Our story describing the Panoptes bacterial immune defense system is now finally peer-reviewed and published today! www.nature.com/articles/s41...
The Panoptes system uses decoy cyclic nucleotides to defend against phage - Nature
The Panoptes antiphage system defends bacteria by detecting phage-encoded counter-defences that sequester cyclic nucleotide signals, triggering membrane disruption and highlighting a broader strategy of sensing immune evasion through second-messenger surveillance.

Amazing work by the Santiago lab @unil.bsky.social. The malectin-LRR receptor kinase IGP1 senses cello-oligomers to alert the plant immune system & enhance disease resistance. Very nice discovery & mechanism.

🧵How does a pathogen know it has entered its host?

New preprint!🎉It’s a pleasure to share my first first-author preprint from my PhD journey!
We uncover a novel co-evolved peptide–GPCR system in the fungus Ustilago maydis that senses host entry and triggers infection (doi.org/10.1101/2025...)

Editor’s Pick: Terrence H. Bell et al. believe that there is no single “best” approach to iterative microbiome passaging but that experimental design choices can have substantial impacts on outcomes. Learn more: https://doi.org/10.1094/PBIOMES-11-24-0113-P
Fig. 1. Here, we visualize how the impact of iterative microbiome passaging may differ with time.

Just an outrageous amount of structural variation in pennycress. While not yet reproductively isolated, its likely these shredded pericentromeres contribute to some reproductive incompatibilities.

Whole-genome alignments revealed pennycress has nearly dichotomous genome compartmentalization: huge gene-poor pericentromeric regions (~300Mb; <1% genic) with frequent rearrangements and highly syntenic gene-rich chromosome arms (~150Mb; ~20% genic). What we call a "two-speed" genome structure. 3/
Figure 3 | Macrosynteny and genome structure across the Brassicaceae. Horizontal blue/black/orange bands represent the chromosomes of Arabidopsis thaliana, A. lyrata, MN106, and Brassica rapa (top to bottom). Chromosomes are ordered by their number from left to right. Colors represent genomic content binned hierarchically in sliding windows (400kb-overlapping 500kb) as follow: (1) within a gene annotation (including intron and UTR, orange), (2) within EDTA-annotated repeats categorized as Ty3, (3) Ty1 (copia), (4) within another repeat category, or (5) un-annotated. Grey bands are sequence-based syntenic blocks between each pair of genomes. Pennycress and B. rapa are phylogenetically proximate (both in Brassicodae supertribe), but have reduced synteny in part because of genome reshuffling in B. rapa following a whole-genome triplication event. The seven pennycress genome assemblies (horizontal bars) are binned into TRASH-defined centromeres (orange), pericentromeres (dark blue), chromosome arms (light blue) and telomeres (dark red). The colors along the chromosome segments scale physically with the size of the bin, except that centromeres and telomeres have a 1pt buffer to make it easier to see these typically small regions. Each genome is connected to its neighbor by grey polygons that represent sequence-based syntenic blocks. Plots, genomic bins, and syntenic blocks were built with DEEPSPACE (github.com/jtlovell/DEEPSPACE).

New Zealand had some of the most restrictive laws when it came to genetically engineered food crops. This move once again demonstrates how the NZ Government makes Science-based decisions.

NZ joins other Third Countries in updating GM labeling rules: foods made with #GenomeEditing but without new DNA will no longer require a GM label. Only products with added DNA/proteins will.

In total, we show high levels of presence/absence variation in certain subclades that also tend to have arisen through proximal or tandem duplication and have a bias of positive selection in the extracellular domains. All hallmarks of genes involved in stress adaptation.

We then observed that rather than whole subfamilies showing high rates of presence-absence variation, it tends to occur in clusters within subfamiles.
Image showing the presence-absence status of each OG within the MLRR subfamilies across the 146 ecotype genomes. We observe clusters of OGs that are universally present and clusters that show high variability.

We next checked for positive selection and found that the number of non-synonymous substitutions scaled in a step-wise fashion based on pan-genome category, with core OGs showing the lowest and cloud OGs showing the highest amounts. High rates were also associated with OGs arising via TD and PD.
Graphs showing rates of non-synonomous to synonomous mutations in RLKs. Higher rates of NS to S mutations are associated with cloud or shell genome OGs and with OGs arising via TD or PD.

We also examined the mechanism of duplication that is driving RLK expansion. Once again the NLRs show high rates of tandem or proximal duplication, but several subfamilies of RLKs show even higher proportions, notably the CRKs, MLRRs, and PR5Ls.
Graph showing the percentage of OGs by RLK subfamily that have arisen via whole genome or segmental duplication, dispersed duplication, proximal duplication, and tandem duplication. In this case several groups show higher rates of tandem/proximal duplication than seen in NLRs. These include the CRKs, MLRRs, and P5RLs.

While most RLK orthogroups are present in the core or almost core collection, there are some subfamilies that show much higher proportions of OGs in the shell or cloud genomes. Compared to the intracellular NLRs, we found lower proportions in RLKs, though the MLRRs and LRK10Ls come close.
Graph showing the percentage of orthogroups from each receptor-like kinase sub-family that is present in the core, almost core, shell, and cloud genomes. The NLRs show the highest proportion of shell/cloud OGs, but the LRK10Ls and MLRRs also show high rates.

We identified all the receptor-like kinase genes present in 146 long-read Arabidopsis genomes to compile a species-wide inventory, which saturated after ~10-25 ecotypes.
Graphs of orthogroup discovery in panRLKome. Shows that natural diversity is exhausted with only 10-25 genomes, with only ~20 new OGs found be adding the remaining >100 genomes.
