Generation of mutants of nuclear-encoded plastid proteins using CRISPR/Cas9 in the diatom Phaeodactylum tricornutum

International audienceGenome modifications in microalgae are becoming a widespread and mandatory tool for research in both fundamental and applied biology. Among genome editing methods in these photosynthetic organisms, CRISPR/Cas9 offers a specific, powerful and efficient tool for genome engineering by inducing mutations in targeted regions of the genome. Here we described a protocol that allows the generation of knockout mutants by CRISPR/Cas9 in the diatom Phaeodactylum tricornutum using biolistic transformation
