“…The presence of xanthomonadin in our identified species indicates its importance as a prominent member of the rice microbiome, alongside NPX species. Notably, a recently published study on a novel species, L. flocculans , also reported the possibility of xanthomonadin biosynthesis in this genus, as evidenced by antiSMASH results (Friedrich et al, 2023a). In the comparative analysis of the xanthomonadin BGC ( Fig.…”

“…In addition to carbohydrates, PPL193 T was also able to utilize a range of other substrates, including L-alanine, L-glutamic acid, L-serine, tetrazolium violet, tetrazolium blue, and Llactic acid. Comparison of PPL193 T with other Luteibacter species (Akter and Huq, 2018;Friedrich et al, 2023a;Friedrich et al, 2023b;Joe et al, 2023;Johansen et al, 2005;Kampfer et al, 2009;Wang et al, 2011) revealed significant differences in the metabolism of certain compounds such as α-D-glucose, D-fucose, inosine, L-Malic Acid, α-keto-butyric acid, and propionic acid (Table 1).…”

“…The family Rhodanobacteraceae is closely related to the family Lysobacteraceae ( Xanthomonadaceae ). The genus Luteibacter is characterized as Gram[negative, rod-shaped, motile, aerobic bacteria with yellow-colored colonies (Friedrich et al, 2023a). Based on the very first species, Luteibacter rhizovicinus DSM 16549 T , Johansen et al first proposed the genus Luteibacter (Johansen et al, 2005).…”

“…Based on the very first species, Luteibacter rhizovicinus DSM 16549 T , Johansen et al first proposed the genus Luteibacter (Johansen et al, 2005). As of the time of writing, it consists of nine species: L. rhizovicinus (Johansen et al, 2005), L. yeojuensis (Kampfer et al, 2009), L. anthropi (Kampfer et al, 2009), L. jiangsuensis (Wang et al, 2011), L. pinisoli (Akter and Huq, 2018), L. flocculans (Friedrich et al, 2023a), L. aegosomatis (Joe et al, 2023), L. aegosomaticola (Joe et al, 2023), and L. aegosomatissinici (Joe et al, 2023), of which three have been validly published (LPSN, http://www. bacterio.net) (Parte et al, 2020).…”

The genusLuteibacter, a member of the familyRhodanobacteraceae, encompasses Gram-negative bacteria found in diverse environments. In the present study, four yellow-pigmented bacterial isolates designated as PPL193T, PPL201, PPL552, and PPL554 were obtained and identified as Gram-negative, rod-shaped, and motile bacteria. Biochemical characterization and examination of the 16S rRNA gene sequence, derived from the genomic sequence, identified it as belonging to the genusLuteibacter. The isolates are closely related toLuteibacter yeojuensisR2A16-10T, forming a distinct monophyletic lineage withL. aegosomatisKCTC 92392TandL. anthropiCCUG25036T. The calculated values for pairwise ortho Average Nucleotide Identity and digital DNA-DNA hybridization in comparison to previously reportedLuteibacterspecies fell below the established thresholds for species delineation. As this novel species was isolated from rice seeds as a potentialXanthomonasdue to its distinctive yellow-colored colonies, we sought to identify the presence of xanthomonadin pigment in this species. Intriguingly, our findings revealed the presence of the typical peak corresponding to xanthomonadin in the UV spectra, confirming its presence in this novel species and adaptation to plant habitat. Furthermore, the detailed genomic investigation also uncovered the genomic locus corresponding to xanthomonadin biosynthetic gene cluster, further suggesting that members of this novel species are co-habitants of plant pathogenic and plant probioticXanthomonasgroup of phytobacteria within rice seeds. Apart from protease production, the species was found to produce Indole-3-Acetic Acid (IAA) in higher quantities and was also able to protect plants fromXanthomonas oryzaepv.oryzae, a major pathogen of rice indicating its probiotic nature. Genome scanning revealed the presence of genomic region(s) encoding loci for biosynthesis of anti-microbial peptides and other metabolites with probiotic properties, further confirming its probiotic properties. This study highlights the importance of using a combination of phenotypic and genotypic methods for bacterial identification and expands our knowledge of the diversity and distribution of diverse bacteria associated with rice seeds and their microbiome.Luteibacter sahniisp. nov. is proposed as a novel species of the genusLuteibacterwith PPL193T=MTCC 13290T=ICMP 24807T=CFBP 9144Tas its type strain and PPL201, PPL552, and PPL554 as other constituent members.

Various human pathogens have emerged from environmental strains by adapting to higher growth temperatures and the ability to produce virulence factors. A remarkable example of a pathoadapted bacterium is found in the genus Luteibacter, which typically comprises harmless soil microbes, yet Luteibacter anthropi was isolated from the blood of a diseased child. Up until now, nothing has been known about the specialized metabolism of this pathogen. By comparative genome analyses we found that L. anthropi has a markedly higher biosynthetic potential than other bacteria of this genus and uniquely bears an NRPS gene locus tentatively coding for the biosynthesis of a metallophore. By metabolic profiling, stable isotope labeling, and NMR investigation of a gallium complex, we identified a new family of salicylate-derived nonribosomal peptides named anthrochelins A-D. Surprisingly, anthrochelins feature a Cterminal homocysteine tag, which might be introduced during peptide termination. Mutational analyses provided insight into the anthrochelin assembly and revealed the unexpected involvement of a cytochrome P450 monooxygenase in oxazole formation. Notably, this heterocycle plays a key role in the binding of metals, especially copper(II). Bioassays showed that anthrochelin significantly promotes the growth of L. anthropi in the presence of low and high copper concentrations, which occur during infections.
