RNA-seq analysis of apical part of elongating maize root

The dynamics of cell wall polysaccharides may modulate the cell wall mechanics and thus control the expansion growth of plant cells. The unique composition of the type II primary cell wall characteristic of grasses suggests that they employ specific mechanisms for cell enlargement. We have applied an RNA-Seq analysis to five zones in the apical part of maize root (before root hair emergence) to reveal key molecules involved in the initiation, realization and cessation of coordinated elongation growth in a plant with type II cell walls.
