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.
Accumulation of lycopene in citrus fruits is an unusual feature restricted to selected mutants. Grapefruit (Citrus paradisi Macf.) is the Citrus specie with greater number of red-fleshed mutants, but the molecular bases of this alteration are not fully understood. To gain knowledge into the mechanisms implicated in this alteration, we conducted a comparative analysis of carotenoid profile and of the expression of genes related to carotenoid biosynthesis and catabolism in flavedo and pulp of two grapefruit cultivars with marked differences in colouration: the white Marsh and the red Star Ruby. Mature green fruit of Marsh accumulated chloroplastic carotenoids, while mature tissues lacked carotenoids. However, accumulation of downstream products such as abscisic acid (ABA) and expression of its biosynthetic genes, 9-cis-epoxycarotenoid dioxygenase (NCED1 and NCED2), increased after the onset of colouration. In contrast, red grapefruit accumulated lycopene, phytoene and phytofluene, while ABA content and NCED gene expression were lower than in Marsh, suggesting a blockage in the carotenoid biosynthetic pathway. Expression analysis of three genes of the isoprenoid pathway and nine of the carotenoid biosynthetic pathway revealed virtually no differences in flavedo and pulp between both genotypes, except for the chromoplast-specific lycopene cyclase 2 (β-LCY2) which was lower in the pulp of the red grapefruit. The proportion in the expression of the allele with high (β-LCY2a) and low (β-LCY2b) activity was also similar in the pulp of both genotypes. Therefore, results suggest that reduced expression of β-LCY2 appears to be responsible of lycopene accumulation in the red Star Ruby grapefruit.
