The transcriptional mechanism behind <i>Mimosa pudica</i> leaf folding in response to mechanical disturbance Open
Mimosa pudica is a plant known for its ability to fold leaves in response to mechanical disturbances, which serves as a visible phenotypic stress marker. Leaf folding occurs with a response timing and intensity that varies depending on the…

ER-associated VAP27-1 and VAP27-3 proteins functionally link the lipid-binding ORP2A at the ER-chloroplast contact sites Open
The plant endoplasmic reticulum (ER) contacts heterotypic membranes at membrane contact sites (MCSs) through largely undefined mechanisms. For instance, despite the well-established and essential role of the plant ER-chloroplast interactio…

Going cresyl for plant cell imaging Open
The advent of fluorescent probes and the characterization of their photochemical properties in the past years allowed significant advances in the studies of spatiotemporal cellular processes within complex and crowded systems. Dyes are ind…

Actin and Microtubules Differently Contribute to Vacuolar Targeting Specificity during the Export from the ER Open
Plants rely on both actin and microtubule cytoskeletons to fine-tune sorting and spatial targeting of membranes during cell growth and stress adaptation. Considerable advances have been made in recent years in the comprehension of the rela…

Phosphoglucoisomerase Is an Important Regulatory Enzyme in Partitioning Carbon out of the Calvin-Benson Cycle Open
Phosphoglucoisomerase (PGI) isomerizes fructose 6-phosphate (F6P) and glucose 6-phosphate (G6P) in starch and sucrose biosynthesis. Both plastidic and cytosolic isoforms are found in plant leaves. Using recombinant enzymes and isolated chl…

Variation in Membrane Trafficking Linked to SNARE AtSYP51 Interaction With Aquaporin NIP1;1 Open
SYP51 and 52 are the two members of the SYP5 Qc-SNARE gene family in Arabidopsis thaliana. These two proteins, besides their high level of sequence identity (85%), have shown to have differential functional specificity and possess a differ…

Salicylic acid-independent role of NPR1 is required for protection from proteotoxic stress in the plant endoplasmic reticulum Open
Significance The biosynthetic ability of the endoplasmic reticulum (ER) is essential to eukaryotic life. Disruption of such ability ignites ER stress, a potentially lethal condition. Known sensors perceive and respond to ER stress, but how…

Plant Endocytosis Requires the ER Membrane-Anchored Proteins VAP27-1 and VAP27-3 Open
Through yet-undefined mechanisms, the plant endoplasmic reticulum (ER) has a critical role in endocytosis. The plant ER establishes a close association with endosomes and contacts the plasma membrane (PM) at ER-PM contact sites (EPCSs) dem…

SYP73 Is a Novel Membrane‐Associated Actin‐Binding Protein that Anchors the ER to the Actin Cytoskeleton in Arabidopsis Open
The endoplasmic reticulum (ER) is an essential organelle that spreads throughout the cytoplasm and undergoes extensive remodeling. In plants, the remodeling and motility of the ER rely mainly on actin and to a minor extent on microtubules.…
