Mechanical strength of plants is an important agronomic
trait and directly related to the crop lodging thus yield
losses and grain quality (Ching et al. 2006; Wang et al.
2012). The intrinsic mechanical strength of plants is mainly
controlled by cell wall and any changes in cell wall
structure or composition affect the mechanical strength of
plants (Cosgrove 2000). Sclerenchymatous tissues of plants
having both primary cell wall and secondary thick cell wall
provide the maximum mechanical strength to plants (Carpita
and McCann 2000). Cellulose constitutes 20–30 % of
dry weight of primary cell walls and 40–90 % of the secondary
cell walls (Taylor et al. 1999).
