[Abstract] Chromatin immunoprecipitation followed by sequencing (ChIP-seq) is a routine procedure in the lab; however, epigenome-wide quantitative comparison among independent ChIP-seq experiments remains a challenge. Here, we contribute an experimental protocol combined with a computational workflow allowing quantitative and comparative assessment of ...

[Abstract] High-throughput screening of a DNA library expressed in a bacterial population for identifying potentially rare members displaying a property of interest is a crucial step for success in many experiments such as directed evolution of proteins and synthetic circuits and deep mutational scanning to identify gain- or loss-of-function mutants.

Extraction and 16S rRNA Sequence Analysis of Microbiomes Associated with Rice Roots
[Abstract] Plant roots associate with a wide diversity of bacteria and archaea across the root-soil spectrum. The rhizosphere microbiota, the communities of microbes in the soil adjacent to the root, can contain up to 10 billion bacterial cells per gram of soil (Raynaud and Nunan, 2014) and can play important roles for the fitness of the host plant. Subsets ...
Single-step Precision Genome Editing in Yeast Using CRISPR-Cas9
[Abstract] Genome modification in budding yeast has been extremely successful largely due to its highly efficient homology-directed DNA repair machinery. Several methods for modifying the yeast genome have previously been described, many of them involving at least two-steps: insertion of a selectable marker and substitution of that marker for the intended ...
