摘要:Understanding how cells make decisions over time requires the ability to link past molecular states to future phenotypic outcomes. We present TimeVault, a genetically encoded system that records and stores transcriptomes within living mammalian cells for future readout. TimeVault leverages engineered vault particles that capture messenger RNA through polyadenosine [poly (A)]-binding protein. We demonstrate that the transcriptome stored by TimeVaults is stable in living cells for more than 7 da...

摘要:Eukaryotic gene expression is orchestrated by RNA polymerases (RNAPI, II, and III) and associated factors, yet their real-time dynamics remain obscure. Using single-molecule tracking in living yeast, we quantified the kinetics of 58 proteins encompassing three RNAP machineries. RNAPI and RNAPIII preinitiation complexes (PICs) engage in long-lived chromatin interactions, contrasting with transient RNAPII PICs. We further report kinetics of RNAPII-associated factors for elongation, histone modif...

摘要:Populations that are declining as a result of climate change may need to evolve to persist. Although evolutionary rescue has been demonstrated in theory and in the laboratory, its relevance to natural populations facing climate change remains unknown. Here we link rapid evolution and population dynamics in scarlet monkeyflower, Mimulus cardinalis, during exceptional drought. We leverage whole-genome sequencing across 55 populations to identify climate-associated loci. Simultaneously we track d...

摘要:In many algae, photosynthesis is boosted by biophysical CO2-concentrating mechanisms, which pack the CO2-fixing enzyme Rubisco into liquid-like organelles called pyrenoids. Engineering C3 crops with algal pyrenoids could increase yields, but progress is hampered by the deep evolutionary divide between crops and algae. Here, we show that hornworts, the only land plants with pyrenoids, have an unusual Rubisco small subunit, RbcS-STAR, the C-terminal coiled-coil domain of which oligomerizes to me...
