General Information

General Information Comment Organism
metabolism IPT catalyzes the rate-limiting step for the addition of dimethylallyl diphosphate to the N6 of 5-AMP to form isopentenyl AMP, which is the precursor of isoprenoid cytokinins Manihot esculenta
additional information transgenic IPT overexpressing line 529-28 shows significant drought tolerance, significantly delayed leaf senescence syndrome compared to wild-type plants, and accumulation of a high level of trans-zeatin-type cytokinins particularly of corresponding storage O-glucosides to maintain cytokinin homeostasis. Induced expression of IPT had effects on photosynthesis, sugar allocation and nitrogen partitioning, overview, phenotypes overview Manihot esculenta
