Genome Editing in Diatoms Using CRISPR-Cas to Induce Precise Bi-allelic Deletions
[Abstract]  Genome editing in diatoms has recently been established for the model species Phaeodactylum tricornutum and Thalassiosira pseudonana. The present protocol, although developed for T. pseudonana, can be modified to edit any diatom genome as we utilize the flexible, modular Golden Gate cloning system. The main steps include how to design a construct using Golden Gate cloning for targeting two sites, allowing a precise deletion to be introduced into the target gene. The ...

Markerless Gene Editing in the Hyperthermophilic Archaeon Thermococcus kodakarensis
[Abstract]  The advent of single cell genomics and the continued use of metagenomic profiling in diverse environments has exponentially increased the known diversity of life. The recovered and assembled genomes predict physiology, consortium interactions and gene function, but experimental validation of metabolisms and molecular pathways requires more directed approaches. Gene function–and the correlation between phenotype and genotype is most obviously studied with genetics, and it is therefore critical ...

Gene Dosage Experiments in Enterobacteriaceae Using Arabinose-regulated Promoters
[Abstract]  This protocol is used to assay the effect of protein over-expression on fitness of E. coli. It is based on a plasmid expression of a protein of interest from an arabinose-regulated pBAD promoter followed by the measurement of the intracellular protein abundance by Western blot along with the measurement of growth parameters of E. coli cell expressing this protein.
