Pbx Proteins in Cryptococcus neoformans Cell Wall Remodeling and Capsule Assembly [PDF]

Eukaryotic Cell, 2014
ABSTRACT The cryptococcal capsule is a critical virulence factor of an important pathogen, but little is known about how it is associated with the cell or released into the environment. Two mutants lacking PBX1 and PBX2 were found to shed reduced amounts of the capsule ...

Single-cell transcriptome sequencing (ScRNA-seq) uncovers the regulatory role of lodicule cells in rice floret opening (FO)

Communications Biology
Floret opening (FO) in rice (Oryza sativa L.) is triggered by lodicule swelling. However, the regulatory mechanisms underlying lodicule-mediated FO remain largely unclear.

Structural evolution of a fungal cell wall protein family for β-glucan-binding and cell separation

mBio
In fungi, the continuous biosynthesis and remodeling of the cell wall are crucial for growth, division, and development. A hallmark of fungal cell walls is their layered structure, which includes several carbohydrate polymers, such as β-glucans, and a ...

Nitrate Uptake Affects Cell Wall Synthesis and Modeling

Frontiers in Plant Science, 2017
Nowadays, the relationship(s) about N assimilation and cell wall remodeling in plants remains generally unclear. Enzymes involved in cell wall synthesis/modification, and nitrogen transporters play a critical role in plant growth, differentiation, and ...

Modulation of Peptidoglycan Synthesis by Recycled Cell Wall Tetrapeptides

, 2020
The bacterial cell wall is made of peptidoglycan (PG), a polymer that is essential for the maintenance of cell shape and survival. During growth, bacteria remodel their PG, releasing fragments that are predominantly reinternalized and recycled.

Intrusive growth of sclerenchyma fibers [PDF]

, 2010
Intrusive growth is a type of cell elongation when the rate of its longitudinal growth is higher than that of surrounding cells; therefore, these cells intrude between the neighboring cells penetrating the middle lamella.

MicroRNA-mediated regulation of cell wall dynamics and intercellular communication under stress

Frontiers in Plant Science
MicroRNAs (miRNAs) are short endogenous non-coding RNAs that regulate gene expression at the post-transcriptional level through mRNA cleavage or translational repression.

Uterine spiral artery remodeling involves endothelial apoptosis induced by extravillous trophoblasts through Fas/FasL interactions. [PDF]

, 2005
Objective— Invasion of uterine spiral arteries by extravillous trophoblasts in the first trimester of pregnancy results in loss of endothelial and musculoelastic layers.

The Dynamics of the Cell Wall Proteome of Developing Alfalfa Stems

Biology, 2019
In this study, the cell-wall-enriched subproteomes at three different heights of alfalfa stems were compared. Since these three heights correspond to different states in stem development, a view on the dynamics of the cell wall proteome during cell ...

Extracellular vesicles secreted by Saccharomyces cerevisiae are involved in cell wall remodelling [PDF]

Communications Biology, 2019
AbstractExtracellular vesicles (EVs) are membranous vesicles that are released by cells. In this study, the role of the Endosomal Sorting Complex Required for Transport (ESCRT) machinery in the biogenesis of yeast EVs was examined. Knockout of components of the ESCRT machinery altered the morphology and size of EVs as well as decreased the abundance of
