摘要: Herpesviruses have relatively large DNA genomes of more than 150 kb that are difficult to clone and sequence. Bacterial artificial chromosome (BAC) cloning herpesvirus is a powerful technique greatly facilitates whole viral genome sequencing as well functional characterization reconstituted viruses. We describe recently invented technologies for rapid BAC using CRISPR/Cas9-mediated homology-directed repair. focus on recent techniques Epstein-Barr virus (EBV) discuss the possible advantages strategy comparatively with precedent EBV-BAC strategies. also design decisions this technology pitfalls points be improved in future. The obtained clones subjected long-read analysis determine complete EBV sequence including repetitive regions. Rapid determination various strains will contribute understanding their global geographical distribution. This can used disease-associated test hypothesis they special features distinguish them from infect asymptomatically.
