The complexity of in vivo toxic effects of Cd on higher plants makes almost
impossible an accurate distinction between direct and indirect mechanisms
of its action on the photosynthetic apparatus. We, therefore, postulate tha
t multiple Cd effects on plant physiological and metabolic processes may fi
nally be focused on photosynthesis. This would also explain the phenomenon
that only a small fraction of Cd entering chloroplasts may cause such disas
trous changes in their structure and function. In return, the inhibition of
photosynthesis affects numerous metabolic pathways dependent on the primar
y carbon metabolism.
