Assessment of Soil Microbial Communities in Carotenoid-Biofortified Rice Ecosystem

The Biogeography of Microbial Communities and Ecosystem Processes: Implications for Soil and Ecosystem Models

We are entering a period of rapid and pronounced environmental change. Understanding how this change will in! uence soil communities is essential for accurate prediction of future climate, biogeochemical cycles, and human well-being. Such reliable prediction is the fundamental test of scienti" c understanding (i.e. can we use knowledge of underlying mechanisms to predict accurately how phenomen...

Preliminary assessment of microbial-based soil additives

Molecular biomass and MetaTaxogenomic assessment of soil microbial communities as influenced by soil DNA extraction procedure

Three soil DNA extraction procedures (homemade protocols and commercial kit) varying in their practicability were applied to contrasting soils to evaluate their efficiency in recovering: (i) soil DNA and (ii) bacterial diversity estimated by 16S rDNA pyrosequencing. Significant differences in DNA yield were systematically observed between tested procedures. For certain soils, 10 times more DNA ...

Ecological Resilience of Soil Microbial Communities

Impact of fumigants on soil microbial communities.

Agricultural soils are typically fumigated to provide effective control of nematodes, soilborne pathogens, and weeds in preparation for planting of high-value cash crops. The ability of soil microbial communities to recover after treatment with fumigants was examined using culture-dependent (Biolog) and culture-independent (phospholipid fatty acid [PLFA] analysis and denaturing gradient gel ele...
