Plastids represent the only subcellular compartment where aromatic amino acid precursors for lignin can be synthesized during secondary growth in vascular plants. Despite this, aside from a general shared understanding that plastid-localized metabolism occurs during secondary growth, virtually no research has been performed on understanding their biology. Of particular importance will be insight into their ontogeny, morphology and ultrastructure, and (given the complex cytonuclear communication required) their nuclear-encoded and organellar-encoded regulation. Updating and integrating this knowledge will contribute to our fundamental understanding of a ubiquitous developmental process in vascular plants, and a major terrestrial carbon sink, as well as carbon-related plant biotechnology. Given available evidence, we propose a new name for a distinct plastid derivative-the 'xyloplast', is required.
质体是唯⼀的亚细胞区室，在维管束植物的次级生长过程中，芳⾹族氨基酸前体可以在此合成木质素。尽管如此，除了普遍认为质体定位于次级生长过程中的代谢之外，实际上几乎没有研究⽤于了解它们的⽣物学。特别重要的是了解它们的个体发⽣、形态和超微结构，以及（考虑到需要复杂的核质通讯）它们的核编码和质体编码调控。更新和整合这些知识将有助于我们对维管束植物中普遍存在的发育过程以及主要的陆地碳汇和与碳相关的植物生物技术的基本理解。鉴于现有证据，我们建议为⼀个独特的质体衍生物取⼀个新名称——“⽊质体”。
