褐斑病菌AB-18-032(T)是一株产深裂霉素和近似素的放线菌，其化学分类和形态特征与其在褐斑病菌属中的分类一致。该菌在Verrucosipora 16S rRNA基因树上形成了一个明显的系统树，与Verrucosipora gifhornensis DSM 44337(T)、Verrucosipora luteaYim013(T)和Verrucosipora sim imina MS426(T)的相似性分别为99.7%、98.7%和98.9%。热变性和荧光法测得的DNAG+C含量分别为65.5%和64.0%，复性和荧光法测得的DNA值分别为64.0%和65.0%，从而与后两个种和其最近的系统发育近邻V.gifhornensis DSM 44337(T)区分开来。综合表型和基因分型结果可以看出，AB-18-032(T)菌株应归入疣状芽胞杆菌属，为一新种。命名为Verrucosipora Maris sp.11月以菌株AB-18-032(T)(=DSM 45365(T)=NRRL B-24793(T))为模式菌株。
Verrucosispora isolate AB-18-032(T), the abyssomicin- and proximicin-producing actinomycete, has chemotaxonomic and morphological properties consistent with its classification in the genus Verrucosispora. The organism formed a distinct phyletic line in the Verrucosispora 16S rRNA gene tree sharing similarities of 99.7%, 98.7% and 98.9% with Verrucosispora gifhornensis DSM 44337(T), Verrucosispora lutea YIM 013(T) and Verrucosispora sediminis MS 426(T), respectively. It was readily distinguished from the two latter species using a range of phenotypic features and from V. gifhornensis DSM 44337(T), its nearest phylogenetic neighbor, by a DNA G+C content of 65.5 mol% obtained by thermal denaturation and fluorometry and DNA:DNA relatedness values of 64.0% and 65.0% using renaturation and fluorometric methods, respectively. It is apparent from the combined genotypic and phenotypic data that strain AB-18-032(T) should be classified in the genus Verrucosispora as a new species. The name Verrucosispora maris sp. nov. is proposed for this taxon with isolate AB-18-032(T) (= DSM 45365(T) = NRRL B-24793(T)) as the type strain.
