- Induction of cadmium-binding peptides in sorghumPublication . Pinto, Ana Paula Honrado; Serafim, Angela; Bebianno, Maria; Almeida Mota, Ana MariaHydroponic experiments with sorghum were carried out in nutrient solution medium, under controlled environmental conditions for different periods of time. Cadmium (Cd ) was added at a final concentration of 0.1, 1 and 10 mg dm−3. The effect of time and cadmium concentration on the content of thiolic groups (TSH) in the “cell sap” of sorghum tissues are discussed in relation to plant resistance/tolerance to metal stress. The increase in Cd level in the nutrient solution was associated with a higher total Cd accumulation in the plant (root and shoot), which produced a significant enhancement on the thiolic groups content. Furthermore, higher Cd concentrations in plant tissues induced not only an increase in sulphur-rich compounds but also enhanced the binding capacity of these compounds.
- Os efeitos adversos da atividade humana na Ria FormosaPublication . Bebianno, Maria; Pedro, Patricia; Serafim, Angela; Lopes, Belisandra; Newton, AliceA Ria Formosa é um sistema lagunar que apresenta uma grande diversidade e complexidade estrutural, fornecendo serviços e benefícios valiosos para a região. No entanto, a presença de substâncias perigosas constitui um motivo de preocupação, pois pode colocar em perigo este sistema, sendo necessário uma gestão adequada, que permita a redução de pressões derivadas das atividades humanas, para uma melhor sustentabilidade futura deste ecossistema.
