Researchers have identified 18 distinct cell type clusters in the inflorescence meristem that generate a plant's above-ground organs. The study provides new insights into how stem cells make the transition from an undifferentiated state to specialized cell types.
Researchers propose that internal physical stresses generated during growth limit lateral size, but a specific phyllotactic pattern may control growth. A study suggests the distribution of grain boundaries in this pattern might be determinant for controlling lateral growth.
Researchers created a three-dimensional simulation of plant growth, simulating cell division and auxin concentrations to reveal the molecular mechanism behind phyllotaxis. The model enhances biological experiments and promises accurate models for other organisms' development from primordial stem cells.
