RESUMO
Lignin, which is the most important component of vascular tissue, is essential material for the structural support of higher plants and considered to play a critical role in evolution of land plants. It has been postulated that development of secondary wall is mediated by gravity. However, effects of gravity on the development and the morphology of secondary cell wall have not been well investigated. In this study, effects of averaging of gravity vector using 2-D clinostat rotation on the structure of xylem was examined. The results indicated that the morphology of xylem is regulated by the orientation of gravity vector.
