| Research Abstract |
Trees control their posture by generating the growth stress in reaction wood. Woods containing the reaction wood increase the timber cracks and the warp disturbing a fine use of wood. This study aimed to understand the reaction wood formation from the point of view of gene expression in a conifer. In the gene involved lignin synthesis, we discover the specific gene, which is expressed only when the reaction wood is formed, and designate it CoLac1. This gene is closely related to lignin increase in cell wall of reaction wood. In addition, we reveal the global gene expression of reaction wood by using next generation sequencer.
