Manganese accumulation in rice: implications for photosynthetic functioning.
In order to gain fundamental insights into the nature of the adaptation to Mn excess, the characterisation of the photosynthetic apparatus in Mn-treated rice was carried out in 21-day-old plants. WeExpand

Effects of aluminum toxicity on nutrient accumulation in maize shoots: Implications on photosynthesis
Abstract The physiological characterization of aluminum (Al) toxicity in C4 plants prompted this study, having maize (Zea mays cv. XL‐72.3) used as a test system. Two weeks after germination, maizeExpand

Decay of the Chloroplast Pool of Ascorbate Switches on the Oxidative Burst in UV‐B‐Irradiated Rice
A parallel was drawn between UV-B irradiation and the oxidative burst in the chloroplast lamellae of rice plants (Oryza sativa L. cv. Safari). After irradiation with a total biological effective UV-BExpand

Oxy radicals production and control in the chloroplast of Mn-treated rice
The interactions between Mn accumulation and production and control of oxy radicals were investigated in rice (Oryza sati6a L. cv. Safari) chloroplasts. Rice plants were grown for 21 days in nutrientExpand
