Lignin is one of the main and essential polymers in land plants. It is a prime factor of cellulosic-biomass recalcitrance to agricultural and industrial end-uses, such as lignocellulosic biofuels, ruminant digestibility, and pulp and papermaking. We are developing a lignin toolbox on one �negligible� auxiliary (ALTOONA). Toward that end, we will describe the design, synthesis, and characterization of a designer monolignol. The key feature is to install a bioorthogonal functional group at the 3-O-position of the monolignol. Importantly, this monolignol keeps the fidelity of lignification. The designer monolignol provides a platform to utilize a variety of spectroscopic approaches to reveal temporal and spatial characteristics of lignification, which is a critical step to reap the potential of the energy-rich renewable bioresource for sustainable liquid fuels and other diverse economic applications.
