Hechtian Strands Transmit Cell Wall Integrity Signals in Plant Cells

Plants, 2020
Hechtian strands are thread-like structures in plasmolyzed plant cells that connect the cell wall to the plasma membrane. Although these strands were first observed more than 100 years ago, their physiological roles are largely unknown. Here, we used intracellular laser microdissection to examine the effects of disrupting Hechtian strands on ...

Bacterial Cell Wall Quality Control during Environmental Stress

mBio, 2020
Single-celled organisms must adapt their physiology to persist and propagate across a wide range of environmental conditions. The growth and division of bacterial cells depend on continuous synthesis of an essential extracellular barrier: the ...

Cell Wall-linked Cryptococcal Phospholipase B1 Is a Source of Secreted Enzyme and a Determinant of Cell Wall Integrity [PDF]

Journal of Biological Chemistry, 2007
Phospholipase B (Plb1) is secreted by pathogenic fungi and is a proven virulence determinant in Cryptococcus neoformans. Cell-associated Plb1 is presumptively involved in fungal membrane biogenesis and remodelling. We have also identified it in cryptococcal cell walls.

Plant cell wall integrity maintenance in model plants and crop species-relevant cell wall components and underlying guiding principles

Cellular and Molecular Life Sciences, 2019
The walls surrounding the cells of all land-based plants provide mechanical support essential for growth and development as well as protection from adverse environmental conditions like biotic and abiotic stress.

Analysis of the cell wall integrity pathway of Ashbya gossypii

Microbiological Research, 2013
Fungal cells are exposed to rapidly changing environmental conditions, in particular with regard to the osmotic potential. This requires constant remodeling of the cell wall and, therefore, the cell wall integrity (CWI) MAP-kinase pathway plays a major role in shaping the fungal cell wall to protect from adverse external stresses.

Cdc48 and cofactors Npl4-Ufd1 are important for G1 progression during heat stress by maintaining cell wall integrity in Saccharomyces cerevisiae. [PDF]

PLoS ONE, 2011
The ubiquitin-selective chaperone Cdc48, a member of the AAA (ATPase Associated with various cellular Activities) ATPase superfamily, is involved in many processes, including endoplasmic reticulum-associated degradation (ERAD), ubiquitin- and proteasome ...

Interplay of the RNA Exosome Complex and RNA-Binding Protein Ssd1 in Maintaining Cell Wall Stability in Yeast

Microbiology Spectrum, 2021
Yeast cell wall stability is important for cell division and survival under stress conditions. The expression of cell-wall-related proteins is regulated by several pathways involving RNA-binding proteins and RNases.

Comprehensive phenotypic analysis of multiple gene deletions of α-glucan synthase and Crh-transglycosylase gene families in Aspergillus niger highlighting the versatility of the fungal cell wall

The Cell Surface
Multiple paralogs are found in the fungal genomes for several genes that encode proteins involved in cell wall biosynthesis. The genome of A. niger contains five genes encoding putative α-1,3-glucan synthases (AgsA-E) and seven genes encoding putative ...

The genetic interaction network of CCW12, a Saccharomyces cerevisiae gene required for cell wall integrity during budding and formation of mating projections

BMC Genomics, 2011
Background Mannoproteins construct the outer cover of the fungal cell wall. The covalently linked cell wall protein Ccw12p is an abundant mannoprotein.
