High level of endogenous cytokinins in transgenic potato plantlets limits photosynthesis

Introduction of the gene for cytokinin synthesis into potato genome lead to a manifold increase in the level of cytokinins (zeatin, zeatin riboside, isbpentenyl-adenine, isopentenyladenosine) in plantlets grownin vitro.The increasing cytokinin level was associated with increasing tendency to teratoma formation, to decreasing leaf net photosynthetic rate and… CONTINUE READING
