ABSTRACT.
This review considers the use of prostaglandin F2a and its synthetic analogues (PG) for controlling the estrous cycle of the ewe. Aspects such as phase of the estrus cycle, PG
analogues, PG doses, ovarian follicle development pattern, CL formation, progesterone synthesis, ovulation rate, sperm transport, embryo quality, and fertility rates after PG
administration are reviewed. Furthermore, protocols for estrus synchronization and their success in timed AI programs are discussed. Based on available information, the ovine CL is refractory to PG treatment for up to 2 days after ovulation. All PG analogues are effective when an appropriate dose is given; in that regard, there is a positive association between the dose administered and the proportion of ewes detected in estrus. Follicular response after PG is dependent on the phase of the estrous cycle at treatment. Altered sperm transport and low pregnancy rates are generally reported. However, reports on alteration of the steroidogenic capacity of preovulatory follicles, ovulation rate, embryo quality, recovery rates, and prolificacy, are controversial. Although various PG-based protocols can be used for estrus synchronization, a second PG injection improves estrus response when the stage of the estrous cycle at the first injection is unknown. The estrus cycle after PG administration has a normal length. Prostaglandin-based protocols for timed AI achieved poor reproductive outcomes, but increasing the interval between PG injections might increase pregnancy rates. Attempts to improve reproductive outcomes have been directed to provide a synchronized LH surge: use of different routes of AI (cervical or intrauterine), different PG doses, and increased intervals between PG injections. Finally we present our point of view regarding future perspectives on the use of PG in programs of controlled sheep reproduction.

ABSTRACT.- Since 2015, a high mortality rate of strawberry plants has been observed in the north of Uruguay related to crown and root diseases caused by a pathogens complex. In 2016, associated with the death of plants, Cylindrocarpon spp. was isolated with a frequency of 42.4 %, ranking third, preceded by Neopestalotiopsis sp. and Fusarium spp. Aiming to increase the knowledge of the pathogens that integrate the complex, three isolates of Cylindrocarpon spp. were characterized by molecular, morphological and pathogenicity analyses in strawberry plants. Dactylonectria novozelandica was identified as causal agent of crown and root necrosis of strawberry in Salto, Uruguay. .-.-.-.-.-.-.-.-.-.-..-RESUMEN.- Desde 2015, se observó una alta mortandad de plantas de frutilla en el norte de Uruguay relacionada con enfermedades de corona y raíz causadas por un complejo de patógenos.
