Induction of cold active acid phosphomonoesterase activity at low temperature in psychrotrophic ectomycorrhizal Hebeloma spp.

https://doi.org/10.1017/S0953756298006753Get rights and content

Hebeloma strains of arctic and temperature origin, grown at 22° or 6°, were assayed for wall-bound and extracellular acid phosphomonoesterase (pNPPase) across a temperature range 2-37°. Only when grown at 6° was a cold active extracellular pNPPase induced in all the arctic strains and most of the temperature strains tested. Such enzymes are suggested to be a adaptation to low soil temperatures, and are discussed in the context of ectomycorrhizal access to soil PO4 monoesters at low temperature.

      Many microbes exhibit optimization of turnover rate relative to substrate binding, i.e. Kcat/Km, and increased thermolability, such as lower denaturing temperatures (Gerday et al. 1997). There is also evidence that different extracellular enzymes with lower thermal maxima are expressed when fungal cells are chilled (Tibbett et al. 1998, 1999), and that membrane composition is altered at low temperature (Kerekes & Nagy 1980; Hammonds & Smith 1986; Weinstein et al. 2000). However, such adaptations carry with them tradeoffs at higher temperatures.

      There is evidence from different studies (Taylor et al., 2000; Peter et al., 2001; Avis et al., 2008) that ECM fungal diversity and proteolytic capabilities are greater in the podzolic boreal soils with mor-type humus, where N mineralization is poor, than in the soils with mull-type humus of temperate forests. As also shown for organic N mobilization, extracellular phosphatases production can vary depending on the fungal species, and even on the strain (Meyselle et al., 1991; Cairney and Burke, 1996; Tibbett et al., 1998b, 1998c; Buée et al., 2005; Courty et al., 2005). The interactions between symbiotic fungi within ECM communities extend to larger fungal communities that include saprotrophic species, as reported by Lindahl et al. (1999) who demonstrated in a microcosm system the translocation of 32P between interacting mycelia of a wood-decomposing fungus and ECM fungi.
