Cadmium is a heavy metal (HM) that inhibits plant growth and leads to death, causing great losses in yields, especially in Cd hyperaccumulator crops such as Glycine max (L.) Merr. (soybean), a worldwide economically important legume. Furthermore, Cd incorporation into the food chain is a health hazard. Oxidative stress (OS) is a plant response to abiotic and biotic stresses with an intracellular burst of reactive oxygen species (ROS) that causes damage to lipids, proteins, and DNA. The arbuscular mycorrhizal fungal (AMF) association is a plant strategy to cope with HM and to alleviate OS. Our aim was to evaluate the mitigation effects of mycorrhization with AMF Rhizophagus intraradices on soybean growth, nutrients, Cd accumulation, lipid peroxidation, and the activity of different antioxidant agents under Cd (0.7–1.2 mg kg−1 bioavailable Cd) induced OS. Our results suggest that glutathione may act as a signal molecule in a defense response to Cd-induced OS, and mycorrhization may avoid Cd-induced growth inhibition and reduce Cd accumulation in roots. It is discussed that R. intraradices mycorrhization would act as a signal, promoting the generation of a soybean cross tolerance response to Cd pollution, therefore evidencing the potential of this AMF association for bioremediation and encouragement of crop development, particularly because it is an interaction between a worldwide cultivated Cd hyperaccumulator plant and an AMF–HM–accumulator commonly present in soils.

El objetivo de  este trabajo fue proporcionar los datos normativos argentinos de la serie 19 del Sistema Internacional de Imágenes Afectivas (IAPS) de Lang (Lang,  Bradley, & Cuthbert, 1997) a fin de contribuir con su validación transcultural. Los participantes fueron 125 estudiantes de la Universidad Nacional de San Luis (67% mujeres y 33% varones) que evaluaron las imágenes en las dimensiones emocionales de valencia, activación y dominancia en el Maniquí de Autorreporte (Self-Assessment Manikin-SAM). Los resultados muestran una  distribución de las imágenes en el espacio afectivo en forma de boomerang similar a lo encontrado en Estados Unidos (Lang, Bradley, & Cuthbert,  2008). No se identificaron diferencias en las dimensiones emocionales de valencia y activación, pero sí en dominancia, respecto a los datos obtenidos por Lang, Bradley y Cuthbert (2008). Esta investigación confirma que el Sistema Internacional de Imágenes Afectivas (IAPS) induce estados afectivos similares en diferentes poblaciones y que sus estímulos afectivos son entendidos de manera similar entre argentinos y estadounidenses.
