HSP90 and co-chaperones: a multitaskers’ view on plant hormone biology

Donato, Martin di ; Geisler, Markus

In order to survive under ever‐changing conditions plants must be able to adaptively respond to their environment. Plant hormones and the signaling cross‐talk among them play a key role in integrating external and internal cues, enabling the plants to acclimate accordingly. HSP90 and several of its co‐chaperones are known as pleiotropic factors involved in the signaling pathways of...

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...
