ABSTRACT.
This study aimed to characterize the embryotoxic, teratogenic and abortifacient effect of Poincianella pyramidalis in goats. Twenty pregnant goats with 18 days of gestation were
divided into five groups of four animals each. After collection, the leaves of P. pyramidalis were dried in the shade and crushed. The daily feed provided to the goats was equivalent to 3% of their body weight, being 1% concentrated feed and 2% roughage. In Group 1 (control), the provided roughage was Cynodon dactylon (Tifton) hay; in Groups 2, 3 and 4, 10%, 20% and
80% of the C. dactylon roughage was replaced by dry and ground P. pyramidalis, respectively. In Group 5, all the roughage was replaced by green P. pyramidalis ad libitum, collected daily.
Ultrasonographic examination was performed twice a week throughout the pregnancy. Goats in Groups 1, 2 and 3, delivered normal kids. Two goats in Group 4 aborted at 127 and 90 days
of gestation. In group 5, three goats showed embryonic death at 25, 30 and 31 days of gestation and the other goat aborted at 39 days of pregnancy. Malformations were not observed. It is
suggested that P. pyramidalis, which is very common in the semiarid region of northeastern Brazil, should be considered as an important cause of reproductive losses in this area. Due to
its high palatability, it is important to avoid the ingestion of P. pyramidalis by pregnant and mating goats.

RESUMO.
O objetivo deste trabalho foi estudar o potencial embriotóxico, abortivo e teratogênico da Poincianella pyramidalis em caprinos. Para tanto foram utilizadas 20 cabras prenhes com 18 dias de gestação, divididas em cinco grupos de quatro animais. Depois da coleta, as folhas de P. pyramidalis era secas a sombra e trituradas. A alimentação diária fornecida aos caprinos foi proporcional a 3% do seu peso vivo, sendo 1% de alimento concentrado e 2% de volumoso. No Grupo 1 (controle), o volumoso fornecido foi apenas feno de Cynodon dactylon (Tifton). Já nos Grupos 2, 3 e 4, 10%, 20% e 80% do volumoso foi substituído por folhas secas e trituradas de P. pyramidalis, respectivamente. No Grupo 5, todo o volumoso foi constituído por P. pyramidalis verde ad libitum, coletadas diariamente. Para o acompanhamento das gestações, exames ultrassonográficos foram realizados duas vezes por semana, durante toda a gestação. As cabras dos Grupos 1, 2 e 3 pariram cabritos normais. Duas cabras no Grupo 4 abortaram, sendo uma com 127 dias de gestação e outra com 90 dias. No grupo 5, três cabras apresentaram morte embrionária no 25º, 30º e 31º dia de gestação e uma cabra abortou no 39º dia de gestação. No presente estudo não foi observada nenhuma malformação. Com esses resultados e considerando a ampla difusão de P. pyramidalis na região semiárida do nordeste Brasileiro sugere-se que esta planta é uma importante causa de perdas reprodutivas na região. Devido a sua alta palatabilidade, recomenda-se evitar a permanência de cabras prenhes em áreas onde ocorre P. pyramidalis. MenosABSTRACT.

Abstract:
Barley yellow dwarf (BYD) is one of the major viral diseases of cereals. Phenotyping BYD in wheat is extremely challenging due to similarities to other biotic and abiotic stresses. Breeding for resistance is additionally challenging as the wheat primary germplasm pool lacks genetic resistance, with most of the few resistance genes named to date originating from a wild relative species. The objectives of this study were to, i) evaluate the use of high-throughput phenotyping (HTP) from unmanned aerial systems to improve BYD assessment and selection, ii) identify genomic regions associated with BYD resistance, and iii) evaluate genomic prediction models ability to predict BYD resistance. Up to 107 wheat lines were phenotyped during each of five field seasons under both insecticide treated and untreated plots. Across all seasons, BYD severity was lower with the insecticide treatment and plant height (PTHTM) and grain yield (GY) showed increased values relative to untreated entries. Only 9.2% of the lines were positive for the presence of the translocated segment carrying resistance gene Bdv2 on chromosome 7DL. Despite the low frequency, this region was identified through association mapping. Furthermore, we mapped a potentially novel genomic region for resistance on chromosome 5AS. Given the variable heritability of the trait (0.211 ? 0.806), we obtained relatively good predictive ability for BYD severity ranging between 0.06 ? 0.26. Including Bdv2 on the predictive model had a large effect for predicting BYD but almost no effect for PTHTM and GY. This study was the first attempt to characterize BYD using field-HTP and apply GS to predict the disease severity. These methods have the potential to improve BYD characterization and identifying new sources of resistance will be crucial for delivering BYD resistant germplasm. MenosAbstract:
