SUMMARY:Investigating the Origin of Nanostructures on Flowers - Dr Chiara 
 Airoldi\, Department of Plant Sciences
DTSTART:20211104T130000Z

CONTACT:Kumari Billakurthi
DESCRIPTION:Part of Hibiscus trionum petals have a wrinkled cuticle that c
 reates a visual signal perceived by pollinators. \nThese wrinkles are orde
 red nanostructures capable of scattering light. They develop from the cuti
 cle on epidermal cells and maintain their orientation across several cells
 \, forming tissue-wide patterns. \nOur experiments demonstrate that they r
 esult from mechanical instabilities rather than from the guided deposition
  of material secreted by the cell. We have performed a detailed characteri
 zation of Hibiscus trionum petal development and the mechanical properties
  of its cuticle to understand how a buckling process produces these micros
 copic ordered structures.\n\nContact reception@plantsci.cam.ac.uk for a Zo
 om link prior to a talk if you are not on our mailing list. Due to having 
 to go online\, we are restricting the talks to University of Cambridge and
  alumni to keep them as informal as possible.
