The pathways for the synthesis of nucleotides in plant cells are similar to those found in animals and microorganisms.
Moreover, of the research that has been done in this area relatively little has used genetic analysis to evaluate the function(s) of specific enzymes.
This conclusion is based primarily on the results of studies using in vivo radiotracers, specific inhibitors of nucleotide synthesis and on analyses of the kinetic parameters of purified enzymes involved in nucleotide synthesisthat are unlikely to have similar demands for purine and pyrimidine nucleotides have been used in this research
