“…Examples of these crops include miscanthus, switchgrass, poplar or willow, which share a sequenced genome; but also herbaceous and woody biomass species for which genetic resources are even more scarce, as giant reed, reed canary grass, black locust, and siberian elm ( Pancaldi and Trindade, 2020 ). These crops should therefore be improved, and a preeminent target trait is certainly cell wall quality, which is the major determinant of biomass quality for bio-based applications ( Van Der Weijde et al, 2013 ; Isikgor and Becer, 2015 ; Van Der Cruijsen et al, 2021 ). Specifically, the total content of the major cell wall components – cellulose, hemicelluloses, and lignin – as well as cellulose cristallinity, degree and type of hemicellulose substitutions, and the monolignol composition of the lignin polymers are all target characters at the basis of biomass quality ( Van Der Weijde et al, 2013 ; Van Der Cruijsen et al, 2021 ).…”
