What to know about Supergene solves evolutionary puzzle of mirror-image flowers

An international research team led by the University of Potsdam has identified a 'supergene' that controls the mirror-image asymmetry of South African butterfly lilies. The study, published in Science, explains how this genetic mechanism ensures efficient cross-pollination by coordinating the orientation of styles and stamens relative to gravity.

What happened

Supergene solves evolutionary puzzle of mirror-image flowers Swati Mestri Scientific Editor Robert Egan Senior Editor The left-right asymmetry of South African butterfly lilies (genus Wachendorfia) has been regarded as a classic evolutionary puzzle for more…

Why it matters

Due to the mirror-image arrangement of the floral parts, the plants achieve efficient cross-pollination.

Common ground

The molecular basis of this arrangement has now been uncovered by an international team led by the University of Potsdam.
