Release of volatile aldehydes by the brown algal kelp Laminaria digitata in response to both biotic and abiotic stress

Chembiochem. 2009 Apr 17;10(6):977-82. doi: 10.1002/cbic.200900004.

Abstract

With a little kelp from my friends: In response to biotic and abiotic stress, the brown algal kelp Laminaria digitata releases volatile fatty acid aldehydes under laboratory conditions and in its natural environment (red). In response to 4-HHE treatment, L. digitata releases (13S)-HOTrE (green). These results support the hypothesis that these compounds may mediate kelp responses to stress.
