'Noisy' gene atlas to help explain how plants survive environmental change

25 January 2019

As parents of identical twins will tell you, they are never actually identical, even though they have the same genes. This is also true in the plant world. Now, new research by the 探花直播 of Cambridge is helping to explain why 鈥榯win鈥 plants, with identical genes, grown in identical environments continue to display unique characteristics all of their own.

Petals produce a 'blue halo' that helps bees find flowers

New study finds 鈥渕essy鈥 microscopic structures on petals of some flowers manipulate light to produce a blue colour effect that is easily seen by bee pollinators. Researchers say these petal grooves evolved independently multiple times across flowering plants, but produce the same result: a floral halo of blue-to-ultraviolet light.
