Nucleic acid extraction NAE plays a vital role in molecular biology as the primary step for many downstream applications. Many modifications have been introduced to the original 1869 method. Modern processes are categoried into chemical or mechanical each with peculiarities that influence their use especially in point-of-care diagnostics POC-Dx
Despite their importance as a reservoir of biodiversity the factors shaping soil microbial communities and the extent by which these are impacted by cultivation are still poorly understood. Using 16S rRNA gene and ITS sequencing we characteried the soil microbiota of vineyards and of neighboring permanent grassland soils in the Italian province of Trentino and correlated their structure
