Proposes non-oxygenic origins of thylakoid membranes, highlighting increased photosynthetic efficiency and electron flow in cyanobacteria.
Key Points
Thylakoid membranes enhance photosynthetic efficiency by facilitating light absorption and energy conversion, leading to effective respiration.
A specific focus on biogenesis reveals critical roles for assembly factors and evolutionary transition phases, driven by adaptation to their environment.
The analysis suggests a direct link between alternative electron flows and the development of modern thylakoid structures from ancestral forms.
Potential implications include new insights into cyanobacterial diversification, especially within toxic euxinic environments concerning photosystem II.
