In this work, we use the effect of herbicides that affect the photosynthetic chain at dened sites in the photosynthetic reaction steps to derive information about the uorescence emission of photosystems. The interpretation ...

Chlorophyll (Chl) loss is the main visible symptom of senescence in leaves. The initial steps of Chl degradation operate within the chloroplast, but the observation that ‘senescence-associated vacuoles’ (SAVs) contain Chl ...

A cytoplasmically inherited chlorophyll-deficient mutant of barley (Hordeum vulgare) termed cytoplasmic line 3 (CL3), displaying a viridis (homogeneously light-green colored) phenotype, has been previously shown to be ...

The development of oxygenic photosynthesis by primordial cyanobacteria ~2.7 billion years ago led to major changes in the components and organization of photosynthetic electron transport to cope with the challenges of an ...
