I'm thrilled that our recent paper on ultraviolet-absorbing floral patterns in sunflowers got a write up at Botany One! Read about it at Not For Your Eyes.*
* One quick note, what is reported as the "intensity of the pattern" was actually the proportional size of the UV bullseye (how much of the total floral surface it covers), which is controlled by a different part of the genome than the absolute size of the bullseye (its diameter). So, a small flowerhead can be 90% UV absorptive but still have a smaller diameter bullseye than a huge flowerhead that is 50% UV absorbing pigment.
