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.

ABSTRACT
In the present work, the effects of undernutrition of beef cows during early pregnancy on their productivity in the short, medium and long term were studied. Thus, 115 cows (Brown Mountain and Pyrenean breeds) were used and they were oestrous synchronizeted, and then managed with a protocol of fixed time artificial insemination 11 days later (76 ± 14 days postpartum). During the first third of pregnancy, cows received a diet 100% (CONTROL) or 65% (SUBNUT) of their energy requierements; the rest of the pregnancy period and during the following lactation all cows received a diet that supply 100% their requirements. The imposed maternal
undernutrition did not affect fertility (77.4%); however, undernourished cows lost live weight and body reserves during the first third of gestation. Maternal undernutrition also caused lower growth in calves that were simultaneously raising undernourishment.
Six months after the end of the maternal feeding treatment, the undernourished cows had a lower body condition at calving, which affected the majority of parameters analyzed in the cows and their offspring. All cows lost weight during the following lactation, except for the undernourished Pyrenees, who maintained their live weight; on the contrary, their calves had the lowest growth, the lowest weaning weight (21% less) and the lowest IGF-1 values (closely related to animal development).
This experiment confirmed that early maternal undernutrition has short, medium and long-term effects on cows, on calves raised and on offspring gestated during
such undernutrition. MenosABSTRACT
