Response to oxidative stress induced by cadmium and copper in tobacco plants (N...
Martins, LuÃsa Louro; Mourato, Miguel P.; Baptista, Sérgio; Reis, Rafaela; Carvalheiro, Florbela; Almeida, André M.; Fevereiro, Pedro; Cuypers, AnnThe response of tobacco plants genetically engineered with the AtTPS1 gene to stress induced by excess Cu and Cd was evaluated in hydroponic solution (100 and 400 lM Cu and 50 and 200 lM Cd) after a 48 h exposure. Two transgenic lines, transformed with the AtTPS1 (trehalose-6-phosphate synthase) gene from Arabidopsis, with different levels of trehalose-6-phosphate synthase expression (B5H, higher and B1F, lower...

Oliva, Abel; Fevereiro, Pedro; Vaz Patto, Carlota; Maycock, Christopher; Malho, Rui; Tomaz, Leonor; Miguel, Ana; Santos, AnaAbstract Background: Nanotechnology has the potential to provide agriculture with new tools that may be used in the rapid detection and molecular treatment of diseases and enhancement of plant ability to absorb nutrients, among others. Data on nanoparticle toxicity in plants is largely heterogeneous with a diversity of physicochemical parameters reported, which difficult generalizations. Here a cell biology app...
