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.

How do bacteria deal with double costs? And how costly are unusual levels of mistranslation anyway? In short - antibiotics are more of an issue than less/more mistranslation, but the latter changes how populations deal with antibiotics. For the long story, check out our new paper!
So happy that this work simultaneously measuring the costs of antibiotic exposure and mistranslation is finally out in MBE! Work from @deepaagashe.bsky.social (who was ultra patient!) and my labs. Do see the research highlight here, with Nishant's lovely graphic. academic.oup.com/mbe/article/...
