“…For instance, concanamycins A and B, produced by S. scabiei, exhibit phytotoxic activity (549) and have been proposed (but not proven) to be virulence determinants in that organism. It should be noted that the other concanamycin family members are not produced in S. acidiscabies or S. turgidiscabies (548)(549)(550).…”

SUMMARYActinobacteriaare Gram-positive bacteria with high G+C DNA content that constitute one of the largest bacterial phyla, and they are ubiquitously distributed in both aquatic and terrestrial ecosystems. ManyActinobacteriahave a mycelial lifestyle and undergo complex morphological differentiation. They also have an extensive secondary metabolism and produce about two-thirds of all naturally derived antibiotics in current clinical use, as well as many anticancer, anthelmintic, and antifungal compounds. Consequently, these bacteria are of major importance for biotechnology, medicine, and agriculture.Actinobacteriaplay diverse roles in their associations with various higher organisms, since their members have adopted different lifestyles, and the phylum includes pathogens (notably, species ofCorynebacterium,Mycobacterium,Nocardia,Propionibacterium, andTropheryma), soil inhabitants (e.g.,MicromonosporaandStreptomycesspecies), plant commensals (e.g.,Frankiaspp.), and gastrointestinal commensals (Bifidobacteriumspp.).Actinobacteriaalso play an important role as symbionts and as pathogens in plant-associated microbial communities. This review presents an update on the biology of this important bacterial phylum.

“…We expected that the causal agents of scab-like diseases would produce new phytotoxin(s). As a result of our studies, a 16-membered macrolide, FD-891, was identified from the culture material of "S. cheloniumii", the agent of russet scab in Japan 23) and an anthraquinone compound, fridamycin E, from S. turgidiscabies #65, which causes netted scab in Sweden 24,25) (Fig. 7).…”

“…that produce superficial symptoms, "S. cheloniumii" was found to produce phytotoxin FD-891 (Fig. 1), which induces necrosis in potato tuber slices (Natsume et al 2005). The phytotoxin FD-891 was detected in potatoes infected by the pathogen and was also produced by other pathogenic strains of "S. cheloniumii" collected from different geographical areas in Japan.…”

“…2). We hypothesized that the different types of scab lesions on potato are caused by different phytotoxins and have been searching for them in Streptomyces strains (Natsume et al 1998(Natsume et al , 2005(Natsume et al , 2017. The aim of this study was to make a molecular level comparison of Streptomyces sp.…”

Streptomyces spp. are a highly diverse group of bacteria most of which are soil-inhabiting saprophytes. A few are plant pathogens that produce a family of phytotoxins called thaxtomins and cause significant economic losses, e.g., by reducing the marketability of potato tubers (Solanum tuberosum). In northern Europe, S. scabies, S. turgidiscabies and S. europaeiscabiei are the most common plant pathogenic species. In this study, a Streptomyces strain isolated from a netted scab lesion on a tuber of potato cv. Bintje in northern Sweden was identified as S. turgidiscabies but was found to differ in the genomic region carrying genes required for thaxtomin biosynthesis. Our results showed that the strain did not produce thaxtomin but rather phytotoxin fridamycin E, which is an anthraquinone novel to plant pathogenic Streptomyces spp. Fridamycin E was shown to reduce or inhibit sprouting of potato microtubers in vitro. While fridamycin E is known to have antibiotic activity against Gram-positive bacteria, the inhibitory activity of fridamycin E on plant growth is a novel finding.
