This volume explores a collection of methods that studies genome editing across a variety of bacteria, phages, and plants. Chapters in this book cover topics such as scarless DNA recombineering of phage in the lysogenic state; HEMSE; Dup-In and DIRex; recombineering in Staphylococcus aureus; and genome editing with Cas9 in lactobacilli. Written in the highly successful series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, is a valuable resource for any researchers interested in learning more about this developing field.
