Cell wall integrity maintenance in plants
The plant cell wall is involved in different biological processes like cell morphogenesis and response to biotic/abiotic stress. Functional integrity of the wall is apparently being maintained during these processes by changing structure/composition and coordinating cell wall with cellular metabolism. In S.cerevisiae a well-characterized mechanism exists that is maintaining functional integrity...
متن کاملRegulation of cell wall biogenesis in Saccharomyces cerevisiae: the cell wall integrity signaling pathway.
The yeast cell wall is a strong, but elastic, structure that is essential not only for the maintenance of cell shape and integrity, but also for progression through the cell cycle. During growth and morphogenesis, and in response to environmental challenges, the cell wall is remodeled in a highly regulated and polarized manner, a process that is principally under the control of the cell wall in...
متن کاملAspergillus fumigatus RasA regulates asexual development and cell wall integrity.
The Ras family of proteins is a large group of monomeric GTPases. Members of the fungal Ras family act as molecular switches that transduce signals from the outside of the cell to signaling cascades inside the cell. A. fumigatus RasA is 94% identical to the essential RasA gene of Aspergillus nidulans and is the Ras family member sharing the highest identity to Ras homologs studied in many other...
متن کاملCell wall integrity signaling and innate immunity in plants
All plant pathogens and parasites have had to develop strategies to overcome cell walls in order to access the host's cytoplasm. As a mechanically strong, multi-layered composite exoskeleton, the cell wall not only enables plants to grow tall but also protects them from such attacks. Many plant pathogens employ an arsenal of cell wall degrading enzymes, and it has long been thought that the det...
متن کاملPutative cell wall integrity sensor proteins in Aspergillus nidulans
The cell wall integrity (CWI) signal transduction pathway, which has been well-studied in the yeast Saccharomyces cerevisiae, plays an important role in the regulation of cell wall biogenesis. Recently, we characterized the CWI stress sensor orthologs WscA and WscB in the filamentous fungus Aspergillus nidulans. Disruption of the wscA and wscB genes causes a change in the transcriptional levels...
