In addition, traditionally it was thought that Met synthesis in plants requires transport of homocysteine from plastids to the cytoplasm, as the activity of the last enzyme of the biosynthetic pathway, MS, was found in this compartment only (Wallsgrove et al., 1983

Fe SODs are most abundantly localized inside plant chloroplasts, where they are indigenous

Author contributions AC, NS, and SK contributed to conception and design of the study

Interestingly, in one study, stress signaling transcripts strongly reacted to a single excess light trigger at 1000 mol m 2 s 1 photon flux density in non-primed Arabidopsis plants, while the same transcripts in primed plants (repeatedly pre-treated with excess light at 1000 mol m 2 s 1 ) remained largely unaffected
