The growth of #plant leaves is highly dynamic and should be coordinated, but how is #leaf flatness preserved? @roederlab.bsky.social &co show that global coordination of growth across the leaf blade is required to maintain flatness in #Arabidopsis @plosbiology.org 🧪 buff.ly/QUMxOcF
While WT leaves progressively flatten, jaw-D leaves curve at the base. Gaussian curvature displayed as heatmaps on wildtype (left) and jaw-D mutant (right) leaf meshes. Gaussian curvature represents both the magnitude and direction of curvature such that values further from zero represent greater curvature. Orange arrows indicate high positive curvature that develops at the base of jaw-D leaves. Black scale bars = 200 µm.

ONLINE COVER
Maximum-intensity projection of a confocal image of epidermal cells from the Thale cress roots, where four colors stain different cell parts. 

Goldy et al. demonstrate that the protein actin allows cells to override standard division rules by stabilizing the orientation of spindles, which segregate chromosomes during mitosis. This uncovers a previously under-appreciated role for actin cytoskeletons, providing new insight into how division orientation is controlled to ensure robust tissue architecture during plant growth.

Cour supérieure | McGill et Concordia ont en partie gain de cause contre Québec
La Cour supérieure donne en partie raison aux universités McGill et Concordia dans leur bataille contre le gouvernement Legault. La hausse des droits de scolarité imposée aux étudiants provenant des autres provinces canadiennes est jugée déraisonnable. Tout comme l’obligation imposée aux deux universités de franciser 80 % de ces étudiants et ceux de l’étranger sous peine de perdre leurs subventions.
