“…Two genes, both strongly up-regulated in phellem, code for HCBTs, a family of enzymes capable of catalyzing the synthesis of N-hydroxycinnamoyl amides such as feruloyltyramine (Yang et al, 1997). Feruloyltyramine is found in potato wound suberin (Negrel et al, 1996) and some evidence supports the hypothesis that it is also a component of the aromatic suberin in cork tree (Marques et al, 1999). HCBTs belong to the BAHD acyltransferase superfamily (D'Auria, 2006), discussed below.…”

Cork (phellem) is a multilayered dead tissue protecting plant mature stems and roots and plant healing tissues from water loss and injuries. Cork cells are made impervious by the deposition of suberin onto cell walls. Although suberin deposition and cork formation are essential for survival of land plants, molecular studies have rarely been conducted on this tissue. Here, we address this question by combining suppression subtractive hybridization together with cDNA microarrays, using as a model the external bark of the cork tree (Quercus suber), from which bottle cork is obtained. A suppression subtractive hybridization library from cork tree bark was prepared containing 236 independent sequences; 69% showed significant homology to database sequences and they corresponded to 135 unique genes. Out of these genes, 43.5% were classified as the main pathways needed for cork biosynthesis. Furthermore, 19% could be related to regulatory functions. To identify genes more specifically required for suberin biosynthesis, cork expressed sequence tags were printed on a microarray and subsequently used to compare cork (phellem) to a non-suberin-producing tissue such as wood (xylem). Based on the results, a list of candidate genes relevant for cork was obtained. This list includes genes for the synthesis, transport, and polymerization of suberin monomers such as components of the fatty acid elongase complexes, ATP-binding cassette transporters, and acyltransferases, among others. Moreover, a number of regulatory genes induced in cork have been identified, including MYB, No-Apical-Meristem, and WRKY transcription factors with putative functions in meristem identity and cork differentiation.

“…The required transferase, hydroxycinnamoyl-CoA:tyramine hydroxycinnamoyltransferase, has been found in many plants (44)(45)(46)(47). With the caveat that such units increase in stressed tobacco (48), tyramine ferulates are a logical sink for feruloyl-SCoA units that might build up when the CCR enzyme is down-regulated (Fig. 1).…”

Homologous antisense constructs were used to down-regulate tobacco cinnamyl-alcohol dehydrogenase (CAD; EC 1.1. Lignins are phenolic polymers essential for mechanical support, defense, and water transport in vascular terrestrial plants (1-3), but they are a major obstacle to efficient utilization of plants for paper making or animal feed. A recent approach toward improved utilization has been the down-regulation of enzymes involved in the lignin monomer biosynthetic pathway (Fig.

a b s t r a c tEthnopharmacological relevance: N-Alkylamides (NAAs) are a promising group of bioactive compounds, which are anticipated to act as important lead compounds for plant protection and biocidal products, functional food, cosmeceuticals and drugs in the next decennia. These molecules, currently found in more than 25 plant families and with a wide structural diversity, exert a variety of biologicalpharmacological effects and are of high ethnopharmacological importance. However, information is scattered in literature, with different, often unstandardized, pharmacological methodologies being used. Therefore, a comprehensive NAA database (acronym: Alkamid) was constructed to collect the available structural and functional NAA data, linked to their occurrence in plants (family, tribe, species, genus). Materials and methods: For loading information in the database, literature data was gathered over the period 1950-2010, by using several search engines. In order to represent the collected information about NAAs, the plants in which they occur and the functionalities for which they have been examined, a relational database is constructed and implemented on a MySQL back-end. Results: The database is supported by describing the NAA plant-, functional-and chemical-space. The chemical space includes a NAA classification, according to their fatty acid and amine structures. Conclusions: The Alkamid database (publicly available on the website http://alkamid.ugent.be/) is not only a central information point, but can also function as a useful tool to prioritize the NAA Q8 choice in the evaluation of their functionality, to perform data mining leading to quantitative structure-property relationships (QSPRs), functionality comparisons, clustering, plant biochemistry and taxonomic evaluations.
