Dynamic switching of cell-substrate contact sites allows gliding diatoms to modulate the curvature of their paths

This study shows how diatoms switch between one- and two-raphe contact gliding to modulate path curvature by dynamically altering cell-substrate contact sites.

Gliding motility of the diatom Craspedostauros australis correlates with the intracellular movement of raphid-specific myosins

This study identifies and characterizes raphid diatom-specific myosins in Craspedostauros australis, showing that only CaMyoB-D moves during gliding, suggesting a role in force generation.

Shedding light on biosilica morphogenesis by comparative analysis of the silica-associated proteomes from three diatom species

The paper identifies silica-associated proteins from three diatom species and finds that they lack commonality and show low sequence similarity, suggesting unique morphogenetic mechanisms.

Diurnal transcript profiling of the diatom Seminavisrobusta reveals adaptations to a benthic lifestyle

This study profiles the diurnal transcriptome of the benthic diatom Seminavis robusta, revealing rhythmic gene expression patterns and adaptations to its environment.

Mating type specific transcriptomic response to sex inducing pheromone in the pennate diatom Seminavis robusta

The paper identifies genes responding to sex-inducing pheromones in the diatom Seminavis robusta and links them to sexual reproduction processes.

The Seminavis robusta genome provides insights into the evolutionary adaptations of benthic diatoms

The paper reports the genome of Seminavis robusta, a benthic diatom, revealing gene family expansions and adaptations related to light and oxygen sensing, and provides insights into genetic diversity and gene function in benthic diatoms.
