Abstract The endosomal sorting complex required for transport-III (ESCRT-III) and VPS4 catalyze a variety of membrane-remodeling processes in eukaryotes and archaea. Common to these processes is the dynamic recruitment of ESCRT-III proteins from the cytosol to the inner face of a membrane neck structure, their activation and filament formation inside or at the membrane neck and the subsequent or concomitant recruitment of the AAA-type ATPase VPS4. The dynamic assembly of ESCRT-III filaments and VPS4 on cellular membranes induces constriction of membrane necks with large diameters such as the cytokinetic midbody and necks with small diameters such as those of intraluminal vesicles or enveloped viruses. The two processes seem to use different sets of ESCRT-III filaments. Constriction is then thought to set the stage for membrane fission. Here, we review recent progress in understanding the structural transitions of ESCRT-III proteins required for filament formation, the functional role of VPS4 in dynamic ESCRT-III assembly and its active role in filament constriction. The recent data will be discussed in the context of different mechanistic models for inside-out membrane fission.

Essential Component

Since the first description of phloem sap composition nearly 60 years ago, it is generally assumed that phloem sap does not contain nitrate and that there is little or no backflow of nitrate from shoots to roots. While it is true that nitrate can occasionally be absent from phloem sap, there is now substantial evidence that phloem can carry nitrate and furthermore, transporters involved in nitrate redistribution to shoot sink organs and roots have been found. This raises the question of why nitrate may or may not be present in phloem sap, why its concentration is generally kept low, and whether plant shoot-root nutrient cycling also involves nitrate. We propose here that phloem sap nitrate is not only an essential component of plant nutritional signaling but also contributes to physical properties of phloem sap and as such, its concentration is controlled to ensure proper coordination of plant development and nutrient transport.

Selective Elimination

: Programmed cell death (PCD) is a fundamental genetically controlled process in most organisms. PCD is responsible for the selective elimination of damaged or unwanted cells and organs to maintain cellular homeostasis during the organ’s development under normal conditions as well as during defense or adaptation to stressful conditions. PCD pathways have been extensively studied in animals. In plants, studies focusing on understanding the pathways of PCD have advanced significantly. However, the knowledge about the molecular basis of PCD is still very limited. Some PCD pathways that have been discovered in animals are not present in plants or found with a similar form. PCD in plants is developmentally controlled (by endogenous factors) to function in organ development and differentiations as well as environmentally induced (by exogenous stimuli) to help the plant in surviving under stress conditions. Here, we present a review of the role of PCD in plant development and explore different examples of stress-induced PCD as well as highlight the main differences between the plant and animal PCD.
