Abstract：
Cyanobacteria are globally widespread photosynthetic prokaryotes and are major contributors to global biogeochemical cycles. One of the most critical processes determining cyanobacterial eco-physiology is cellular death. Evidence supports the existence of controlled cellular demise in cyanobacteria, and various forms of cell death have been described as a response to biotic and abiotic stresses. However, cell death research in this phylogenetic group is a relatively young field and understanding of the underlying mechanisms and molecular machinery underpinning this fundamental process remains largely elusive. Furthermore, no systematic classification of modes of cell death has yet been established for cyanobacteria. In this work, we analyzed the state of knowledge in the field of cyanobacterial cell death. Based on that, we propose unified criterion for the definition of accidental, regulated, and programmed forms of cell death in cyanobacteria based on molecular, biochemical, and morphologic aspects following the directions of the Nomenclature Committee on Cell Death (NCCD). With this, we aim to provide a guide to standardize the nomenclature related to this topic in a precise and consistent manner, which will facilitate further ecological, evolutionary, and applied research in the field of cyanobacterial cell death.
摘要：
蓝细菌是全球广泛分布的光合原核生物，是全球生物地球化学循环的主要贡献者。决定蓝细菌生态生理学的最关键过程之一是细胞死亡。证据支持蓝细菌中存在受控的细胞死亡，和各种形式的细胞死亡已被描述为对生物和非生物胁迫的反应。然而,这个系统发育群体中的细胞死亡研究是一个相对年轻的领域，对支撑这一基本过程的潜在机制和分子机制的理解在很大程度上仍然难以捉摸。此外，尚未建立蓝藻细胞死亡模式的系统分类。在这项工作中,我们分析了蓝细菌细胞死亡领域的知识状况。基于此,我们为偶然的定义提出了统一的标准，受管制,以及基于分子的蓝藻细胞死亡的程序性形式，生物化学，和形态学方面遵循细胞死亡命名委员会（NCCD）的指导。有了这个,我们的目标是提供一个指南，以精确和一致的方式标准化与该主题相关的术语，这将促进进一步的生态，进化，以及在蓝藻细胞死亡领域的应用研究。
