SEPALLATA-driven MADS transcription factor tetramerization is required for inner whorl floral organ development

The paper shows that SEPALLATA-driven MADS tetramerization is essential for inner whorl floral organ identity, beyond its role in meristem determinacy.

Plant-TFClass: a structural classification for plant transcription factors

The paper classifies plant transcription factors into a structural hierarchy based on DNA-binding domain structures, adding new classes and families not present in mammals.

DNA methylation at a single cytosine embedded in the W-box cis-element repels binding of WRKY transcription factors through steric hindrance

The paper shows DNA methylation at a W-box cytosine repels WRKY TF binding through steric hindrance, using structural modeling and in vitro experiments.

Genome analysis of Parmales, a sister group of diatoms, reveals the evolutionary specialization of diatoms from phago-mixotrophs to photoautotrophs

This study compares parmalean and diatom genomes to show diatoms evolved from phago-mixotrophs to photoautotrophs by losing phagocytosis genes and gaining silica and nutrient metabolism capabilities.

The F-box cofactor UFO redirects the LEAFY floral regulator to novel cis-elements

This study identifies a novel mechanism by which the F-box protein UFO modulates the DNA-binding specificity of the master transcription factor LFY through direct interaction with novel cis-elements.

The Intervening Domain Is Required For DNA-binding and Functional Identity of Plant MADS Transcription Factors

This study shows the Intervening domain is essential for DNA-binding and functional identity of plant MADS transcription factors through structural and functional analyses.

Year-round dynamics of amplicon sequence variant communities differ among eukaryotes, Mimiviridae, and prokaryotes in a coastal ecosystem

A one-year observation of coastal microbial communities revealed similar but different community dynamics for eukaryotes, a group of large viruses, and prokaryotes.

The LEAFY floral regulator displays pioneer transcription factor properties

This study shows that LEAFY, a floral regulator in Arabidopsis, binds both methylated and non-methylated DNA and can induce chromatin accessibility in target genes.

Quantitative assessment of NCLDV-host interactions predicted by co-occurrence analyses

This study uses co-occurrence analyses to predict NCLDV hosts from Tara Oceans data, showing improved performance with a phylogeny-informed method.

Eukaryotic virus composition can predict the efficiency of carbon export in the global ocean

This study links viral community composition to carbon export efficiency in the global ocean, finding that viral marker genes explain 67% of variation in CEE.

A persistent giant algal virus, with a unique morphology, encodes an unprecedented number of genes involved in energy metabolism

This paper describes a giant algal virus with a unique morphology and an unprecedented number of genes involved in energy metabolism, including enzymes from the TCA cycle and β-oxidation pathway.
