Description
Arthur K. Chan, Michael J. Scanlon, and Gladys F. A. Melo-de-Pinna trace how leaf sheaths fuse in a dayflower relative, Commelina erecta, in a 2026 plant anatomy study. Sheaths in this family close around the stem, unlike the mostly open sheaths of grasses. The team sectioned shoot tips and young leaves for microscopy and tested for activity of a KN1-related gene.
Anatomy showed the sheath margins first form apart, then fuse after contact, a pattern called postgenital fusion. No KN1 signal appeared at the fusing margins. Grasses build sheaths with KN1 involvement, so this family seems to use a different molecular route. The contrast sharpens how plant organs can reach similar forms by separate means.
