Cyanoglobule lipid droplet accumulation as a stress response to nitrogen starvation in a non-N2-fixing mutant strain of Anabaena sp. PCC 7120.

PloS one - 1 Jan 2026

Susanto Febri A, Hiser Carrie, Mahey Mohit, Lundquist Peter K

Abstract excerpt

Cyanoglobules are lipid droplets of cyanobacteria that share compositional and functional features with plastoglobules of plant chloroplasts. However, their roles in stress physiology remain poorly defined, particularly in filamentous cyanobacteria. Here, we characterize cyanoglobule dynamics and composition during nitrogen starvation in a non-diazotrophic derivative of Anabaena sp. PCC 7120. This experimental...
