  1.23.1.2 | metabolism |
(+)-pinoresinol/(+)-lariciresinol reductase is a pivotal branchpoint enzyme in lignan biosynthesis |
722601 |
| 1.23.1.2 | metabolism |
pinoresinol is successively converted into lariciresinol and secoisolariciresinol by PrR. Secoisolariciresinol is glycosylated to secoisolariciresinol diglucoside (SDG). PLR has enantiomeric control on the lignan biosynthetic pathway |

| 1.23.1.2 | physiological function |
LuPLR2 is involved in the early steps of (-)-secoisolariciresinol ((-)-SECO) biosynthesis and derived lignans (yatein, hinokinin, bursehernin, thujaplicatin, and matairesinol dimethyl ether) accumulated mainly in leaves. In vivo involvement of the LuPLR2 gene in the biosynthesis of (-)-yatein accumulated in flax leaves. The enzyme expression is correlated to yatein, a lignan, accumulation in plant leaves. Lignans are probably involved in plant defense mechanisms and given the presence of several cis-regulatory elements potentially involved in the plant defense response revealed by the in silico analysis of LuPLR2, presence of two MYB-binding sites in LuPLR2 |

| 1.23.1.2 | physiological function |
pinoresinol reductase catalyzes the conversion of the lignan pinoresinol to lariciresinol in Arabidopsis thaliana, where it is encoded by two genes, PrR1 and PrR2, that appear to act redundantly. The isozyme PrR2 is responsible for the synthesis of the enantiomer (-)-secoisolariciresinol |
746001 |
| 1.23.1.2 | physiological function |
recombinant expression of gene pinZ in Arabidopsis thaliana causes dynamic metabolic changes in stems, but not in roots and leaves. Expression of pinZ influenced the metabolisms of lignan and glucosinolates but not so much of neolignans such as guaiacylglycerol-8-O-4'-feruloyl ethers |
