This study identifies PI4P signaling and ER-PM contact sites as regulators of polarized root hair growth in plants, showing SAC7 modulates SYT1 dynamics to control cell elongation.

The paper identifies DGK1 and DGK2 as forming a module with SYT1 at ER-PM contact sites in Arabidopsis, enhancing PI cycle efficiency through DAG transport and phosphorylation during stress.

This study identifies distinct biological roles of plant synaptotagmins, showing SYT1 and SYT3 are involved in abiotic stress resistance while SYT5 is linked to pathogen resistance.

The paper shows that synaptotagmins maintain diacylglycerol homeostasis at ER-PM contact sites during abiotic stress by preventing its detrimental accumulation at the plasma membrane.
