Cooperative motility, force generation and mechanosensing in a foraging non-photosynthetic diatom

Open Biology, 2023
Diatoms are ancestrally photosynthetic microalgae. However, some underwent a major evolutionary transition, losing photosynthesis to become obligate heterotrophs. The molecular and physiological basis for this transition is unclear.
