On the left, a young Arabidopsis plant is shown, with one of the root tips indicated by the yellow line. The yellow box shows a virtual section through a three-dimensional reconstruction of the ...

This peptide diffuses through the root tip. Cells at the root apical meristem, which divide to form a new root cap, have a receptor protein, called HSL2, which perceives the signal peptide IDL1.

Researchers from the University of Freiburg have identified the HAN molecule as an important regulator that controls plant ...

From an enhancer trap screen for genes expressed in Arabidopsis embryos, we identified a gene expressed from the octant stage onward in the boundary between the two presumptive cotyledons and in a ...
