Photoperiodism (discovered in 1918) shows that flowering in plants is controlled by changes in day length. In the 1950s, BARC scientists discover phytochrome, a dual-form plant protein that determines when a plant will start, or put off, flowering. This serves as a core concept in plant physiology in labs all around the country today.
