[2018 Fall Life Sciences & IBB  Seminar]

▶Subject: Crop improvement by gene editing: challenges and solutions

 ▶Speaker: Yunde Zhao (University of California San Diego)

▶Date: 4:30PM/Nov. 2(Fri.)/ 2018

▶Place: Auditorium(1F), Postech Biotech Center

CRISPR gene editing technology enables precise editing of DNA sequences in vivo and it has been widely used in modifying genes in many organisms including plants. Editing genes in plants has unique challenges. One of the most important aspects of gene editing in plants is the removal of the CRISPR/Constructs once the intended gene editing is completed. Removal of the CRISPR construct is likely a prerequisite for regulatory approval of commercial applications of any edited crops. The existence of the CRISPR constructs prevents us from accurately determining heredity patterns and eliminating off target effects. The transgenes can be segregated out if the plants are propagated sexually, but genetic segregation and genotyping are time consuming and labor- intensive.  In this presentation, I will present several strategies that can efficiently, quickly, and reliably generate edited, but transgene free plants. Our strategy enables us to generate knockout rice plants lacking any transgenes in just a single generation.
