Here, the authors study the telomeres in Mimulus by investigating the noncoding telomerase RNA (TR), which determines the telomere sequence in eukaryotes. They find that TR duplications and divergence are linked to the evolution of multiple distinct telomere repeat types across species.

In this study, the authors use genotype data to predict environmental characteristics of maize germplasm collections and identify varieties potentially pre-adapted to target environments. They find that environment-of-origin data and genome scans for climate-associated loci offer little benefit for prioritizing accessions, despite evidence of environmental adaptation.

In this study, the authors conduct a metabolomic analysis revealing that both total anthocyanin content and the relative abundance of individual anthocyanin species contribute to fruit color variation observed between yellow- and dark red-fruited cultivars, and identify PavMYB.C2 as a key regulator controlling anthocyanin biosynthesis and Cy3G accumulation.

In this report, the author describes a novel mathematical framework for quantifying genetic buffering relationships between genes, introducing a new neutrality model that enables gene interactions to be formally defined, compared and classified across systems in a consistent and generalizable way.

In this study, the authors report that Set1-mediated cell cycle-dependent methylation of Dam1 contributes to kinetochore assembly and chromosomal stability. Dam1 methylation peaks in metaphase and is regulated by interaction with Set1 and the demethylase Jhd2, influencing chromosome segregation fidelity.

In this study, the authors develop a genetic mouse model to trace androgen receptor-expressing cells during prostate development and show that β-catenin deletion in these cells disrupts morphogenesis and activates cell death pathways.

In this study, the authors identify HarmGR13 as the gustatory receptor mediating larval responses to myo-inositol and ribose in Helicoverpa armigera, linking it to feeding behavior and sensory neuron activity.

Here, the authors investigate how sex chromosome aneuploidy in Drosophila affects traits like female fecundity and male viability, and estimate its frequency and evolutionary consequences in lab populations.

Here, the authors examine ciRS-7 across nine adenocarcinomas and find that it is largely absent from cancer cells but present in the tumor microenvironment, regulated by DNA methylation and histone acetylation.

Here the authors show that the SAF-A SAP domain and serines S14/S26 are required for XIST localization and proliferation, but not gene expression or splicing.

PLOS will always anchor our decisions in our values and our principles. And we will continue to speak up vocally for open, independent science.
We are on a mission to drive open science forward. We see the world through a lens of possibility, but we are not interested in change for the sake of change. We believe in better.
In 2025 and beyond, we will build on our catalytic legacy to effect positive change across all three of our focus areas.
A collection of free training and resources for peer reviewers of PLOS journals—and for the peer review community more broadly—drawn from research and interviews with staff editors, editorial board members, and experienced reviewers.
PLOS ONE is now accepting submissions of Lab Protocols, a peer-reviewed article collaboration with protocols.io, and Study Protocols, an article that credits the work done prior to producing and publishing results.
Open Science Indicators (OSIs) are tools developed by us in collaboration with DataSeer to measure open science behaviors such as preprint posting, data-sharing, and code-sharing in a standardized way.
We're excited about our revised and synchronized Editorial Board webpage—now enhanced with a brand-new search functionality!
Easily find and explore board members with our improved layout and seamless navigation.
We've been thrilled to welcome:
Marnie Blewitt, Giovanni Bosco, Gregory M. Cooper, Paula Cohen, Monica Colaiacovo, Danielle Garsin, Kent Hunter, Hongbin Ji, Zoltan Kutalik, Anne O'Donnell-Luria, Giorgio Sirugo, Pablo Wappner, and Fengwei Yu!
Congratulations to Associate Editor Harmit Malik, who was awarded the Edward Novitski Prize by the Genetics Society of America for his work on genetic conflict. Harmit has also been elected as a new member of the American Academy of Arts & Sciences.
