Tiny colour changes in wild snapdragons may decide which genes survive
Researchers have discovered that seven specific genes work together to fine-tune the color patterns of wild snapdragons in the Pyrenees. These subtle color variations are critical for attracting pollinators, directly impacting the survival of the plant's genes.
Why it matters
Understanding the genetic basis of plant evolution and pollinator interaction provides insights into biodiversity and the survival mechanisms of species in changing environments.
The art of seduction is not exclusive to humans. Animals do it, and so do plants. In the floral world, attraction is a matter of survival. Certain plants paint themselves in colours calibrated so precisely that bees can read them like landing signals, even when human eyes barely detect the difference!A new study published in the journal Science Advances explains how in the Pyrenees, wild snapdragons have turned color scientists of sorts. In the relentless pursuit of attracting bees, these flowers fine-tune their colors. These flowers are extremely careful while calibrating their colors, because even a slight change means the difference between life and death for a gene.The subtle art of seduction Researchers at the John Innes Centre, led by Professor Enrico Coen, spent years analyzing how snapdragons fine-tune their shades to win the attention of pollinators.
