steroid-hormone-signaling-in-plants-untangledPlants tend to “pump” up like major league baseball players do on steroids when they are given extra shots of brassinolide, the plant steroid. Researchers at the Salk Institute for Biological Studies while tracing signal of brassinolide deep into the cell’s nucleus unraveled how the growth-boosting hormone performs this job at the molecular level.

The Salk researchers, led by Joanne Chory, a professor in the Plant Molecular and Cellular Biology Laboratory and a Howard Hughes Medical Institute investigator, published their findings in the journal Nature.

Chory remarked that this study clarifies what happens in the downstream in the nucleus when brassinolide signals a plant cell to grow.
