Jérôme Joubès and Didier Thoraval collaborated with the team of Reinhard Jetter (UBC, Vancouver, Canada) in a new article published in "Plant Cell and Environment" on the functional characterization of a member of the β-ketoacyl-CoA synthase family, namely KCS16, the key condensing enzyme involved in biosynthesis of C36 and C38 acyl-CoAs for cuticular wax formation in Arabidopsis leaf trichomes and pavement cells. These findings are a major step forward in our understanding of cuticular wax formation, as they provide detail on the functional diversification of a fairly big gene family, on the cell-type-specific and development-specific control of wax formation, and thus manifest the degree of genetic control over wax chemical diversity.
