be important for reducing problems caused by this pathogen.
The aim of the present work was to evaluate the existence of honey bee colonies with different degrees of N. ceranae infection and test if this
difference could be related to the immune response or vitellogenin expression. Healthy honey bee colonies were relocated to a plantation of
Eucalyptus grandis to favour natural infection of N. ceranae. Fifteen and thirty days after relocation, the proportion of infected bees and the
number of N. ceranae spores per field were quantified. The colonies with higher and lower levels of infection (HL and LL, respectively) were
selected. Newly emerged bees from both colonies were artificially infected with N. ceranae and seven days after infection the expression of
immune related genes and vitellogenin was evaluated by real time PCR. No significant differences were observed in expression of abaecin,
hymenoptaecin, defensin, glucose dehydrogenase or lysozyme mRNA levels between infected bees from HL and LL colonies or between
control bees from both colonies. Vitellogenin expression was higher in bees from the LL colony than in bees from the HL colony, when
infected or control bees were compared between them. This protein possesses pleiotropic effects and is a central element in the life-history of
honey bees. For that reason, its differential expression could be associated with resistance to N. ceranae.
Resumen:
Nosema apis y Nosema ceranae son agentes causales de Nosemosis en la abeja Apis mellifera aunque N. ceranae podría causar una
enfermedad más virulenta. La selección de colonias resistentes a N. ceranae podría ser importante para la reducción de problemas
ocasionados por este patógeno. El objetivo del presente trabajo fue evaluar la existencia de colonias con diferente grado de infección por N.
ceranae y evaluar si esta diferencia podría estar relacionada a la respuesta inmune o a la expresión de vitelogenina. Colonias de abejas sanas
fueron trasladadas a forestaciones de Eucalyptus grandis para favorecer la infección natural con N. ceranae. A los 15 y 30 días después del
traslado, la proporción de abejas infectadas y el número de esporas de N. ceranae por campo fueron cuantificados. Las colonias con mayor y
menor nivel de infección (HL y LL respectivamente) fueron seleccionadas. Abejas recientemente nacidas de ambas colonias se infectaron
artificialmente con N. ceranae y siete días después de la infección se evaluó la expresión de genes relacionados con inmunidad y vitelogenina,
mediante PCR en tiempo real. No se encontraron diferencias significativas en la expresión de abaecina, himenoptecina, defensina, glucosa
deshidrogenasa o lisozima entre abejas infectadas de las colonias HLy LL o entre abejas control de ambas colonias. La expresión de
vitelogenina resultó más baja en abejas pertenecientes a la colonia LL que en abejas pertenecientes a la colonia HL, cuando se compararon
abejas infectadas o abejas control. Esta proteína posee efectos pleiotrópicos y es central en la vida de las abejas melíferas, por esta razón, su
expresión diferencial podría estar asociada a la resistencia a N. ceranae. MenosSummary:
