Figure 1
Pathway and strategy toward incorporating p-coumaraldehyde into lignin in Arabidopsis. Schematic representation of the monolignol biosynthetic pathway, in which the route toward p-coumaryl alcohol is highlighted. The figure of the lignin pathway was taken from Figure 1 of Muro-Villanueva et al. (2022). The stacking strategy is shown in the upper right panel: the H-enriched lignin genotype (med5a/5b ref8–1) was crossed with the aldehyde-rich lignin genotype (cadc cadd) to generate the quintuple mutant med5a/5b ref8–1 cadc cadd. Legend for the mutants: med5a/5b, double mutant for the MEDIATOR subunits 5a and 5b; ref8–1, single mutant for the lignin biosynthetic gene C3′H; cadc cadd, double mutant for the lignin biosynthetic genes CAD. Legend for the enzymes in the pathway: PAL, PHENYLALANINE AMMONIA LYASE; C4H, CINNAMATE 4-HYDROXYLASE; 4CL, 4-COUMARATE:COENZYME A LIGASE; HCT, p-HYDROXYCINNAMOYL-COENZYME A:QUINATE/SHIKIMATE p-HYDROXYCINNAMOYLTRANSFERASE; CSE, CAFFEOYL SHIKIMATE ESTERASE; CCoAOMT, CAFFEOYL-COENZYME A O-METHYLTRANSFERASE; F5H, FERULATE 5-HYDROXYLASE; and COMT, CAFFEIC ACID O-METHYLTRANSFERASE.
