The not-as-sweet smell of warming temperatures
Increasing temperature reduces production of scent compounds in two petunia varieties tested. Subsequent interference with the ability to attract pollinators is another way in which climate change could alter plant development and ecological relationships.

The rhythm of floral fragrance
An ordinary garden petunia, which releases its scent at night to attract pollinators such as months has been used to study the timing of fragrance. The LHY gene, which is associated with the circadian clock in many plants, was found to be active in the morning, regulating scent production through a suppressive effect. Scientists are now studying how pollinators respond to plants with and without altered LHY genes with a view to improving the pollination efficiency of crop species.
