摘　　要：The construction of a secondary cell wall is an important and necessary developmental decision that sup- ports cell function and plant stature. Unlike the primary cell walls, which are initiated during cell division and develop along with the expansion of the cells, secondary cell walls are constructed after the cells have stopped growing. Hence, the transition from primary to secondary wall synthesis marks an important and distinct metabolic investment by the plant. This transition requires a coordi- nated change of a plethora of cellular processes, including hormonal, transcriptional and post-transcriptional activi- ties, metabolic flux re-distributions and enzymatic activities. In this review, we briefly summarize the hormonal and transcriptional control of the primary to secondary wall transition, and highlight important gaps in our under- standing of the metabolic framework that support the transition. Several tools that may aid in future research efforts to better understand the changes in cell wall synthesis during the trans-differentiation are also discussed.次生细胞壁的合成是植物的重要发育过程之一,它不仅是植物细胞实现某些特定功能所必需的,也是植物维持其形态的物质基础.与初生细胞壁不同的是次生壁的合成开始于细胞停止生长后,而初生壁的合成则是伴随细胞生长同时进行的.因此,由初生壁合成到次生壁合成的转化意味着植物体内需要进行一次重要的代谢调整.两种细胞壁合成的转化需要一系列胞内生理生化活动的协同合作.这些活动包括:激素调控、转录调控、转录后调控以及代谢通量的重分布等.本文概述了初生壁合成到次生壁合成转化所涉及的转录和激素调控,并且指出了我们对相关代谢网络认知的不足.此外,本文还对现有的可用于研究该转化的工具系统进行了讨论.
