1. Cellular Aspects of Lignin Biosynthesis in Xylem Vessels of Zinnia and Arabidopsis
Sammanfattning : Lignin is the second most abundant biopolymer on earth and is found in the wood (xylem) of vascular land plants. To transport the hydro-mineral sap, xylem forms specialized conduit cells, called tracheary elements (TEs), which are hollow dead cylinders reinforced with lateral secondary cell walls (SCW). LÄS MER
2. Xylem cells cooperate in the control of lignification and cell death during plant vascular development
Sammanfattning : The evolutionary success of land plants was fostered by the acquisition of the xylem vascular tissue which conducts water and minerals upwards from the roots. The xylem tissue of flowering plants is composed of three main types of cells: the sap-conducting tracheary elements (TE), the fibres which provide mechanical support and the parenchyma cells which provide metabolic support to the tissue.
