Shapeshifting in the amphibious plant, Callirtriche palustris

Koga et al. identified a mechanism that produces heterophylly in aquatic plants grown either submerged in water or in air.  Plant Cell.  https://doi.org/10.1093/plcell/koab192 By Hiroyuki Koga, The University of Tokyo, 7-3-1, Hongo, Bunkyo-ku, Tokyo, 113-0033, Japan.

The secret to leaf forever: Mechanisms controlling simple leaf development (Nature Plants)

The final shape of a leaf is a consequence of differential growth at its margins. Simple (or lightly serrated) leaves result from limited growth in the margins, while compound leaves result from a constant initiation of leaflets. A recent work by Challa, Rath, and colleagues dissected the regulatory…

Sweeter than SWEET: A Single-Cell Leaf Vasculature Transcriptome Atlas

Kim et al. provide insight into leaf vascular cell types and new resources to build hypotheses and strategies regarding transport of ions, metabolites, and signals. Plant Cell http://bit.ly/2MKOR8M Ji-yun Kim and Wolf Frommer Background: Transport processes are critical for all multicellular…

Review: The mechanical feedback theory of leaf lamina formation ($) (Trends Plant Sci.)

The contribution of microtubule orientation to the direction of cell expansion is familiar to most; when microtubules wrap around the middle of a cell like a belt, the cell expands in the perpendicular direction to become longer. Recent studies have extended this idea and proposed that the mechanical…

Keeping a lid on shoot regeneration: SIZ1 suppresses wound-induced developmental reprogramming
