Pathways that lead to floral scent volatiles. Volatile compounds are shown with a yellow background; enzymes that have been identified in the synthesis of volatile compounds in vegetative tissues are shown in black; enzymes identified in floral tissues are shown in red. Not all reactions or enzymes have been identified. A, Sesquiterpenes (top) are synthesized in the cytosol. Biosynthesis of monoterpene (bottom) occurs in the plastids, although the location of the reactions leading to further modifications (e.g. linalool oxide) is not yet clear. B, The location of synthesis of most phenolpropanoids/benzenoids is not yet known, but is likely to be the cytosol and possibly the peroxisomes. IEMT, SAMT, and BAMT are methyltransferases that use SAM (not shown) as the methyl donor. BEAT is an acetyltransferase that uses acetyl-CoA (not shown) as the acetyl donor.

Localization of expression of theIEMT gene in C. breweri flowers by RNA in situ hybridization. A, Cross-section of a petal from a 1-d-old flower. B, Cross-section of an anther in a mature flower bud. Samples were hybridized with an IEMT antisense probe. White dots visualized by dark-field microscopy indicate location of hybridization. This figure was obtained by Dr. Jihong Wang (University of Michigan, Ann Arbor).
