text: In plant cells, environmental stressors promote changes in connectivity between
the cortical ER and the PM. Although this process is tightly regulated in space
and time, the molecular signals and structural components mediating these changes
in inter-organelle communication are only starting to be characterized. In this
report, we confirm the presence of a putative tethering complex containing the
synaptotagmins 1 and 5 (SYT1 and SYT5) and the Ca2+ and lipid binding protein
1 (CLB1/SYT7). This complex is enriched at ER-PM contact sites (EPCS), have slow
responses to changes in extracellular Ca2+, and display severe cytoskeleton-dependent
rearrangements in response to the trivalent lanthanum (La3+) and gadolinium (Gd3+)
rare earth elements (REEs). Although REEs are generally used as non-selective
cation channel blockers at the PM, here we show that the slow internalization
of REEs into the cytosol underlies the activation of the Ca2+/Calmodulin intracellular
signaling, the accumulation of phosphatidylinositol-4-phosphate (PI4P) at the
PM, and the cytoskeleton-dependent rearrangement of the SYT1/SYT5 EPCS complexes.
We propose that the observed EPCS rearrangements act as a slow adaptive response
to sustained stress conditions, and that this process involves the accumulation
of stress-specific phosphoinositides species at the PM.
