Thermospermine working model

Caption

Thermospermine requires m3U2952 modification of ribosomes for its bifunctional translation regulation. In WT plants the OVAC gene can methylate ribosomes (m3U2952). With this specific methylation and the presence of themospermine, SACLs can be translated but LHW cannot. This mechanism is impaired in the ovac mutant where SACLs are not translated, but LHW can still be translated.
