How does a plant determine the angle at which a new lateral root should grow? A recent study by Farkas et al. reveals that the answer may depend not only on how plants perceive gravity, but when they perceive it. Lateral roots initially emerge almost perpendicular to the primary root before developing…

In vitro regeneration is a common process for clonal propagation and genetic engineering in plants. However, the regulation of the process has remained underexplored. Understanding the regulatory mechanisms can help design strategies to improve efficiency. In our recent study published in The Plant Cell…

Root growth and branching is strongly tuned to environmental conditions including soil compaction, nutrient availability, and the presence of water, with auxin having a major role in regulating root architecture. Here, Roy et al. have demonstrated how auxin contributes to a suppression of root branching…

For hundreds of years, we have propagated plants clonally by grafting, i.e. the union of a scion and a rootstock to form a new plant. To be successful, a graft junction must heal: tissues must attach, and vascular bundles reconnect, in a process known to involve auxin. Here, Serivichyasw at et al. investigate…

Auxin is a pleiotropic plant hormone with diverse functions, many of which are mediated through transcriptional reprograming. However, some auxin responses occur extremely rapidly, ruling out changes in transcription as a mechanism. In 2022, one of the components of an auxin receptor, F-box protein TIR1/AFB,…
