  abstract  = {2-Phenylethanol (2PE) and 3,5-dimethoxytoluene (DMT) are characteristic scent compounds in specific roses such as Rosa x hybrida cv. 'Yves Piaget'. We analyzed the endogenous concentrations and emission of 2PE and DMT during the unfurling process in different floral organs, as well as changes in transcript levels of the two key genes, PAR and OOMT2. The emission of both 2PE and DMT increased during floral development to reach peaks at the fully unfurled stage. The relative transcripts of PAR and OOMT2 also increased during floral development. Whereas the maximum for OOMT2 was found at the fully unfurled stage (stage 4), similar expression levels of PAR were detected at stage 4 and the senescence stage (stage 6). The results demonstrate a positive correlation between the expression levels of PAR and OOMT2 and the emission of 2PE and DMT. In addition, endogenous volatiles and relative transcripts showed tissue- and development-specific patterns. (C) 2014 Elsevier Masson SAS. All rights reserved.},

  abstract  = {Camellia sinensis synthesizes and emits a large variety of volatile phenylpropanoids and benzenoids (VPB). To investigate the enzymes involved in the formation of these VPB compounds, a new C. sinensis short-chain dehydrogenase/reductase (CsSDR) was isolated, cloned, sequenced, and functionally characterized. The complete open reading frame of CsSDR contains 996 nucleotides with a calculated protein molecular mass of 34.5 kDa. The CsSDR recombinant protein produced in Escherichia coli exhibited dehydrogenase-reductase activity towards several major VPB compounds in C. sinensis flowers with a strong preference for NADP/NADPH co-factors, and showed affinity for (R)/(S)-1-phenylethanol (1PE), phenylacetaldehyde, benzaldehyde, and benzyl alcohol, and no affinity for acetophenone (AP) and 2-phenylethanol. CsSDR showed the highest catalytic efficiency towards (R)/(S)-1PE. Furthermore, the transient expression analysis in Nicotiana benthamiana plants validated that CsSDR could convert 1PE to AP in plants. CsSDR transcript level was not significantly affected by floral development and some jasmonic acid-related environmental stress, and CsSDR transcript accumulation was detected in most floral tissues such as receptacle and anther, which were main storage locations of VPB compounds. Our results indicate that CsSDR is expressed in C. sinensis flowers and is likely to contribute to a number of floral VPB compounds including the 1PE derivative AP.},
