This special issue comprises papers based in ameeting of theNuclear Dynamics Special Interest Group of the Society for Experimental Biology. The session was entitled ‘Functional organisation of the nuclear periphery’ and was held at the Society’s Annual Main Meeting in the beautiful city of Firenze (Florence) in July 2018. Organized by Katja Graumann and David Evans from Oxford Brookes University, Oxford UK and Roland Foisner, Medical University Vienna, Austria, the session highlighted novel research in plant, animal and fungal nuclear biology since the previous meeting of the group in Brighton, UK in 2016[1]. Themeeting was supported by attendance ofmembers of the INDEPTH (Impact of Nuclear Domains On Gene Expression and Plant Traits) COST Action CA16212 (https://www.cost.eu/actions/CA16212/). A review article in this special issue of Nucleus by members of Workgroup 1 of the COST Action provides insights into microscopy methods for studying 3D nuclear architecture in plants and accompanying challenges being addressed in the consortium[2]. Other papers highlight progress in understanding mechanisms for the dynamic organisation of the nuclear periphery, both in interphase and in dividing cells, including the role of lamina-associated domains (LADs) in spatial chromatin organization[3], the role of the nucleolus in anchoring chromatin structures [4], the contribution of structural maintenance of chromatin (SMC) complexes to chromatin organisation[5], and the function of plant KASH domain proteins in attaching the nucleus to the actin cystoskeleton[6]. The structural role of the nuclear envelope in plant mitosis and meiosis is reviewed [7] with a further paper presenting evidence for the role of lamins in meiotic chromosome movements at the nuclear periphery in C. elegans[8]. The final paper in the special issue [9] provides a comprehensive exploration of the plant nuclear proteome using a sequential extractionmethodwhich has significantly increased the number of plant nuclear proteins identified. As editors, we are grateful to all the contributors, both to the meeting and to this special issue. Their enthusiasm and willingness to share their insights and expertise with others was reflected in their presentations and is evident in the resulting papers. The cross-kingdom format of these meetings provides a fertile environment for generating research ideas and for development of collaborations and this is evidenced in the progress made by the members of the Group.

SEB佛罗伦萨特刊社论：核外围的功能组织

本期特刊包括基于实验生物学学会核动力学特别兴趣小组会议的论文。会议的主题是“核外围的功能性组织”，并于 2018 年 7 月在美丽的佛罗伦萨市（佛罗伦萨）举行的学会年度主要会议上举行。由牛津布鲁克斯大学、英国牛津和罗兰的 Katja Graumann 和 David Evans 组织Foisner，奥地利维也纳医科大学，会议重点介绍了自 2016 年在英国布莱顿举行的该小组上一次会议以来植物、动物和真菌核生物学的新研究[1]。主题会议得到了 INDEPTH（核域对基因表达和植物性状的影响）COST Action CA16212 (https://www.cost.eu/actions/CA16212/) 成员的支持。COST 行动第 1 工作组成员在本期 Nucleus 特刊中发表的一篇评论文章提供了对用于研究植物 3D 核结构的显微镜方法以及该联盟正在解决的相关挑战的见解[2]。其他论文强调了在理解核外围动态组织机制方面取得的进展，包括间期和分裂细胞，包括层相关域 (LAD) 在空间染色质组织中的作用[3]，核仁在锚定中的作用染色质结构 [4]，染色质 (SMC) 复合物的结构维持对染色质组织的贡献 [5]，以及植物 KASH 结构域蛋白在将细胞核附着到肌动蛋白囊骨架中的功能 [6]。综述了核膜在植物有丝分裂和减数分裂中的结构作用 [7]，另外一篇论文提出了核纤层蛋白在秀丽隐杆线虫核外围减数分裂染色体运动中的作用的证据 [8]。特刊的最后一篇论文 [9] 使用顺序提取方法对植物核蛋白质组进行了全面探索，该方法显着增加了鉴定的植物核蛋白质的数量。作为编辑，我们感谢所有的贡献者，包括这次会议和本期特刊。他们与他人分享他们的见解和专业知识的热情和意愿反映在他们的演讲中，并且在所产生的论文中也很明显。
