AI Article Synopsis

  • Auxin triggers a wide range of responses in plants, but understanding how this works is challenging due to its brief nuclear signaling pathway.
  • To decode the auxin response, it's crucial to examine factors like how auxin response components interact, the dynamics of these interactions, and how they relate to proteins and transcription regulation.
  • This review focuses on recent advancements in identifying and measuring these interactions while pointing out areas where more research is needed.

Article Abstract

How does auxin provoke such a diverse array of responses? This long-standing question is further complicated by a remarkably short nuclear auxin signalling pathway. To crack the auxin code, several potential sources of specificity need to be evaluated. These include: specificity of interactions among the core auxin response components, specificity resulting from higher order complex dynamics, and specificity in interactions with global factors controlling protein turnover and transcriptional repression. Here, we review recent progress towards characterizing and quantifying these interactions and highlight key gaps that remain.
