Abstract

Amendments were proposed to the International Code of Nomenclature of Prokaryotes (ICNP) in January [Arahal et al. (2024) Int. J Syst. Evol. Microbiol. 74: 006188] that would cause major changes in the treatment of Candidatus names. The amendments introduce Section 10 to name taxa whose names cannot be validly published under the ICNP because of the absence of type strains. This section creates a parallel ‘pro-nomenclature’ and formalizes alternative material which could serve as nomenclatural types. When conspecific isolates of taxa with Candidatus names are deposited in culture collections as type strains, the names can be validly published, and it is required that the same Candidatus name be used. While the amendments are promoted to provide stable names and rules of nomenclature for uncultivated taxa, the system is deeply flawed. It removes the permanent association between names and types, which will make the meaning of names imprecise and ambiguous. It creates ‘pro-nomenclature’, which is confusing and unnecessary. Since many taxa which cannot be validly named under the ICNP can already be named under the SeqCode, it duplicates and creates overlap with an established nomenclatural system without providing tangible benefits. As the SeqCode recognizes names formed under the ICNP, the ICNP should recognize names formed under the SeqCode as they have done for the Cyanobacteria named under the International Code of Nomenclature for algae, fungi and plants (ICN). For these reasons, we urge the members of the International Committee of Systematics of Prokaryotes (ICSP) to reject these amendments.

对《国际原核生物命名法》第 10 节关于类名的拟议修正案的评论
1 月份,《国际原核生物命名法》(ICNP)提出了修正案[Arahal 等人(2024 年),Int. J Syst. Evol. Microbiol.修正案引入了第 10 节,用于命名因缺乏模式菌株而无法根据 ICNP 有效公布名称的类群。该部分创建了一个平行的 "亲命名法",并正式确定了可作为命名类型的替代材料。当带有 "Candidatus "名称的类群的同种分离物被作为模式菌株保存在培养物中时,其名称可以被有效公布,并要求使用相同的 "Candidatus "名称。虽然修正案的目的是为未栽培类群提供稳定的名称和命名规则,但该系统存在严重缺陷。它取消了名称和类型之间的永久联系,这将使名称的含义变得不精确和模糊。它创建了 "亲命名法",既混乱又不必要。由于许多在 ICNP 下无法有效命名的分类群已经可以在 SeqCode 下命名,因此它重复了既有的命名系统并造成了重叠,却没有带来实际的好处。由于 SeqCode 承认根据 ICNP 形成的名称,因此 ICNP 也应承认根据 SeqCode 形成的名称,就像他们对根据《藻类、真菌和植物国际命名规范》(ICN)命名的蓝藻所做的那样。鉴于上述原因,我们敦促国际原核生物系统学委员会(ICSP)成员拒绝接受这些修正案。

期刊介绍: Systematic and Applied Microbiology deals with various aspects of microbial diversity and systematics of prokaryotes. It focuses on Bacteria and Archaea; eukaryotic microorganisms will only be considered in rare cases. The journal perceives a broad understanding of microbial diversity and encourages the submission of manuscripts from the following branches of microbiology:
