Abstract

The endoplasmic reticulum (ER) is a dynamic subcellular compartment that is essential to eukaryotic life because it contributes significantly to the synthesis of fundamental building blocks of the cell, including proteins and lipids, and it acts as an important architectural scaffold to maintain a well-organized spatial distribution of the other endomembrane organelles. Recent analyses with live cell imaging coupled with genetics studies have brought to light the incredible dynamism of this organelle and the underlying drivers as well as the impact of the ER organization on the general cellular homeostasis and plant growth. In this review, we highlight the most recent advances in the understanding of the mechanisms that enable the morphological integrity of the plant ER in relation to the other organelles and the cytoskeleton. The endomembrane system comprises endocytic and biosynthetic cellular processes that are closely integrated. At the core of the endomembrane system lies the ER, an essential and largely pleiotropic organelle. With its network of interconnected tubules and flattened cisternae, the ER represents the organelle with the largest membrane surface area and can be considered as the gatekeeper of the secretory pathway that controls multiple checkpoints in protein biosynthesis: folding, quality control, signaling, and degradation.

Furthermore, with its function in controlling protein synthesis and folding, the ER has an important role in abiotic and biotic stress resistance through the unfolded protein response signaling (Angelos et al., 2017). The ER also is an important cellular compartment for calcium storage and carbohydrate metabolism (Vitale and Denecke, 1999; Vitale and Galili, 2001).},

Endomembrane Cation Transporters and Membrane Trafficking

Technical Report Sze, Heven

Multicellular, as well as unicellular, organisms have evolved mechanisms to regulate ion and pH homeostasis in response to developmental cues and to a changing environment. The working hypothesis is that the balance of fluxes mediated by diverse transporters at the plasma membrane and in subcellular organelles determines ionic cellular distribution, which is critical for maintenance of membrane potential, pH control, osmolality, transport of nutrients, and protein activity. An emerging theme in plant cell biology is that cells respond and adapt to diverse cues through changes of the dynamic endomembrane system. Yet we know very little about the transporters that mightmore »« less

Interaction between VPS35 and RABG3f is necessary as a checkpoint to control fusion of late compartments with the vacuole

Journal Article Rodriguez-Furlan, Cecilia ; Domozych, David ; Qian, Weixing ; ... - Proceedings of the National Academy of Sciences of the United States of America

Vacuoles are essential organelles in plants, playing crucial roles, such as cellular material degradation, ion and metabolite storage, and turgor maintenance. Vacuoles receive material via the endocytic, secretory, and autophagic pathways. Membrane fusion is the last step during which prevacuolar compartments (PVCs) and autophagosomes fuse with the vacuole membrane (tonoplast) to deliver cargoes. Protein components of the canonical intracellular fusion machinery that are conserved across organisms, includingArabidopsis thaliana, include complexes, such as solubleN-ethylmaleimide–sensitive factor attachment protein receptors (SNAREs), that catalyze membrane fusion, and homotypic fusion and vacuole protein sorting (HOPS), that serve as adaptors which tether cargo vesicles to targetmore »« less

The plant endoplasmic reticulum: an organized chaos of tubules and sheets with multiple functions

Journal Article Kriechbaumer, V. ; Brandizzi, F. - Journal of Microscopy

The endoplasmic reticulum is a fascinating organelle at the core of the secretory pathway. It is responsible for the synthesis of one third of the cellular proteome and, in plant cells, it produces receptors and transporters of hormones as well as the proteins responsible for the biosynthesis of critical components of a cellulosic cell wall. The endoplasmic reticulum structure resembles a spider-web network of interconnected tubules and cisternae that pervades the cell. The study of the dynamics and interaction of this organelles with other cellular structures such as the plasma membrane, the Golgi apparatus and the cytoskeleton, have been permittedmore »« less

The reticulons: Guardians of the structure and function of the endoplasmic reticulum

Journal Article Di Sano, Federica ; Bernardoni, Paolo ; Piacentini, Mauro ; ... - Experimental Cell Research

The endoplasmic reticulum (ER) consists of the nuclear envelope and a peripheral network of tubules and membrane sheets. The tubules are shaped by a specific class of curvature stabilizing proteins, the reticulons and DP1; however it is still unclear how the sheets are assembled. The ER is the cellular compartment responsible for secretory and membrane protein synthesis. The reducing conditions of ER lead to the intra/inter-chain formation of new disulphide bonds into polypeptides during protein folding assessed by enzymatic or spontaneous reactions. Moreover, ER represents the main intracellular calcium storage site and it plays an important role in calcium signalingmore »« less

Maintaining the structural and functional homeostasis of the plant endoplasmic reticulum

Journal Article Brandizzi, Federica - Developmental Cell

The endoplasmic reticulum (ER) is a ubiquitous organelle that is vital to the life of eukaryotic cells. It synthesizes essential lipids and proteins, and initiates the glycosylation of intracellular and surface proteins. As such, the ER is necessary for cell growth and communication with the external environment. The ER is also a highly dynamic organelle, whose structure is continuously remodeled through an interaction with the cytoskeleton and the action of specialized ER shapers. Recent and significant advances in ER studies have brought to light conserved and unique features underlying the structure and function of this organelle in plant cells. Excitingmore »« less
