The authors regret the inclusion of the following errors in the originally published article. The Fig. 2 legend was incorrect and Fig. 5 was incorrectly displayed. These have been corrected below. Fig. 2 Overview of myo-inositol derived intermediary compounds in plants. Myo-inositol (Ins) can be used as a precursor to produce phosphatidylinositol (PtdIns) and its derivatives (A); inositol polyphosphates (B); and raffinose-family oligosaccharides, d-pinitol and cell wall polysaccharides (C). Note that InsP6 can be generated through two pathways: a lipid-dependent pathway (A) in which PtdIns4P or PtdIns(4,5)P2 are hydrolyzed by phospholipase C (PLC) to InsP2 or InsP3, respectively, which can be stepwise phosphorylated into InsP6 by two inositolpolyphosphate kinases, AtIpk2 and AtIpk1, and diacylglycerol (DAG), which is converted to phosphatidic acid (PA) as a signaling molecule. InsP6 generated through this pathway is believed to act as a signaling molecule to release Ca2+ from internal sources in response to environmental perturbations. However, InsP6 is also generated through a lipid-independent pathway (B) from Ins3P into higher inositol polyphosphates that are stepwise phosphorylated into InsP6 by AtIpk2 and AtIpk1. This InsP6 is considered as a phosphorus storage molecule and can also be used for producing osmoprotectants under stress conditions. InsP6 can be dephosphorylated by purple acid phosphate (AtPAP15) into lower polyphosphates.
