| Title | Effects of Manganese Deficiency on Spectral Characteristics and Oxygen Evolution in Maize Chloroplasts. | | Author(s) | Gong X, Wang Y, Liu C, Wang S, Zhao X, Zhou M, Li N, Lu Y, Hong F | | Institution | Medical College of Soochow University, Suzhou, People's Republic of China, 215123. | | Source | Biol Trace Elem Res 2009 Oct 20. | | Abstract | The effects of Mn(2+) deficiency on light absorption, transmission, and oxygen evolution of maize chloroplasts were investigated by spectral methods. Several effects of Mn(2+) deficiency were observed: (1) the skeleton of pigment protein complexes and oxygen-evolving center and the combination between pigment and protein were damaged; (2) the light absorption of chloroplasts was obviously decreased; (3) the energy transfer among amino acids within PS II protein-pigment complex and decreased energy transport from tyrosine residue to chlorophyll a and from chlorophyll b and carotenoid to chlorophyll a were inhibited; (4) the oxygen-evolving of chloroplast was significantly inhibited. However, Mn(2+) addition decreased the damage of light absorption, transmission, and oxygen evolution of maize chloroplasts caused by Mn(2+) deficiency. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
