PagMIR166c targets PagECH2 to regulate cambial differentiation into secondary xylem, cell expansion, and lignin deposition via different auxin signaling pathways in poplar stems

open access: yesNew Phytologist, Volume 248, Issue 1, Page 321-338, October 2025.
Summary Secondary xylem, a key trait of trees, is the main source of tree biomass. MicroRNAs (miRNAs) play important regulatory roles in the secondary xylem formation; however, the underlying regulatory mechanisms are far from being completely elucidated.

Tomato flowering depends on overlapping functions of AP1/FUL‐like genes in reproductive meristem specification

open access: yesNew Phytologist, Volume 248, Issue 2, Page 1002-1020, October 2025.
Summary AP1/FUL‐clade transcription factors (TFs) are essential for the initiation and regulation of flowering and have clearly separated functions in Arabidopsis. However, how these functions have diverged across eudicots remains unclear. Here, we performed a detailed analysis to unravel the distinct and overlapping functions of the tomato AP1 ...
