TABLE OF CONTENTS
We describe a simple method, split-marker-mediated multiple-piece cloning (SMC), to rapidly assemble multiple DNA fragments into one construct in yeast. In this approach, a selectable marker is split into two non-functional, overlapping halves, of which one half is on the plasmid backbone. Homologous recombination reconstitutes the marker gene and assembles all DNA fragments in the desired order. This method allows rapid one-step fusion of various DNA fragments that contain ~30 base pair overlaps in yeast using raw PCR and/or restrict enzyme-digested products. We assembled seven DNA fragments into one contig in a single step by SMC in eight days.
