“…CCoAOMTs and COMTs catalyze the hydroxyl-methylations in the phenylpropanoids pathway [ 77 , 78 ], making them integral members of monolignol, coumarins, caffeic, and sinapic acids biosynthesis with amplified roles in plant defense [ 13 , 14 , 15 , 16 ]. For example, the OE- CCoAOMT lines in Paeonia ostii (tree peony ) and Camellia sinensis (tea plant) induce lignin production [ 13 , 14 , 15 , 16 ] for potential defense roles besides ROS scavenging and drought tolerance.…”

Fungi infections cause approximately 60–70% yield loss through diseases such as rice blast, powdery mildew, Fusarium rot, downy mildew, etc. Plants naturally respond to these infections by eliciting an array of protective metabolites to confer physical or chemical protection. Among plant metabolites, lignin, a phenolic compound, thickens the middle lamella and the secondary cell walls of plants to curtail fungi infection. The biosynthesis of monolignols (lignin monomers) is regulated by genes whose transcript abundance significantly improves plant defense against fungi. The catalytic activities of lignin biosynthetic enzymes also contribute to the accumulation of other defense compounds. Recent advances focus on modifying the lignin pathway to enhance plant growth and defense against pathogens. This review presents an overview of monolignol regulatory genes and their contributions to fungi immunity, as reported over the last five years. This review expands the frontiers in lignin pathway engineering to enhance plant defense.

“…In previous reports, we have shown that several enzyme inhibitors of the phenylpropanoid pathway such as nitecapone (Parizotto et al, 2021), entacapone (Parizotto et al, 2020), and naringenin applied in maize plants in an appropriate range of concentrations are capable to increase saccharification of maize lignocellulose without impairing growth or biomass production.…”

The burgeoning cellulosic ethanol industry necessitates advancements in enzymatic saccharification, effective pretreatments for lignin removal, and the cultivation of crops more amenable to saccharification. Studies have demonstrated that natural inhibitors of lignin biosynthesis can enhance the saccharification of lignocellulose, even in tissues generated several months post‐treatment. In this study, we applied daidzin (a competitive inhibitor of coniferaldehyde dehydrogenase), piperonylic acid (a quasi‐irreversible inhibitor of cinnamate 4‐hydroxylase), and methylenedioxy cinnamic acid (a competitive inhibitor of 4‐coenzyme A ligase) to 60‐day‐old crops of two conventional Brazilian sugarcane cultivars and two energy cane clones, bred specifically for enhanced biomass production. The resultant biomasses were evaluated for lignin content and enzymatic saccharification efficiency without additional lignin‐removal pretreatments. The treatments amplified the production of fermentable sugars in both the sugarcane cultivars and energy cane clones. The most successful results softened the most recalcitrant lignocellulose to the level of the least recalcitrant of the biomasses tested. Interestingly, the softest material became even more susceptible to saccharification.
