Auxin biology: new approaches and surprising findings

Plants have evolved sophisticated mechanisms to control auxin homeostasis and signaling, making it challenging to study the roles of auxin in plant development. My group has developed several technologies that enable precise modifications of genes in plants. The technological advances provide unprecedented tools to study auxin biology. In this presentation, I will first describe the efficient gene targeting technology and in situ tagging genes with GFP using CRISPR-based homologous recombination. The technology avoids the pitfalls of transgenic approaches such as co-suppression and ectopic overexpression. Our gene editing technologies played a key role in elucidating the main auxin inactivation pathway. The technologies have led to new insights into several well characterized auxin genes. Finally, I will present the potential applications of our auxin research in crop improvement.
