Název v původním jazyce

Cytokinin regulation of gene expression in the AHP gene family in Arabidopsis thaliana

Popis výsledku v původním jazyce

In higher plants, histidine-aspartate phosphorelays are involved in hormone and stress signaling via two-component systems of signal transduction. In this system, a histidine-containing phosphotransmitter (HPt) mediates signal transmission from a sensoryhistidine kinase to a response regulator, providing integration and/or branching of several different signaling pathways. Five genes encoding HPts, AHP1-5, have been identified in Arabidopsis. Histidine-aspartate phosphorelays involving HPts have been at least partly implicated in cytokinin signaling. We analyzed the regulation by cytokinins of AHP gene expression. We compared the effects on steady state levels of AHP transcripts of a short-term treatment with an aromatic cytokinin and increase in endogenous isoprenoid cytokinin levels using an activable ipt system in 8-day-old Arabidopsis seedlings. Following ipt activation, a rapid and highly preferential increase in trans-zeatin-type cytokinins was observed while other isoprenoid-ty
