Long-Read Genome Sequence of the Sugar Beet Rhizosphere Mycoparasite .

is a soil born free living oomycete able to parasitize fungi and oomycetes prey, including important plant and animals pathogens. can colonize endophytically the root tissues of diverse plants where it induces plant defenses. Here we report the first long-read genome sequencing of a strain sequenced by PacBio technology.

Phyllosphere Colonization by a Soil sp. Promotes Plant Defense Responses Against Fungal Infection.

Streptomycetes are soil-dwelling, filamentous actinobacteria and represent a prominent bacterial clade inside the plant root microbiota. The ability of streptomycetes to produce a broad spectrum of antifungal metabolites suggests that these bacteria could be used to manage plant diseases. Here, we describe the identification of a soil strain named AgN23 which strongly activates a large array of defense responses when applied on leaves.

Genomics analysis of Aphanomyces spp. identifies a new class of oomycete effector associated with host adaptation.

Background: Oomycetes are a group of filamentous eukaryotic microorganisms that have colonized all terrestrial and oceanic ecosystems, and they include prominent plant pathogens. The Aphanomyces genus is unique in its ability to infect both plant and animal species, and as such exemplifies oomycete versatility in adapting to different hosts and environments. Dissecting the underpinnings of oomycete diversity provides insights into their specificity and pathogenic mechanisms.

Optimization of multiplexed RADseq libraries using low-cost adaptors.

Reduced representation genomics approaches, of which RADseq is currently the most popular form, offer the possibility to produce genome wide data from potentially any species, without previous genomic information. The application of RADseq to highly multiplexed libraries (including numerous specimens, and potentially numerous different species) is however limited by technical constraints. First, the cost of synthesis of Illumina adaptors including molecular identifiers (MIDs) becomes excessive when numerous specimens are to be multiplexed.
