Machado R, Abolafia J, Robles M, Ruiz-Cuenca A, Bhat A, Shokoohi E, et al.
Parasit Vectors . 2025 Mar; 18(1):101. PMID: 40069896
Background: Heterorhabditis are important biological control agents in agriculture. Two Heterorhabditis populations, S8 and S10, were isolated from agricultural soils in the United States of America. Molecular analyses, based on...

Machado R, Muller A, Hiltmann A, Bhat A, Puza V, Malan A, et al.
Mol Phylogenet Evol . 2025 Jan; 204:108284. PMID: 39778636
Multigene, genus-wide phylogenetic studies have uncovered the limited taxonomic resolution power of commonly used gene markers, particularly of rRNA genes, to discriminate closely related species of the nematode genus Heterorhabditis....

Thanwisai A, Machado R, Bhat A, Pidot S, Tandhavanant S, Subkrasae C, et al.
Curr Microbiol . 2024 Nov; 82(1):10. PMID: 39586874
Four Gram-stain-negative bacterial strains, CS20, AUT15.5, XENO-11, and CCN3.3, isolated from Steinernema entomopathogenic nematodes, were found to represent novel species within the genus Xenorhabdus (Gammaproteobacteria, Morganellaceae). In this study, we...

Arce C, Machado R, Mamin M, Glauser G, Bruno P, Benrey B, et al.
Curr Biol . 2024 Nov; 34(23):5417-5428.e4. PMID: 39504964
Many specialized herbivorous insects sequester single classes of toxic secondary metabolites from their host plants as protection against natural enemies. If and how herbivores can use multiple classes of plant...

Machado R, Malan A, Abolafia J, Ewany J, Bhat A, Stock S
Curr Microbiol . 2024 Oct; 81(12):423. PMID: 39443328
A novel bacterial species, Photorhabdus viridis sp. nov., represented by strain Green, isolated from Heterorhabditis zealandica MJ2C entomopathogenic nematodes, is described. Phylogenetic reconstructions using 16S rRNA gene sequences show that...

Muller A, Morales-Montero P, Boss A, Hiltmann A, Castaneda-Alvarez C, Bhat A, et al.
Cell Rep . 2024 Oct; 43(10):114817. PMID: 39365701
Enormous efforts have been made to understand the functions of bioluminescence; however, its relevance in soil ecosystems has barely been investigated. In addition, our understanding of the biological relevance of...

Bouras N, Machado R
PLoS One . 2024 Aug; 19(8):e0307299. PMID: 39173039
The classification of Microbispora, a bacterial genus of significant ecological, agricultural, biotechnological, and clinical importance, has traditionally been carried out based on 16S rRNA gene sequences or phenotypic characteristics, which...

Puza V, Machado R
Zoological Lett . 2024 Jul; 10(1):13. PMID: 39020388
Entomopathogenic nematodes of the genera Steinernema and Heterorhabditis, along with their bacterial symbionts from the genera Xenorhabdus and Photorhabdus, respectively, are important biological control agents against agricultural pests. Rapid progress...

Zhong J, Zhang J, Zhang Y, Ge Y, He W, Liang C, et al.
BMC Plant Biol . 2024 Jul; 24(1):677. PMID: 39014327
Climate change is predicted to increase the occurrence of extreme weather events such as heatwaves, which may thereby impact the outcome of plant-herbivore interactions. While elevated temperature is known to...

Machado R, Malan A, Boss A, Claasen N, Bhat A, Abolafia J
Curr Microbiol . 2024 Jun; 81(8):240. PMID: 38910178
One Gram-negative, rod-shaped bacterial strain, isolated from an undescribed Heterorhabditis entomopathogenic nematode species was characterized to determine its taxonomic position. The 16S rRNA gene sequences indicate that it belongs to...
