We present unresolved questions in plant abiotic stress biology as posed by 15 research
groups with expertise spanning eco-physiology to cell and molecular biology. Common …

The plasma membrane (PM) is the biological membrane that separates the interior of all
cells from the outside. The PM is constituted of a huge diversity of proteins and lipids. In this …

Endomembrane trafficking is essential for all eukaryotic cells. The best-characterized
membrane trafficking organelles include the endoplasmic reticulum (ER), Golgi apparatus …

Cells maintain a constant dialog between the extracellular matrix and their plasma
membrane to fine tune signal transduction processes. We found that the receptor kinase …

Rho guanosine triphosphatases (GTPases) are master regulators of cell signaling, but how
they are regulated depending on the cellular context is unclear. We found that the …

Anionic phospholipids, which include phosphatidic acid, phosphatidylserine, and
phosphoinositides, represent a small percentage of membrane lipids. They are able to …

Autophagy is an intracellular degradation mechanism critical for plant acclimation to
environmental stresses. Central to autophagy is the formation of specialized vesicles, the …

Highlights•PI (4, 5) P 2 tissue-specific accumulation patterns control cell differentiation.•PI4P/
PI4Kβs accumulate at the cell plate of dividing cells and regulate cytokinesis.•PS variations …

Environmental stresses cause membrane damage in terrestrial plants. Studies on the lipids
obtained from these plants are required to understand their adaptation to climate change …

Plant cell membranes are the sites of sensing and initiation of rapid responses to changing
environmental factors including salinity stress. Understanding the mechanisms involved in …
