General Information

General Information Comment Organism
malfunction the ipt1357 quadruple mutant possesses severely decreased levels of isopentenyladenine and trans-zeatin , and their corresponding ribosides, ribotides, and glucosides, and is retarded in its growth. In contrast, these mutants possess increased levels of cis-zeatin-type cytokinins Arabidopsis thaliana
metabolism the enzyme isoforms are responsible for the bulk of isopentenyladenine- and trans-zeatin-type cytokinin synthesis Arabidopsis thaliana
