The exogenous application of the apocarotenoid retinaldehyde negatively regulates auxin-mediated root growth

Short-term inhibition of carotenoid biosynthesis increases retinal levels, which reduce auxin levels and signaling to suppress root growth.

The bHLH transcription factor MpHYPNOS regulates gemma dormancy in the liverwort Marchantia polymorpha

This study identifies MpHYPNOS as a key regulator of gemma dormancy in liverworts, showing it represses cell cycle genes and induces ABA biosynthesis through an ABA-independent pathway.

Autophagy promotes organelle clearance and organized cell separation of living root cap cells in Arabidopsis thaliana

The paper uses live-cell tracking to show autophagy facilitates organelle rearrangement and organized cell separation in Arabidopsis root cap cells during their functional transition.

Visualization of seasonal phosphorus re-translocation, and expression profile of phosphate transporters in a shortened annual cycle system of the deciduous poplar tree

The paper visualizes seasonal phosphorus re-translocation in poplar trees and analyzes phosphate transporter expression in a shortened annual cycle system.

Cytoskeleton dynamics control early events of lateral root initiation in Arabidopsis

This study shows that cytoskeleton dynamics, regulated by auxin signaling, are essential for asymmetric expansion and division of lateral root founder cells in Arabidopsis.

An evolutionarily conserved mechanism for production of secondary meristems in land plants

The paper identifies GCAM1 as an essential regulator of gemma cup development in Marchantia polymorpha, suggesting an ancient conserved mechanism for secondary meristem production in land plants.

The RopGEF KARAPPO is Essential for the Initiation of Vegetative Reproduction in Marchantia

This study identifies KARAPPO, a RopGEF, as essential for initiating vegetative reproduction in Marchantia by promoting gemma initial formation through Rop signaling.
