Plant Transglutaminases: New Insights in Biochemistry, Genetics, and Physiology by Luigi Parrotta, Umesh Kumar Tanwar, Iris Aloisi, Ewa Sobieszczuk-Nowicka, Magdalena Arasimowicz-Jelonek, Stefano Del Duca

“…TGases are distributed in all plant organs, such as leaves, tubers, roots, flowers, buds, pollen, and various cell compartments, including chloroplasts, the cytoplasm, and the cell wall. Recent molecular, physiological, and biochemical evidence pointing to the role of TGases in plant biology and the mechanisms in which they are involved allows us to consider their role in processes such as photosynthesis, plant fertilisation, responses to biotic and abiotic stresses, and leaf senescence. …”

Excess manganese increases photosynthetic activity via enhanced reducing center and antenna plasticity in Chlorella vulgaris by Amanda L. Smythers, Jessica R. Crislip, Danielle R. Slone, Brendin B. Flinn, Jeffrey E. Chaffins, Kristen A. Camp, Eli W. McFeeley, Derrick R. J. Kolling

“…Additionally, manganese is a cofactor in enzymatic antioxidants, notably the superoxide dismutases—which are localized to the chloroplastic membrane. However, unlike other metals found in the photosynthetic ETC, previous research has shown exposure to excess manganese enhances photosynthetic activity rather than diminishing it. …”
