Journal ArticleDOI
Photoinhibition of Photosystem I Provides Oxidative Protection During Imbalanced Photosynthetic Electron Transport in Arabidopsis thaliana.
Yugo Lima-Melo,Yugo Lima-Melo,Vicente T.C.B. Alencar,Ana Karla Moreira Lobo,Rachel H. V. Sousa,Mikko Tikkanen,Eva-Mari Aro,Joaquim A. G. Silveira,Peter J. Gollan +8 more
TL;DR: The results of this study suggest that rapid activation of PSI photoinhibition under severe photosynthetic imbalance protects the chloroplast from over-reduction and excess ROS formation.
Journal ArticleDOI
Interaction between photosynthetic electron transport and chloroplast sinks triggers protection and signalling important for plant productivity.
TL;DR: Modifications to regulation of photosynthetic light reactions, which may be designed to improve yield in crop plants, can negatively impact metabolism and signalling, and thereby threaten plant growth and stress tolerance.
Journal ArticleDOI
Peroxisomal APX knockdown triggers antioxidant mechanisms favourable for coping with high photorespiratory H2 O2 induced by CAT deficiency in rice

TL;DR: The improved acclimation exhibited by the pAPX plants was indicated by lower H2 O2 accumulation, which was associated with lower GO activity and glyoxylate content, which may trigger favourable antioxidant and compensatory mechanisms to cope with CAT deficiency.
Journal ArticleDOI
Consequences of photosystem-I damage and repair on photosynthesis and carbon use in Arabidopsis thaliana.
Yugo Lima-Melo,Yugo Lima-Melo,Peter J. Gollan,Mikko Tikkanen,Joaquim A. G. Silveira,Eva-Mari Aro +5 more
TL;DR: The results of this study indicate that the recovery of PSI function involves the reorganization of the light-harvesting antennae, and suggest a pool of surplus PSI that can be recruited to support photosynthesis under demanding conditions.
Journal ArticleDOI
Mitochondrial GPX1 silencing triggers differential photosynthesis impairment in response to salinity in rice plants.
Yugo Lima-Melo,Fabricio E. L. Carvalho,Marcio O. Martins,Gisele Passaia,Rachel H. V. Sousa,Milton C. Lima Neto,Márcia Margis-Pinheiro,Joaquim A. G. Silveira +7 more
TL;DR: The role of a rice mitochondrial isoform (GPX1) in photosynthesis under normal growth and salinity conditions was elucidated and it was found that GPX1 could be important to salt tolerance.
