Physcomitrium patens SMXL homologs are PpMAX2-dependent negative regulators of growth

A. Guillory, M. Lopez-Obando, K. Bouchenine, L. Lambret, P. Le Bris, A. Lecureuil, J.-P. Pillot, V. Steinmetz, F.-D. Boyer, C. Rameau, A. de Saint Germain, S. Bonhomme

This study investigates the function of SMXL genes in the moss Physcomitrium patens, showing they are negative regulators of growth via the MAX2-dependent KL signaling pathway and can partially replace SMXL4/5 function.
