Researchers identify genetic mechanism that controls petal color in lotus

Lotus (Nelumbo) is a basal eudicot with agricultural and horticultural value. It is a worldwide aquatic ornamental belonging to the Nelmbonaceae family with only two species, N. lutea with yellow flowers and N. nucifera with red or white flowers. Although it is the most important trait in ornamental lotus, the genetic mechanism underlying the flower color difference in Nelumbo has not been fully characterized.
