- Abstract
- Phenylalanine ammonia-lyase (PAL), Cinnamic acid 4-hydroxylase (C4H) and
4-Coumarate: CoA ligase (4CL) catalyze the first three steps of the general phenylpropanoid
pathway whereas chalcone synthase (CHS) catalyzes the first specific step towards flavonoids
production. This class of specialized metabolites has a wide range of biological functions
in plant development and defence and a broad spectrum of therapeutic activities for human
health. In this study, we report the isolation of hemp PAL and 4CL cDNA and genomic
clones. Through in silico analysis of their deduced amino acid sequences, more than an
80% identity with homologues genes of other plants was shown and phylogenetic
relationships were highlighted. Quantitative expression analysis of the four above
mentioned genes, PAL and 4CL enzymatic activities, lignin content and NMR metabolite
fingerprinting in different Cannabis sativa tissues were evaluated. Furthermore, the use of
different substrates to assay PAL and 4CL enzymatic activities indicated that different
isoforms were active in different tissues. The diversity in secondary metabolites content
observed in leaves (mainly flavonoids) and roots (mainly lignin) was discussed in relation
to gene expression and enzymatic activities data. (literal)
