Antiviral reverse transcriptases reveal the evolutionary origin of telomerase Defense-associated reverse transcriptases (DRTs) employ diverse and distinctive mechanisms of cDNA synthesis to protect bacteria against viral infection. However, much of DRT family diversity remains ...

1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?

Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria.

Exploring fern pathosystems and immune receptors to bridge gaps in plant immunity - BMC Biology Land plants include angiosperms, gymnosperms, bryophytes, lycophytes, and ferns, each of which may deploy distinct strategies to resist pathogens. Here, we investigate fern-pathogen interactions by characterizing novel pathosystems and analyzing the diversity of fern immune receptors. A collection of fern species was inoculated with a diverse set of filamentous microbes, and disease symptoms were assessed. We further leveraged published genome mining tools to analyse the diversity of receptor-like kinases, receptor-like proteins (RLKs/RLPs) and nucleotide-binding and leucine-rich repeats (NLRs), along with key immune signalling components, in ferns. Our results reveal that ferns exhibit a range of responses to pathogens, including putative non-host resistance and more specific resistance mechanisms. Among ten ferns tested, Pteris vittata displays the broadest spectrum of pathogen compatibility. Genome mining indicates that ferns encode a diverse repertoire of putative immune receptors, antimicrobial peptides, and mediators of systemic acquired resistance. Ferns possess numerous RLKs/RLPs, resembling those required for cell-surface immunity in angiosperms. They also encode diverse NLRs, including sub-families lost in flowering plants. These findings provide insights into disease resistance evolution and open promising perspectives for crop protection strategies.

Fig. 2.Confocal microscopy of N. punctiforme strains. Filaments from the indicated strains were taken from cultures grown in BG110 medium (not induced; A) or after incubation for 24 h in the presence of Anthoceros agrestis exudates (hormogonia induction; B) and visualized by confocal microscopy. Merged (2 channels) show the overlay of autofluorescence (magenta) and GFP fluorescence (green). Merged (3 channels) represent the overlay of magenta autofluorescence, bright field, and green GFP fluorescence. Hormogonia are identified as short filaments with small cells. Scale bar=20 μm.

Neubauer et al. developed a Nostoc reporter strain enabling high-throughput quantitative monitoring of hormogonia differentiation in cyanobacteria as a response to biotic and abiotic factors.
