An iron-sensitive gene cluster encodes proteins that co-localize with phytotransferrin endosomes and are involved in key intracellular iron transformation and trafficking processes in a model marine diatom.

Single-cell analysis of the chloroplast redox response to high light and oxidative stress revealed light-dependent heterogeneity, and was linked to cell fate determination within isogenic diatom populations.

A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.

The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.

Mutualistic viruses called virophages are common genome inhabitants of a marine protist, where they may protect host populations from giant viruses.

High-throughput systemic approaches on long-term trends identify the environmental factors that cause loss of biodiversity and disrupt ecosystem functions.

Genomic evidence suggests that L-gulonolactone oxidase-the terminal enzyme in vitamin C synthesis, which has been repeatedly lost throughout animal evolution-was lost in plants and other photosynthetic eukaryotes following plastid acquisition.

A combination of in vivo and in vitro approaches using Xenopus eggs and embryos reveals how dimensions of mitotic chromosomes scale with decreasing cell size and increasing nuclear-cytoplasmic ratio during early embryogenesis.

Scalar irradiance microsensor measurements performed inside the tissue of living corals show that absorption and fluorescence emission by host pigments produce dramatic spectral alterations in the light environment experienced by the symbionts.

Three-dimensional fluorescence imaging of microbial eukaryotes in environmental samples allows accurate automated taxonomic profiling and quantitative data about ultrastructures and interactions of organisms.
