周皮充当保护植物内部组织免受生物和非生物胁迫的盔甲。它是在植物器官（如茎和根）径向增厚过程中形成的，并取代了初级保护组织（如表皮和内皮）的功能。伤口周皮也会形成以愈合和保护受伤的组织。周皮包含称为栓皮原或木栓形成层的分生组织及其衍生物：木质素化的栓皮层和栓皮层。周皮的研究主要集中在木栓的化学成分上，因为它是工业过程的原材料。如今，人们越来越关注周皮发育背后的调控网络作为一种新的育种性状，以提高植物的抗逆力和吸收二氧化碳。在这里，我们讨论目前对周皮形成的理解，重点关注周皮进化、周皮个体发生机制、胶凝蛋白起始和木栓分化的调控网络以及周皮研究的未来挑战。 《植物生物学年度评论》第 73 卷的预计最终在线发布日期为 2022 年 5 月。请参阅 http://www.annualreviews.org/page/journal/pubdates 了解修订后的估计。
The periderm acts as armor protecting the plant's inner tissues from biotic and abiotic stress. It forms during the radial thickening of plant organs such as stems and roots and replaces the function of primary protective tissues such as the epidermis and the endodermis. A wound periderm also forms to heal and protect injured tissues. The periderm comprises a meristematic tissue called the phellogen, or cork cambium, and its derivatives: the lignosuberized phellem and the phelloderm. Research on the periderm has mainly focused on the chemical composition of the phellem due to its relevance as a raw material for industrial processes. Today, there is increasing interest in the regulatory network underlying periderm development as a novel breeding trait to improve plant resilience and to sequester CO2. Here, we discuss our current understanding of periderm formation, focusing on aspects of periderm evolution, mechanisms of periderm ontogenesis, regulatory networks underlying phellogen initiation and cork differentiation, and future challenges of periderm research. Expected final online publication date for the Annual Review of Plant Biology, Volume 73 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
