C Tracer Evidence for Synthesis of Choline and Betaine via Phosphoryl Base Intermediates in Salinized Sugarbeet Leaves.

abstract：:A screening procedure for identifying Cd-sensitive mutants of Arabidopsis thaliana is described. With this procedure, two Cd-sensitive mutants were isolated. These represent independent mutations in the same locus, referred to as CAD1. Genetic analysis has shown that the sensitive phenotype is recessive to the wild ty...
