Arabidopsis meristem map uncovers 18 cell clusters shaping stems and flowers

Researchers have produced the most detailed map yet of how stem cells in the growing tip of a plant begin their journey to form the many cell types that shape flowers and stems. They identified 18 distinct cell type clusters in the inflorescence meristem (the stem cell niche at the tip of the flowering shoot) that generates a plant's above-ground organs, such as stems and flowers.
