Light has long been known to regulate plant growth. New research from Osaka Metropolitan University has discovered a new mechanism behind this regulation. A team led by Professor Kouichi Soga of the Graduate School of Science used a unique method to measure adhesion between the epidermal (the outermost layer) and inner tissues in young pea stems. They found that those grown in light exhibit enhanced adhesion. The research is published in Physiologia Plantarum.
