Anabaena sp. PCC 7120 reversibly shifts from rod-shaped cells in low light to large globular cells under high-light stress, linked to thylakoid reorganization.
- Why it matters: Cell shape in phytoplankton is often assumed to be adaptive, but how pleomorphism helps cells acclimate to changing light is not well established.
- What they did: Using molecular genetics, microscopy, physiological assays, and biophysical analyses, the study tested how elongasome and class A penicillin-binding protein activities regulate morphology across light intensities.
- The result: Globular cells reduce light absorption and maintain photosynthetic activity under photoinhibitory conditions, supporting a mechanistic link between cell-wall remodeling, cellular optics, and photosynthetic performance.
