“…Previous studies demonstrated that petals are mainly responsible for volatile production and emission in the flowers of many plant species (Dobson, 1994;Dudareva et al, 2000b). In our study, LiBSMT was predominantly expressed in the petals of flowers, from which volatile compounds are typically emitted (Kong et al, 2012).…”

ABSTRACT. In lily flowers, the volatile ester methyl benzoate is one of the major and abundant floral scent compounds; however, knowledge regarding the biosynthesis of methyl benzoate remains unknown for Lilium. In this study, we isolated a benzoic acid/salicylic acid carboxyl methyltransferase (BSMT) gene, LiBSMT, from petals of Lilium 'Yelloween'. The gene has an open reading frame of 1083 base pairs (bp) and encodes a protein of 41.05 kDa. Sequence alignment and phylogenetic analyses of LiBSMT revealed 40-50% similarity with other known benzenoid carboxyl methyltransferases in other plant species, and revealed homology to BSMT of Oryza sativa.

“…Flowering plants use diverse, multifunctional biosynthetic pathways to produce a broad spectrum of BVOCs that collectively confer characteristic fragrances to flowers 24 . The results of this study highlight the mostly neglected role of phyllospheric microbiota in these emissions.…”

The emission of floral terpenes plays a key role in pollination in many plant species. We hypothesized that the floral phyllospheric microbiota could significantly influence these floral terpene emissions because microorganisms also produce and emit terpenes. We tested this hypothesis by analyzing the effect of removing the microbiota from flowers. We fumigated Sambucus nigra L. plants, including their flowers, with a combination of three broad-spectrum antibiotics and measured the floral emissions and tissular concentrations in both antibiotic-fumigated and non-fumigated plants. Floral terpene emissions decreased by ca. two thirds after fumigation. The concentration of terpenes in floral tissues did not decrease, and floral respiration rates did not change, indicating an absence of damage to the floral tissues. The suppression of the phyllospheric microbial communities also changed the composition and proportion of terpenes in the volatile blend. One week after fumigation, the flowers were not emitting β-ocimene, linalool, epoxylinalool, and linalool oxide. These results show a key role of the floral phyllospheric microbiota in the quantity and quality of floral terpene emissions and therefore a possible key role in pollination.

“…However, free linalool was hardly detectable. Linalool is frequently encountered in floral scents, where it is formed by linalool synthase (Dudareva et al, 1996(Dudareva et al, , 1999. In petals of grape, linalool appears to be efficiently glucosylated and metabolized to other metabolites, such as linalool oxides (Raguso and Pichersky, 1999).…”
