BR might reveal to have a prominent interest in the role of horticultural crops. Based on extensive research BR has the ability to improve the quantity and quality of horticultural crops and protect plants against many stresses that can be present in the local environment. [16] [17] With the many advances in technology dealing with the synthesis of more stable synthetic analogues and the genetic manipulation of cellular BR activity, using BR in the production of horticultural crops has become a more practical and hopeful strategy for improving crop yields and success.

Here, we investigated the impact of lignin reduction on mechanical properties of poplar downregulated for CINNAMYL ALCOHOL DEHYDROGENASE . A comprehensive analysis of mechanical, structural, and chemical properties revealed that lignin alteration affects tensile properties, but that this effect can only be observed for cell walls with sufficiently high cellulose microfibril angle. The study deepens our understanding of the mechanical interaction of cell wall polymers and of potential challenges in unraveling the impact of cell wall engineering.
