Plant steroids offer new paradigm for how hormones work

Steroids bulk up plants just as they do human athletes, but the playbook of molecular signals that tell the genes to boost growth and development in plant cells is far more complicated than in human and animal cells. A new study by plant biologists at the Carnegie Institution used an emerging molecular approach called proteomics to identify key links in the steroid signaling chain. Understanding how these plant hormones activate genes could lead not only to enhanced harvests but also to new insights into how steroids regulate growth in both plant and animal cells.
