Caption: Alfalfa roots secrete chemical signals into soil to attract and recruit bacteria. These bacteria live in a plant's roots and provide a natural fertilizer source. Pictured is an alfalfa root with root hairs that have attracted rhizobia soil bacteria, which are engineered to appear in green fluorescence for easier visualization.
