Dominant trees affect microbial community composition and activity in post-mining afforested soils

Contribution of trees to the conservation of biodiversity and ecosystem services in agricultural landscapes

“…Furthermore, ectomycorrhizal biomass, as well as that of gram positive and negative bacteria, was found to be greater in the soils surrounding A. nepalensis. These findings are consistent with past studies showing the same trend of increased fungal and bacterial biomass in soils surrounding Alder trees of various species (Selmants et al 2005;Prescott and Grayston 2013;Šnajdr et al 2013).…”

Salt tolerant SUV3 overexpressing transgenic rice plants conserve physicochemical properties and microbial communities of rhizosphere

“…Further, the activity of phosphatase, nitrate reductase and urease in the rhizosphere of Bt cotton was enhanced over non-Bt cotton, however this difference was not significant (Devare et al, 2004). A similar trend of stimulation activity of urease, phosphatase, invertase and cellulase enzymes by the addition of Bt cotton tissues in soil was also reported (Snajdr et al, 2013). In the present study, the soil enzymatic activity of rhizospheric bacteria of transgenic and WT plants were performed in triplicate.…”

“…The analysis of soil enzymatic activity is one of the microbiological indicators of soil quality (Winding et al, 2005) and its quantitative determination as a function of microbial population provides responsive information about the changes taking place in the soil environment (Trasar-Capeda et al, 2000;Mina et al, 2011;Snajdr et al, 2013). There are several reports on cultivation transgenic plants and their influence on soil ecosystem (Flores et al, 2005;Griffiths et al, 2005Griffiths et al, , 2006Icoz et al, 2008;Sahoo and Tuteja, 2013).…”

Tree species select diverse soil fungal communities expressing different sets of lignocellulolytic enzyme-encoding genes

“…Forest soil fungal communities and their associated functions can be affected by several environmental variables including climatic factors, edaphic parameters, stand age and tree species composition (Trap et al, 2011;Snajdr et al, 2013;Tedersoo et al, 2014). For a given soil and climate, tree species and therefore the quality of litter they produce represent the overriding factor influencing soil fungal community composition and controlling SOM decomposition rate ( Snajdr et al, 2013).…”
