Feeling stretched or compressed? The multiple mechanosensitive responses of wood formation to bending.

ABSTRACT:

Background and aims

Trees constantly experience wind, perceive resulting mechanical cues, and modify their growth and development accordingly. Previous studies have demonstrated that multiple bending treatments trigger ovalization of the stem and the formation of flexure wood in gymnosperms, but ovalization and flexure wood have rarely been studied in angiosperms, and none of the experiments conducted so far has used multidirectional bending treatments at controlled intensities. Assuming that bending involves tensile and compressive strain, we hypothesized that different local strains may generate specific growth and wood differentiation responses.

Methods

Basal parts of young poplar stems were subjected to multiple transient controlled unidirectional bending treatments duri
