Plant editing gets easier with CRISPR loaded pollen

maisPollination is a natural way to deliver DNA into plant cells. So why not to use pollen as a vehicle for CRISPR machinery to start genome editing? HI Edit, as this approach is called, has been successfully tested by Syngenta in corn, Arabidopsis and wheat in the lab. Please see the paper just published in Nature Biotechnology by Timothy Kelliher et al., Jon Cohen’s piece in Science, and a quick guide to HI (haploid induction) from Current Biology. Leading wheat geneticist Cristobal Uauy of the John Innes Centre also showed high spirit, when asked for comment by email: “The possibility to genome edit any variety is revolutionary given that transformation is so difficult in many species. If I understand this correctly this would be a game changer as it would allow us to alter genes in elite cultivars.”
