Description

Michael Mudgett and co-authors untangle how two plant genes steer the hormone flows that let a plant start to flower. Their 2025 study uses Arabidopsis, a small plant that serves as a lab standard. A plant that lacks one gene, called PID, never starts flowers on its stems, and faults in a gene family called NPY give the same blank look.

The team found that boosting the gene NPY1 fully masks the loss of PID, which places NPY1 downstream of it. The boost also switches on tags on the PIN proteins, which move the hormone, at fresh sites that differ from the known ones. Those tags seem to hold the PIN proteins back. A tail part of NPY1 must itself be tagged for the rescue to work.
