Ph sensing mechanism
WebSep 26, 2024 · In plants, the alteration in the pH of extracellular space serves as a cue to regulate a myriad of physiological activities, including ion transport, growth, and defense (Tsai and Schmidt, 2024). Although it is known that the alkalization or acidification of apoplast is involved in cellular processes such as auxin-mediated cell elongation and … WebApr 15, 2010 · In infected cells, loss of the pH 7.2 signal through acidification of host-cell cytosol prevented complex degradation and effector translocation. Thus, intravacuolar Salmonella senses host cytosolic pH, resulting in the degradation of regulatory complex proteins and effector translocation.
