内容简介：

CRISPR gene editing technologies have revolutionized biology and crop improvement. In this presentation, I will first describe the remaining challenges of gene editing technologies in plants followed by presenting our effort in improving several aspects of CRISPR gene editing technology. I will focus on two main areas of CRISPR technology: Homology-directed DNA repair (HDR) and transgene-free genome editing. HDR has been regarded as the Holy Grail of genome editing in plants and offers unprecedented applications in agriculture.  We have developed new strategies that enabled HDR-based gene replacements in plants. Transgene-free is likely a prerequisite to gain regulatory approval of edited crops. My group has pioneered several strategies that accelerate the isolation of transgene-free, gene-edited plants. Our latest technology allows the isolation of edited, transgene-free plants within a single generation, greatly accelerating crop breeding. I will use editing auxin pathways as an example to demonstrate the power of our new technologies in both basic and applied plant biology.
