Research team reveals cellular and molecular basis of spur development in Impatiens uliginosa

As an important reproductive organ of angiosperms, flowers have a clear purpose and adaptive significance in their various characteristics. As a typical floral evolutionary feature, the floral spur is a tubular structure extending from the petal, which has undergone several independent evolutions in angiosperms (e.g., Impatiens, Aquilegia, Linaria, etc.).
