A review on the nematicidal activity of volatile allelochemicals against the pi...
Faria, Jorge M. S.; Barbosa, Pedro; Teixeira, Dora Martins; Mota, ManuelThe pinewood nematode (PWN), Bursaphelenchus xylophilus, induces shoot yellowing and wilting by injuring pine vascular tissues and resin canals. In Asia, it devastated wide forests of susceptible pine, causing drastic ecological, economic and cultural repercussions. In 1999, it reached Europe (Portugal) and despite the actions of the authorities, it rapidly advanced to the border areas of Spain, threatening the...
Synergistic Activity of Cymbopogon citratus and Mentha piperita Essential Oils ...
Gonçalves, Diogo; Cavaco, Tomás; Pombo, Ana; Moiteiro, Cristina; Teixeira, Dora Martins; Inácio, Maria L.; Faria, Jorge M.S.The pinewood nematode (PWN) Bursaphelenchus xylophilus is a major threat to pine forests. Research on sustainable pest management strategies is now a priority. Essential oils (EOs) are biodegradable, complex mixtures of volatiles that can show low toxicity to mammals and powerful nematicidal activities depending on their chemical composition. In the present work, the EOs of four plants were screened against the...
Wheat Shoot Al, Fe, Mn and Zn Levels Are Influenced by Arbuscular Mycorrhiza Ex...
Faria, Jorge M.S.; Teixeira, Dora Martins; Pinto, Ana Paula; Barrulas, Pedro; Brito, Isabel; Carvalho, MárioIn the present study, the levels of Al, Fe, Mn and Zn in wheat shoots were quantified by inductively coupled plasma mass spectrometry (ICP-MS). Wheat was grown in an acidic soil with toxic levels of Mn and with intact or disrupted extraradical mycelium (ERM) as the arbuscular mycorrhizal fungi (AMF) inoculum source, resulting from the previous growth of O. compressus. In the presence of an intact ERM, toxic Mn ...
Arbuscular Mycorrhiza Extraradical Mycelium Promotes Si and Mn Subcellular Redi...
Faria, Jorge M.S.; Conceição, Taiana A; Teixeira, Dora Martins; Brito, Isabel; Barrulas, Pedro; Pinto, Ana Paula; Vaz, Margarida; Carvalho, MárioAbstract: Manganese (Mn) and aluminum (Al) toxicities are serious edaphic limitations to crop production in acidic soils. Excess Mn can be countered using a stress-adapted soil microbiota that establish symbiotic relationships with native plants. The arbuscular mycorrhizal fungi (AMF) associated with Lolium rigidum L. develop extraradical mycelia (ERM) that quickly colonize wheat and lead to greater shoot growt...
First report on the synergistic interaction between essential oils against the ...
Faria, Jorge M. S.; Cavaco, Tomás; Gonçalves, Diogo; Barbosa, Pedro; Teixeira, Dora Martins; Moiteiro, Cristina; Inácio, Maria L.Control of the pinewood nematode (PWN), the causal agent of pine wilt disease, can be achieved through the trunk injection of nematicides; however, many pesticides have been linked to environmental and human health concerns. Essential oils (EOs) are suitable alternatives due to their biodegradability and low toxicity to mammals. These complex mixtures of plant volatiles often display multiple biological activit...
Antispasmodic activity of aqueous extracts from Mentha x piperita native from T...
Moutinho, Carla; Matos, Carla; Neves, José Manuel; Teixeira, Dora Martins; Cunha, Sílvia; Gomes, Lígia RebeloThe wild mint Mentha x piperita (Mentha rotundifolia Huds.), has been used by the local people in a northern region of Portugal to prepare infusions for treating digestive pain and spasms, as an appetite stimulant and for treating headache and migraine. This suggests that these aqueous extracts have analgesic; antispasmodic and stomachic properties. In the present study the antioxidant potential of aqueous extr...
