economic interest. Indeed, with the current global focus on bioenergy, ligno-
cellulosic biomass represents a large renewable and sustainable source for
second-generation biofuels. The lignocellulosic biomass is mainly composed
of SW containing high amounts of lignins that constitute an obstacle to the
optimal utilization of plant species for saccharification prior to bioethanol
production. Discoveries concerning the regulation of SW formation pave the
way for designing future bioenergy crops. In such a context, TF regulating
the biosynthesis of cell wall polymers such as lignins are good candidates for
improving the saccharification of the lignocellulosic biomass.
Finally, a growing body of evidence emphasizes the importance of the
cross talk between the regulation of the developmental programme of SW
formation and the responses to both biotic and abiotic stresses (
Guillaumie
et al., 2010; Ramirez et al., 2011; Schenke et al., 2011
).
Further investigation of such cross talk might help to understand how
plants integrate stress and developmental signals to cope with their challeng-
ing environments.
