Plant development regulated by cytokinin sinks.
Morphogenetic signals control the patterning of multicellular organisms. Cytokinins are mobile signals that are perceived by subsets of plant cells. We found that the responses to cytokinin signaling during Arabidopsis development are constrained by the transporter PURINE PERMEASE 14 (PUP14). In our experiments, the expression of PUP14 was inversely correlated to the cytokinin signaling readout...
متن کاملRegulation of plant growth by cytokinin.
Cytokinins are a class of plant-specific hormones that play a central role during the cell cycle and influence numerous developmental programs. Because of the lack of biosynthetic and signaling mutants, the regulatory roles of cytokinins are not well understood. We genetically engineered cytokinin oxidase expression in transgenic tobacco plants to reduce their endogenous cytokinin content. Cyto...
متن کاملMolecular mechanism of chloroplast development regulated by plant hormones
The chloroplast is a photosynthetic organelle in plant cells. The development and function of the chloroplast are regulated by plant hormones, particularly cytokinin as a positive regulator and brassinosteroid as a negative regulator. We would like to clarify the molecular mechanism of chloroplast development regulated by the two phytohormones, and attempts to clarify the mechanism using the ap...
متن کاملInhibition of Cytokinin-Regulated Responses by Calmodulin- Binding
Two classes of compous which bind to calnodulin in a calciumdependent manner (neuroleptic drugs and local anaesthetics) were used to investigate the possible involvement of a calcium-dependent regulator protein in the action of the plant hormones cytokinins. The cytokinin-induced synthesis of betacyanin in Amarandus tricolr seedlings was used as one test system. The calmodulin antagonists inhib...
