NADP-malate dehydrogenase extracted from darkened leaves of the C3 plants pea, barley, wheat and spinach was activated by reduced glutathione, a monothiol, as well as by dithiothreitol (DTT). However, in the C4 plants maize and Flaveria trinervia, only dithiothreitol could effectively activate the
The activity of the enzymes catalyzing the first two steps of sulfate assimilation, ATP sulfurylase and adenosine 5'-phosphosulfate reductase (APR), are confined to bundle sheath cells in several C(4) monocot species. With the aim to analyze the molecular basis of this distribution and to determine
In the present study, we aimed to elucidate how strategies of reactive oxygen species (ROS) regulation and the antioxidant defense system changed during transition from C₃ to C₄ photosynthesis, by using the model genus Flaveria, which contains species belonging to different steps in C₄ evolution.
The evolution of C4 photosynthesis led to an increase in carbon assimilation rates and plant growth compared to C3 photosynthetic plants. This enhanced plant growth, in turn, affects the requirement for soil-derived mineral nutrients. However, mineral plant nutrition has scarcely been considered in
