Implementing the CRISPR/Cas9 Technology in Hairy Roots Using Wood-Related Genes.

Eucalypts are the most planted hardwoods worldwide. The availability of the genome highlighted many genes awaiting functional characterization, lagging behind because of the lack of efficient genetic transformation protocols. In order to efficiently generate knock-out mutants to study the function of eucalypts genes, we implemented the powerful CRISPR/Cas9 gene editing technology with the hairy roots transformation system.
