摘要

长丝状细胞的生产和生长，即菌丝，通过顶端延伸是大多数真菌的标志。这种极化生长需要一个强大的分泌系统来传递物质，如膜成分、蛋白质和细胞壁前体，到生长尖端。这个过程的核心是Spitzenkörper （SPK）的形成，这是一个位于菌丝顶端的结构。SPK在担子菌门和子囊菌门以及芽生菌门和动物菌门的一些成员中观察到最多。它由分泌囊泡、细胞骨架元件和信号蛋白的动态组合组成。本文综述了目前对SPK结构和功能的认识，并概述了该领域未来的研究方向。

One hundred years of the Spitzenkörper: A story in three acts

The production and growth of long filamentous cells, i.e., hyphae, via apical extension is a hallmark of most fungi. This polarized growth requires a robust secretory system to deliver materials, such as membrane components, proteins, and cell wall precursors, to the growing tip. Central to this process is the formation of the Spitzenkörper (SPK), a structure located at the hyphal apex. The SPK is most observed in species from the Basidiomycota and Ascomycota, as well as in some members of the Blastocladiomycota and the Zoopagomycota. It is composed of a dynamic assembly of secretory vesicles, cytoskeletal elements, and signaling proteins. This review explores the current understanding of SPK structure and function and outlines future directions for advancing research in this area.

期刊介绍： Fungal Genetics and Biology, formerly known as Experimental Mycology, publishes experimental investigations of fungi and their traditional allies that relate structure and function to growth, reproduction, morphogenesis, and differentiation. This journal especially welcomes studies of gene organization and expression and of developmental processes at the cellular, subcellular, and molecular levels. The journal also includes suitable experimental inquiries into fungal cytology, biochemistry, physiology, genetics, and phylogeny. Fungal Genetics and Biology publishes basic research conducted by mycologists, cell biologists, biochemists, geneticists, and molecular biologists. Research Areas include: • Biochemistry • Cytology • Developmental biology • Evolutionary biology • Genetics • Molecular biology • Phylogeny • Physiology.
