I am pleased to announce the publication of our latest research article titled "Far-red light regulates phototactic behavior of benthic pennate epipelic diatoms under low irradiance" in the journal Photosynthesis Research.

This paper presents part of the results obtained during the SEARCHLIGHT project (see details).

This study investigates whether benthic pennate diatoms can detect and respond to long-wavelength light within intertidal sediments. Using multispectral LED illumination, we demonstrate that red and far-red light induce upward vertical migration even at very low irradiance. These findings suggest that diatoms possess a highly sensitive, spectrally oriented light-sensing mechanism that enables them to optimize their vertical positioning within sediments.
