The mycotoxin tenuazonic acid (TeA) inhibits photosynthesis and is expected to be developed as a bioherbicide to control Ageratina adenophora that is one of the most serious invasive alien plants in China. New leaves sprouting from A. adenophora at low temperatures (LT) in early spring are less sensitive to TeA compared to those growing in summer.

Biophotovoltaics (BPV) represents an innovative biohybrid technology that couples electrochemistry with oxygenic photosynthetic microbes to harness solar energy and convert it into electricity. Central to BPV systems is the ability of microbes to perform extracellular electron transfer (EET), utilizing an anode as an external electron sink. This process simultaneously serves as an electron sink and enhances the efficiency of water photolysis compared to conventional electrochemical water splitting.

Background: All chemical forms of energy and oxygen on Earth are generated via photosynthesis where light energy is converted into redox energy by two photosystems (PS I and PS II). There is an increasing number of PS I 3D structures deposited in the Protein Data Bank (PDB). The Triangular Spatial Relationship (TSR)-based algorithm converts 3D structures into integers (TSR keys).
