Mystery of Mirror-Image Flowers Solved by Scientists

Topic: Biology

A team of international researchers led by the University of Potsdam has discovered a 'supergene' that explains how some flowers develop mirror-image arrangements. This supergene determines whether plants grow styles and stamens bent to the left or right, allowing for efficient cross-pollination.

The left-right asymmetry of South African butterfly lilies (genus Wachendorfia) has been a puzzle for over a century. These plants have mirror-image arrangements of their floral parts, which helps them get pollinated efficiently.

A team of scientists from the University of Potsdam, the University of Cape Town, and Wageningen University worked together to solve this mystery. They found that a 'supergene' is responsible for determining whether the plants grow styles and stamens bent to the left or right. This supergene contains two key factors that control the orientation of these parts.

The researchers used plants from the species Wachendorfia thyrsiflora, which are grown in the Botanical Garden of the University of Potsdam. They conducted microscopic and developmental analyses on these plants to understand how the supergene works. The team's findings show that gravity plays a crucial role in determining the orientation of the styles and stamens.

The study is a result of a long-standing collaboration between researchers from different institutions. The combination of fieldwork, laboratory experiments, and theoretical modeling helped solve the puzzle of mirror-image flowers.
