Abstract:Amorimia spp. are sodium monofluoroacetate (MFA) containing plants causing sudden death in ruminants. In a previous study, Amorimia rigida caused abortion in one of the five pregnant sheep that received the plant suggesting that it may cause reproductive losses. This work aimed to study the embryotoxic and fetotoxic effects of Amorimia septentrionalis in goats in the Brazilian northeastern semi-arid region. The effects of A. septentrionalis on pregnancy were studied in 16 goats, divided into four groups according to their gestational period. In Groups 1, 2 and 3 the administration of A. septentrionalis at the daily dose of 5g of leaves per kg body weight was started on the 18th, 36th and 93th days of gestation, respectively. Goats from Group 4 did not ingest the plant. When the goats presented severe signs of poisoning the administration of the plant was suspended. Groups 1, 2 and 3 ingested the plant for 7.25±2.87, 9.25±2.21 and 12.50±0.57 days, respectively. All the goats recovered 7-12 days after the end of the administration of the plant. In Group 1, all the goats had embryonic death 6.25±3.59 days after the end of the ingestion of the plant. In Group 2, three goats aborted at 53, 54 and 78 days of gestation. Two goats from Group 3 gave birth normally and the other two aborted at 114 and 111 days of gestation. It is concluded that Amorimia septentrionalis is a sodium monofluoracetate-containing plant that causes embryonic deaths and abortions in goats that ingest non-lethal doses of the plant.
RESUMO:
Amorimia spp. são plantas que contém monofluoroacetato de sódio (MFA), responsáveis por causar morte súbita em ruminantes. Em estudo prévio, Amorimia rigida causou aborto em uma de cinco ovelhas prenhas que receberam a planta, sugerindo que pode causar perdas reprodutivas. Este trabalho teve como objetivo estudar os efeitos embriotóxicos e fetotóxicos de Amorimia septentrionalis em caprinos na região semi-árida nordestina brasileira. Os efeitos de A. septentrionalis na prenhez foram estudados em 16 cabras, divididos em quatro grupos de acordo com seu período gestacional. Nos grupos 1, 2 e 3 a administração de A. septentrionalis foi diária, na dose de 5g de folhas por kg de peso corporal, iniciada nos dias 18, 36 e 93 da gestação, respectivamente. As cabras do grupo 4 não ingeriram a planta. Quando as cabras apresentavam sinais severos de intoxicação suspendia-se a administração da planta. Os grupos 1, 2 e 3 ingeriram a planta por 7,25±2,87, 9,25±2,21 e 12,50±0,57 dias, respectivamente. Todas as cabras se recuperaram 7-12 dias após o final da administração da planta. No grupo 1, todas as cabras apresentaram quadros de mortalidade embrionária 6,25±3,59 dias após o término da ingestão da planta. No grupo 2, três cabras abortaram aos 53, 54 e 78 dias de gestação. Duas cabras do Grupo 3 deram à luz normalmente e as outras duas abortaram aos 114 e 111 dias de gestação. Conclui-se que Amorimia septentrionalis é uma planta que contém monofluoroacetato de sódio e pode ocasionar mortes embrionárias e abortos em cabras que ingerem doses não letais da planta MenosAbstract:Amorimia spp. are sodium monofluoroacetate (MFA) containing plants causing sudden death in ruminants.

ABSTRACT.
Synthetic pesticides have a positive impact on food production. However, there are concerns due to the outbreak of resistance along with negative side effects on human health and the environment. New active compounds and control strategies are needed for the management of phytopathogens. Antimicrobial peptides (AMPs) are evolutionarily conserved components of the innate immune response in almost all organisms that constitute an
interesting source of potential molecules for use as pesticides. The naturally derived antimicrobial peptide Aq- AMP (Amaranthus quitensis-Antimicrobial Peptide), obtained from Amaranthus quitensis, is cysteine-rich with activity against several phytopathogens. In the present work, we report on the expression in Escherichia coli of functionally active Aq-AMP fused to thioredoxin (TrxAq-AMP). The in vitro antifungal activity of purified TrxAq-AMP
was confirmed against Alternaria solani, Fusarium oxysporum f. sp. lycopersici, Pencillium digitatum and P. italicum, as well as the in vivo control of P. digitatum in oranges. We demonstrated the stability of TrxAq-AMP in a range of pH (from 3 to 11) and at temperatures from 0°C to 100°C. Furthermore, it maintained activity after digestion with various proteases and it displayed no haemolytic activity suggesting a highly stable and safe molecule. For
topical application we present AMP with no haemolytic/phytotoxic activity that is effective, stable to a wide range of temperature and pH, and resistant to protease activity. Besides, this molecule is naturally stored in the seed, easy to extract and potentially produced through molecular farming. These findings encourage further biotechnological research on topical application of AMPs, especially in relation to molecule bioavailability. MenosABSTRACT.
