Seminar Dr. Matyáš Fendrych
About the roles and mechanisms of rapid auxin responses in plant morphogenesis - Tuesday 28th May, 2024 9:30 am
The presentation of Matyáš Fendrych will revolve around the gravitropism of plant roots, and the role that auxin plays in this fascinating phenomenon. He will first summarize the currently recognized auxin signaling pathways. Then he will focus on the mechanisms and roles of the AFB1-dependent rapid auxin responses that steer gravitropism in Arabidopsis thaliana roots. The live-cell imaging methods developed to analyze the dynamic behavior of growing Arabidopsis roots, and present results on AFB1-dependent calcium ion spiking and changes in apoplastic pH and its importance for root gravitropism will be introduced. Further, his presentation will focus on the interplay of the rapid auxin response with the ‘classical’ TIR1 dependent transcriptional response, and he will argue that we do not understand how auxin controls cellular elongation in roots. Efforts to generate a new generation of apoplastic pH genetically encoded sensors will be presented. Finally, he will introduce the questions he wants to address in the near future.
