Photosynthesis-dependent h2o2 transfer from chloroplasts to nuclei provides a high-light signalling mechanism

HIGHLIGHTS

• who: Marino Exposito-Rodriguez from the SchoolUniversity of have published the research: Photosynthesis-dependent H2O2 transfer from chloroplasts to nuclei provides a high-light signalling mechanism, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
• what: Using the H2O2 specific probe HyPer2 targeted to chloroplasts and nuclei the authors show that chloroplast-sourced H2O2 is transferred to nuclei where it may act as a signal to induce HL-responsive gene_expression.
• how: The CF image data were collected over a range of PPFD (0 100 200 300 400 500 µmol m-2 s-1).
