Light/fluorescence microscopy of cells & tissues, and electron/cryo-EM imaging of macromolecular structures — a metadata catalog with a durable link back to the source archive, not a hosted image gallery. These are primary research datasets (often multi-GB to multi-TB), so this platform never downloads or stores the underlying imaging data itself. Datasets already in either source archive are ingested via accession paste/CSV at /mirroring by a Continental Admin (no automated harvesting — neither source archive supports geography-filterable search); a dataset not yet in either archive can instead be submitted directly below by any node operator, for Continental Admin review. Either way, whoever submits an accession or a self-submitted dataset is the one asserting African origin — this platform does not verify it.

Polyphasic Characterization and Biotechnological Potential of Three Novel Prochlorococcaceae (Cyanobacteria) Genera: An Integrative Taxonomic Approach Combining 16S rRNA gene, Genomic and Chemotaxonomic Analyses
BioImage Archive:S-BIAD2816 · (CIIMAR) · Panthera leo
The strains LEGE 06306, LEGE 06307, LEGE 11436, and LEGE 10375, isolated from northern Portugal, were characterized using a polyphasic taxonomic approach that included 16S rRNA gene phylogenetic analyses (ML and BI), 16S-23S ITS secondary structures, p-distance calculations, phylogenomics, morphological and ultrastructural (TEM) observations, MALDI-TOF MS profiling, as well as ecological and biochemical characterization. Although LEGE 06306, LEGE 06307, and LEGE 11436 share high 16S rRNA gene sequence similarity and display very similar morphology, the three ML and BI phylogenetic analyses revealed that these strains form three distinct lineages within the family Prochlorococcaceae, without consistent affiliation to any previously described genera. The phylogenomic analysis, ITS comparisons, and the biochemical statistical comparisons further supported the separation of these lineages. MALDI-TOF analysis revealed unique spectral profiles for each strain, while their pigment compositions were similar but varied in pigment concentrations, supporting their distinction. Based on these combined results, the three strains are described as representatives of three new cyanobacterial genera. Strain LEGE 10375 showed an uncertain placement in both the 16S rRNA and whole-genome phylogenies and therefore could not be taxonomically assigned. The high content of bioactive metabolites of the studied strains, including pigments, phenolic compounds, and sugars, positions them as sustainable sources for functional ingredients with potential applications in the food, feed, and pharmaceutical industries.

Transmission Electron Microscopy Image Data Repository for the Study: “Cry11Aa Toxin of Bacillus thuringiensis interactions with intracellular organelles in Insect gut Implicating Actin Depolymerization, Massive Endocytosis, and Vesicle Secretion“

This repository contains Transmission Electron Microscopy (TEM) datasets of mosquito larval midgut tissues, focusing on the brush border membrane (BBM) and midgut lumen regions in control larvae without toxin treatment. Samples were prepared using standard protocols for fixation, dehydration, and embedding, with larvae reared under controlled conditions prior to dissection. Ultra-thin sections (60 nm) were obtained using an ultramicrotome and stained with uranyl acetate and lead citrate to enhance contrast. Imaging was performed using a ZEISS Libra 120 Plus electron microscope operated at 80 kV, capturing ultrastructural details at magnifications ranging from 1500× to 5000×, with micrographs acquired via a GATAN UltraScan 1000 CCD camera.
