Regulation of bistability in the std fimbrial operon of Salmonella enterica by DNA adenine methylation and transcription factors HdfR, StdE and StdF
(Oxford Academic, 2019-09-05)
Bistable expression of the Salmonella enterica std operon is controlled by an AND logic gate involving three transcriptional activators: the LysR-type factor HdfR and the StdE and StdF regulators encoded by the std operon ...

Contribution of DNA adenine methylation to gene expression heterogeneity in Salmonella enterica
(Oxford University Press, 2020)
Expression of Salmonella enterica loci harboring undermethylated GATC sites at promoters or regulatory regions was monitored by single cell analysis. Cell-to-cell differences in expression were detected in ten such loci ...

Ribosomal protein L14 contributes to the early assembly of 60S ribosomal subunits in Saccharomyces cerevisiae
(Oxford University Press, 2018)
The contribution of most ribosomal proteins to ribo- some synthesis has been quite well analysed in Sac- charomyces cerevisiae . However, few yeast riboso- mal proteins still await characterization. Herein, we show ...

Niche divergence and limits to expansion in the high polyploid Dianthus broteri complex
(Wiley, 2019)
Niche evolution in plant polyploids remains controversial and evidence for alternative patterns has been reported. Using the autopolyploid Dianthus broteri complex (2×, 4×, 6× and 12×) as a model, we aimed to integrate ...

Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability
(2018)
R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent ...

A novel lncRNA as a positive regulator of carotenoid biosynthesis in Fusarium
(Nature Research, 2020)
The fungi Fusarium oxysporum and Fusarium fujikuroi produce carotenoids, lipophilic terpenoid pigments of biotechnological interest, with xanthophyll neurosporaxanthin as the main end product. Their carotenoid biosynthesis ...

Soil phenanthrene phytoremediation capacity in bacteria-assisted Spartina densiflora
(Elsevier, 2019-10-30)
Polycyclic aromatic hydrocarbons (PAH) have become a threat for the conservation of wetlands worldwide. The halophyte Spartina densiflora has shown to be potentially useful for soil phenanthrene phytoremediation, but no ...

Functional diversity of motoneurons in the oculomotor system
(National Academy of Sciences, 2019-02-26)
Extraocular muscles contain two types of muscle fibers according to their innervation pattern: singly innervated muscle fibers (SIFs), similar to most skeletal muscle fibers, and multiply innervated muscle fibers (MIFs). ...

Scutoids are a geometrical solution to three-dimensional packing of epithelia
(Nature Publishing Group, 2018)
As animals develop, tissue bending contributes to shape the organs into complex three-dimensional structures. However, the architecture and packing of curved epithelia remains largely unknown. Here we show by means of ...
