Auxin fluxes through plasmodesmata

Characterising the processes that control auxin dynamics is essential to understanding how auxin regulates plant development. Over recent years, several studies have investigated auxin diffusion through plasmodesmata, characterising this cell-to-cell diffusion and demonstrating that it affects auxin distributions. Furthermore, studies have shown that plasmodesmatal auxin diffusion affects developmental processes, including phototropism, lateral root emergence and leaf hyponasty. This short Tansley Insight review describes how these studies have contributed to our understanding of auxin dynamics and discusses potential future directions in this area.

Automated summary

The process of characterising how auxin dynamics are controlled is crucial for understanding how auxin plays a role in regulating plant development. Recent studies have shown that auxin diffusion through plasmodesmata influences auxin distributions and subsequently impacts developmental processes such as phototropism, lateral root emergence, and leaf hyponasty. This review highlights how these studies have contributed to our comprehension of auxin dynamics and explores potential future research directions in this field.
