Image techniques: New approaches in metal homeostasis

Abstract

Plant physiological processes take place in a complex cellular environment. Organs are complex structures made up of different tissues with distinct cell types. Traditional biochemistry involves the analysis of bulk samples containing a mixture of heterogeneous tissues, leading to a non correct interpretation of the results. This averaging effect can only be over come by increasing the spatial resolution of analysis to a tissue -or even cell- specific level, in other words, by using image techniques.
