Streamlined generation of plant virus infectious clones using the pLX mini binary vectors.

Recent metagenomic surveys have provided unprecedented amounts of data that have revolutionized our understanding of virus evolution and diversity. Infectious clones are powerful tools to aid the biological characterization of viruses. We recently described the pLX vectors, a set of mini binary T-DNA vectors (∼3 kb) that includes strong bacterial terminators and a minimal replicon from the broad-host-range plasmid pBBR1, which replicate autonomously in both Escherichia coli and Agrobacterium.
