Responses of soil bacterial and fungal communities to extreme desiccation and rewetting (2013, background): “As a whole, the bacterial community appears to tolerate the rapid upshock in water potential (influx of water), which is known to cause lysis (plasmoptysis) in many bacterial cells that have adjusted to low water potential conditions (Kieft et al., 1987; Halverson et al., 2000).”
Water pulses and biogeochemical cycles in arid and semiarid ecosystems (2004, background): “Rapid change in soil water potential associated with rewetting may cause microbes to undergo osmotic shock, including microbial cell lysis (Bottner 1985; Van Gestel et al. 1993) or a release of intracellular solutes (Halverson et al. 2000).”
Linking microbial community composition to function in a tropical soil (2000, background): “Gram-positive bacteria have sometimes been considered to be stress tolerators that grow slowly and tend to be able to metabolize complex carbon substrates more readily than Gram-negative bacteria (Paul and Clark, 1989; Halverson et al., 2000 ).”
Influence of Drying–Rewetting Frequency on Soil Bacterial Community Structure (2002, background): “total soil water potential associated with a rewetting event will cause microbes to undergo osmotic shock, possibly inducing microbial cell lysis and a release of intracellular solutes [21, 25, 30].”
Endophytic bacteria (Sphingomonas sp. LK11) and gibberellin can improve Solanum lycopersicum growth and oxidative stress under salinity (2015, background): “Though bacterial cells have energy-dependent active transport system to maintain the influx of such ions, however, during such continued exposure the radical/ion scavenging enzymes can help in arresting the adverse effects (Halverson et al. 2000; Ali et al. 2014).”
Microbial community response to varying magnitudes of desiccation in soil: A test of the osmolyte accumulation hypothesis (2013, background): “The response of soil microorganisms to low water potential has been studied by exposing soil isolates to salt induced hyperosmotic stress and through desiccation on a simulated soil matrix (Killham and Firestone, 1984, 1984b; Schimel et al., 1989; Roberson and Firestone, 1992; Halverson et al., 2000”
Microbial stress-response physiology and its implications for ecosystem function. (2007, unknown): “For example, Kieft et al. (1987) showed that as much as 50 % of the microbial biomass could be released on upon rewetting, although probably little of this is from cell death (Halverson et al. 2000).”
