A new gene called FBP2 in petunia is important for flower development. When this gene is turned off, petals, stamens, and carpels change into sepal-like parts, and the flower's center loses its shape. FBP2 works together with another gene called FBP5. By studying FBP2, scientists found that it plays a similar role to a gene called SEP3 in Arabidopsis, which helps control how flowers grow. This shows that FBP2 is part of a group of genes that are crucial for making sure flowers develop correctly.
