Photophysiological and transcriptomic response to the broad-spectrum herbicides atrazine and glyphosate in a photosynthetic picoeukaryote.

ABSTRACT: To feed the growing global population, intensive agriculture relies on herbicides to maximize productivity, but these come with broad-reaching environmental impacts, particularly deleterious effects on ecosystems through water run-off systems. Picoeukaryotes, with minimal genomes, can be employed to model the modes of action of herbicides on off-target species in the environment. Picochlorum sp. SENEW3 (P. SENEW3) is a poikilohaline green alga and serves as a useful model picoeukaryote due to its small genome and robust growth characteristics. Here, we examined the growth, photophysiological and transcriptomic responses of P. SENEW3 to sublethal concentrations of two common herbicides: atrazine and glyphosate. Atrazine treatment resulted in significant (P<0.0001
