摘要:Understanding the evolutionary mechanisms that maintain sex despite its direct costs is a long-standing challenge. Previous work has shown that sexual recombination can accelerate adaptation, in part by separating beneficial mutations from deleterious hitchhikers. However, earlier studies focused on effects of sex in a constant environment. We show that recombination provides an advantage during changing conditions in promoting the evolution of generalist phenotypes by reducing pleiotropic cos...

摘要:Conventional thermal propane dehydrogenation (PDH) faces several notable drawbacks, including high energy requirements, coking-induced catalyst deactivation, and the need for product separation. An electrocatalytic approach, using self-assembled ionic liquid (IL)-tin dioxide (SnO2) hollow spheres as the electrocatalyst, enables efficient PDH at ambient temperature. In this process, bromopropane formed in the anolyte from propane reacts with hydroxyl anions from the cathode to yield propene. Th...

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...
