#Diatom phytochromes integrate the underwater light spectrum to sense depth: Carole Duchêne et al. https://www.nature.com/articles/s41586-024-08301-3
"These photoreceptors enable them to detect changes in the light spectrum in the water column, thereby providing information regarding their vertical position within it."

Phytochromes: The 'eyes' that enable microalgae to find their way in aquatic depths
The phytoplankton that populate oceans are known to play a key role in marine ecosystems and climate regulation. Like terrestrial plants, they store atmospheric CO₂, and produce half of our planet's oxygen via photosynthesis. However, the mechanisms that control their distribution remain poorly understood.

The dual face of photoreceptors during seed germination
Seed germination depends on light in many plants. But not always: Aethionema arabicum, a plant adapted to challenging environmental conditions, does it its own way. Here, the phytochromes, the receptors for red and far-red light, play an unexpected role in seed germination and time this process to the optimal season.
Study of bryophytes reveals evolution of genetic pathways governing plant branching
Non-vascular bryophytes live in colonies that cover the ground and resemble tiny forests. In a real forest, plants compete for light in different layers of the canopy. If a plant does not receive enough sunlight, it stops lateral branching and instead grows vertically to reach the sunlight.
Go, team🔵!
