木材的形成是一个复杂的生物学过程，涉及五个主要的发育步骤，包括(1)被称为维管形成层的次生分生组织的细胞分裂，(2)细胞膨胀（细胞伸长和径向增大），(3)次生细胞壁沉积，(4)细胞程序性死亡，(5)心材的形成。近年来，随着木本植物基因组研究和基因工程的发展，人们对木材形成的分子机制的理解取得了新的进展。在这篇综述中，我们将重点关注两个不同的方面，木质素化过程和木纤维细胞壁微纤维角度的控制，因为它们都是木材材料性能的关键特征。(C) 2010年中国科学院。Elsevier Masson SAS出版。版权所有。
Wood formation is a complex biological process, involving five major developmental steps, including (1) cell division from a secondary meristem called the vascular cambium, (2) cell expansion (cell elongation and radial enlargement), (3) secondary cell wall deposition, (4) programmed cell death, and (5) heartwood formation. Thanks to the development of genomic studies in woody species, as well as genetic engineering, recent progress has been made in the understanding of the molecular mechanisms underlying wood formation. In this review, we will focus on two different aspects, the lignification process and the control of microfibril angle in the cell wall of wood fibres, as they are both key features of wood material properties.
