Here, we find that many Genomic islands have origins of transfer (oriT) mobilisable by conjugation, incl. known Pathogenicity & defense islands. iOriT use only an oriT for transfer by hitching on conjugative elements: they make abundant, diverse, ancient families of mobile genetic elements. See🧵
Bacteria chromosomes contain Genomic Islands that provide virulence, antibiotic resistance, MGE-defence,... They transfer between cells, but the mechanism of most remains elusive.

Here we explore the conjugative capacity of these mysterious Genomic Islands.

The final form of my 2nd postdoc paper with the Bassler Lab! Turns out our favorite quorum-sensing phage isn’t a one-off, but rather a member of a globally dispersed family of phages that sense a universal autoinducer.

Bacterial genomes encode a rich repertoire of antiphage systems, but we still know surprisingly little about when these systems are actually expressed.

In this preprint, Lucas Paoli et al, ask what shapes antiphage systems expression in native contexts.

Environment and physiology shape antiphage system expression
Bacteria and archaea encode on average ten antiphage systems. Quorum sensing, cellular, or transcription factors can regulate specific systems (CRISPR-Cas, CBASS). Yet, a systematic assessment of anti...

Phages are full of genes of unknown function that are likely adaptive in specific conditions.

Check out our latest paper on mirusviruses, one of the most remarkable new groups of protist viruses - extremely diverse, carry lots of spliceosomal introns (including new homing introns) and are at the evolutionary crossroads between tailed phages and herpesviruses! www.nature.com/articles/s41...
Widespread and intron-rich mirusviruses are predicted to reproduce in nuclei of unicellular eukaryotes - Nature Microbiology
Environmental metagenomic explorations show that Mirusviricota lineages lack essential replication and transcription genes and contain spliceosomal introns, suggesting nuclear reproduction.

Just got an email from my SRO for the study section that was missed in October. Good news is that they are trying to reschedule ASAP (Dec/Jan). The bad news is that CSR is mandating that only the the top third (not half) of applications will get discussed for the next 2 rounds.
