Restoration of electron flow and oxygen-evolution quantity of Mn-depleted photosystem 2 (PS2) was performed with using synthetic manganese complexes Mn(im)6Cl2, Mn(im)2Cl2, Mn(5-Clsalgy)2, and Mn(salgy)2 instead of original manganese cluster for reconstruction of electron transport and oxygen evolution. and M.

Chlorophyll fluorescence parameters (Fv/Fm, RFd) of nine bryophyte and one lichen species were investigated after prolonged exposure to elevated UV-B radiation. The majority of the investigated bryophytes showed a prompt or inducible tolerance to increase UV-B irradiation. Among the investigated species high degree of UV-tolerance coincides with strong desiccation tolerance. and Z. Csintalan ... [et al.].
