Abstract: Evolution of flooding tolerance in weedy rice has occurred in several rice-growing regions, but the genes related to this process and the environmental effects are unknown. The objective of this study was to analyse the expression of genes related to flooding tolerance in response to temperature and flooding during the initial establishment of weedy rice. The experiments were carried out with rice cultivars IRGA 417 and Nipponbare, which are sensitive to flooding, and weedy rice ITJ03 and AV04 genotypes that have high and intermediate tolerance to flooding, respectively. The expression of genes related to reserve mobilisation, anaerobic respiration, escape and quiescence strategies was analysed at periods up to 24 days after sowing. The flooding tolerance of weedy rice genotype ITJ03 was associated with the expression of RAmy3D and OsTPP7, which are involved in the mobilisation of carbohydrate reserves, ADH1 and ADH2, which participate in anaerobic respiration, and SNRKL1 that triggers rapid elongation of the coleoptile and emergence. Although the genes PDC1,SUS3 and SUB1 are important for flooding tolerance in cultivated rice, their expression was not directly related to flooding tolerance in weedy rice. A temperature of 20°C reduced levels of expression of the RAmy3D, ADH2 and SNRKL1 genes and low temperature had a negative effect on the establishment of weedy rice. Breeding of rice genotypes with tolerance of low temperatures and anaerobic conditions may be a viable strategy to improve the control of weedy rice in paddy fields.

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.
