Volatiles derived from carotenoids are released from a diversity of algae taxa and contribute to aquatic odors.  Here, we will present our latest findings about the biosynthesis in macro-algae and their biological activities.  It is well established that C13-apocarotenoids are among the most potent flavor compounds, however little is known about their biological behavior.  Recent studies indicate that some carotenoid derived breakdown products exhibit unknown functions.  This presentation will explore that C13-apocarotenoids or their metabolites exhibit new functions in relation to growth.  We observed first evidence of growth regulating effects of various C13-apocarotenoids with two species, namely Enteromorpha compressa L. Ness and Lemna pausicostata L..  C13-apocarotenoid treated and non-treated samples differ in their growth characteristics and can be distinguished based on non-targeted analysis of their metabolome.
