Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Baboon endogenous virus genome. I. Restriction enzyme map of the unintegrated DNA genome of a primate retrovirus [PDF]

open access: yes, 1980
A detailed restriction map was deduced for the genome of an endogenous retrovirus of a higher primate, that of baboon. The cleavage sites for 12 restriction enzymes were mapped. The unintegrated linear viral DNA intermediate that is produced by infection

A SspI PCR-RFLP detecting a silent allele at the goat CSN2 locus [PDF]

open access: yes, 2005
The comparison between the cDNA sequence obtained and the published sequences of the goat CSN2 alleles showed a new single nucleotide polymorphism (SNP) (transition C-T) at the 180th nucleotide of the ninth exon.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

BioNanoAnalyst: a visualisation tool to assess genome assembly quality using BioNano data

open access: yesBMC Bioinformatics, 2017
Background Reference genome assemblies are valuable, as they provide insights into gene content, genetic evolution and domestication. The higher the quality of a reference genome assembly the more accurate the downstream analysis will be. During the last

SUMO-interacting motifs of human TRIM5α are important for antiviral activity. [PDF]

open access: yesPLoS Pathogens, 2011
Human TRIM5α potently restricts particular strains of murine leukemia viruses (the so-called N-tropic strains) but not others (the B- or NB-tropic strains) during early stages of infection.

A simple method for DNA restriction site mapping [PDF]

open access: yesNucleic Acids Research, 1976
When a DNA molecule, enzymatically labelled with 32p at one end, is partially digested with a restriction enzyme labelled tdna fragments are obtained which form an overlapping series of molecules, all with a common labelled terminus. ta restriction map can then be constructed from an analysis of the size distribution of these molecules.

Spatial search in a honeycomb network

open access: yes, 2010
The spatial search problem consists in minimizing the number of steps required to find a given site in a network, under the restriction that only oracle queries or translations to neighboring sites are allowed.

Increased variability of microbial communities in restored salt marshes nearly 30 years after tidal flow restoration [PDF]

open access: yes, 2012
We analyzed microbial diversity and community composition from four salt marsh sites that were impounded for 40–50 years and subsequently restored and four unimpounded sites in southeastern Connecticut over one growing season.
