Gene regulatory network analysis of silver birch reveals the ancestral state of secondary cell wall biosynthesis in core eudicots

open access: yesNew Phytologist, Volume 246, Issue 5, Page 2059-2074, June 2025.
Summary The compact genome and lack of recent whole‐genome multiplication (WGM) events make the boreal pioneer tree silver birch (Betula pendula) a promising model for primary and secondary cell wall (PCW and SCW) regulation in forest trees. Here, we constructed regulatory networks through combined co‐expression and promoter motif analysis and carried ...

The developmental basis of floral nectary diversity and evolution

open access: yesNew Phytologist, Volume 246, Issue 6, Page 2462-2477, June 2025.
Summary Nectar is a central bridge between angiosperms and animal mutualists. It is produced by specialized structures termed nectaries, which can be found on different plant organs. Consumption of floral nectar by pollinators and the subsequent transfer of pollen contribute to the reproductive success of both angiosperms and their pollinators.
