GA-independent DELLA regulation by inositol pyrophosphate in a nonvascular land plant - Nature Chemical Biology
A noncanonical pathway of DELLA regulation by a conserved inositol pyrophosphate synthase was identified in the liverwort, Marchantia polymorpha, that lacks the canonical gibberellin-induced DELLA deg...

The cover depicts a SEM image of a dorsal surface of liverwort M. polymorpha female thallus. Liverwort were found to have a noncanonical pathway for the regulation of master growth repressor DELLA.

Stereoselective chemoenzymatic phytate transformations provide access to diverse inositol phosphate derivatives
Phosphorylated myo-inositols (InsPs) are essential cytoplasmic signaling molecules, while their lipidated analogs (PtdInsPs) play a crucial role in membrane signaling. Stereoselective synthesis of the...
