How do plant-associated #microbiota regulate #plant hormones? @leidai_CAS &co reveal that #bacteria associated with #Arabidopsis & rice roots can degrade the #auxin IAA, mitigating the root inhibition caused by IAA-producing bacteria #PLOSBiology https://plos.io/3Oqzgaq

Some ancient divergences in #Opisthokonta (animals, fungi & their unicellular pals) remain contentious. Hongyue Liu @RokasLab Yuanning Li &co present a genome-scale #phylogeny & establish the geological timeline of #opisthokont diversification #PLOSBiology https://plos.io/3XrOD6U


.@bphmetz explores a #PLOSBiology study which uses in silico rewiring of #GeneticCodes & functional protein data to reveal a positive correlation between #robustness & protein #evolvability. Primer: https://plos.io/3K8lIP0 Paper: https://plos.io/4dXt85p


Where do new genes come from? @HassanZaman91 @barricklab &co show that within the timescale of the #LTEE experiment, the co-option of #promoters, mainly from #TransposableElements, serves as the major source of raw material for #DeNovoGenes #PLOSBiology https://plos.io/4a8p6DT


How cells ensure an accurate 3' end for 18S rRNA. @RobinStanleyLab explores a #PLOSBiology study which reveals multiple checkpoints that ensure only #ribosomes containing the correct 3' end participate in translation. Primer: https://plos.io/4dmcv2L Paper: https://plos.io/3UNnn2F


#Bacterial acquisition of #zinc. @Ignacio_Luque_R @cyanofur &co reveal that a previously unstudied exoprotein from #cyanobacteria is an ancient system for Zn2+ acquisition that has been well conserved for billions of years #PLOSBiology https://plos.io/3PkyfBU


The move from a free-living environment to an endosymbiotic relationship has profound effects on bacterial function.

This #PLOSBiology Unsolved Mystery from John P McCutcheon &co explores how bacterial endosymbionts work with so few genes. #symbiosis

#Bacteriophages encode anti-CRISPR proteins that inactivate bacterial #CRISPR-Cas systems, allowing successful invasion, replication & integration. This study shows that #antiCRISPR protein AcrIIA1 induces degradation of #Cas9 in human cells #PLOSBiology https://plos.io/3uUGAos


#Phages are key drivers of #MicrobialEvolution, but many #phage genes are poorly understood. @denish_piya @AdamArkinLab @vivek_mutalik &co use arrayed genome-wide #CRISPRi to map gene the essentiality landscape in the iconic coliphages λ & P1. #PLOSBiology https://plos.io/3uLtzgU


The human #OAS1 protein restricts #SARSCoV2 replication, but #HorseshoeBat OAS1 has lost this ability. @spyroslytras @WilsonLabCVR &co resurrect the 60,000,000 yr old ancestral bat OAS1, revealing how this ancient #antiviral mechanism was lost #PLOSBiology https://plos.io/3N6fWPx


How many #species are there on Earth? Projections have ranged from the millions to the trillions.

This Perspective looks at how a 2011 #PLOSBiology study transformed this field and what still needs to be done to find a definitive answer.

The #symbioses that gave rise to primary #organelles are key events in the origin of #Eukaryotes. @PierreSGarcia @FredBarras & @SGribaldo use markers from 2 conserved machineries for [Fe-S] cluster biogenesis to support an early emergence of #mitochondria & #plastids within #Alphaproteobacteria & #Cyanobacteria #PLOSBiology https://plos.io/3FNP5E5


How do sunflowers track the sun during the day? Light manipulation & transcriptomics reveals that #sunflowers use multiple #photoreceptors & distinct growth pathways to generate daytime & nighttime bending movements during #heliotropism #PLOSBiology https://plos.io/46VpHbc


Organisms use a range of defense systems against #parasites. Using a #bacteria-#phage model system, @drbridgetwatson @edzewestra &co ask what drives the transient evolution of different systems; implications for #HostEcology & #pathogenicity #PLOSBiology https://plos.io/3LoFSoM


#Aspergillus fumigatus, a saprotrophic #fungus that can cause serious life-threatening invasive infections, smashes the record for number of meiotic crossovers... ~30 per #chromosome (>2x the previous record holder) @TheRedBen @EvelineSnelders #PLOSBiology https://plos.io/3rc3k1L

Analysis of 10k peer reviews reveals that those for high-#ImpactFactor #journals pay more attention to Materials/Methods but less to Presentation/Reporting (those for low-#JIF journals emphasize solutions) @annasvrn @eggersnsf @ste_mueller &co #PLOSBiology https://plos.io/45tDVzz


Into the #Unknome. The function of many human genes still remains mysterious; @mjafreeman, Sean Munro &co present an “Unknome database,” and show that screens focusing on the "Unknome" can shed light on fundamental biological processes #PLOSBiology https://plos.io/3YqumhS


#Rotifers have been studied for >100 years re #microevolution, #EcologicalDynamics & #ecotoxicology. This study presents a #CRISPR-based method for KO mutation of 1 or 2 alleles, and KI mutations, in rotifers with high efficiency @MBLscience #PLOSBiology https://plos.io/3Kb8CAC


Movement proteins enable cell-to-cell transfer of #plant RNA & DNA viruses via #plasmodesmata. @Butkovic_A @mkrupovic &co show that 30K movement proteins originated from #virus #JellyRoll capsid proteins, emphasizing the key role of exaptation #PLOSBiology https://plos.io/3NxGsBX


Why are #MultipartiteViruses so widespread, given the apparent costs of this form of genome organization? @AsherLeeks @StuWest8 &co show that selection for cheats can drive the #evolution of multipartite #viruses under realistic conditions #PLOSBiology https://plos.io/3Lshrax

Hi Fediverse! 👋

We are very happy to be here! For those of us who don't know us, #PlosBiology is an #OpenAccess, #nonprofit scientific journal.

We are the PLOS flagship in the #LifeSciences. Our policies aim to depressurize de publication process & increase transparency. As all of PLOS, we're staunch promoters of #OpenScience.

Take a look at our current issue, with a gorgeous photo on the cover taken by one of our staff editors when she lived in #SouthAfrica
