The mechanism by which the plant hormone cytokinin controls cell division has been discovered - a breakthrough that significantly improves our understanding of how plants grow. Cell division is ...

Legume root nodules originate from differentiated cortical cells that reenter the cell cycle and form organ primordia. We show that perception of the phytohormone cytokinin is a key element in this ...
