Findings reveal that NAR1 facilitates floral transition through molecular hydrogen in Arabidopsis, suggesting novel agricultural strategies.

This research aims to explore how the NAR1 gene regulates the floral transition in Arabidopsis through molecular hydrogen.
Characterization of NAR1's hydrogen-synthesizing activity through prokaryotic expression and purification.
Mutation experiments to assess the significance of cysteine residues in NAR1's catalytic activity.
Biochemical and molecular analyses of H2's role in floral transitions.
Investigation of NAR1's involvement in circadian rhythmic H2 production under light/dark cycles.
NAR1 exhibits catalytic activity for hydrogen synthesis, confirmed through protein mutation experiments.
Circadian rhythmic production of H2 was observed, linked to nitric oxide signaling.
Knockdown of NAR1 resulted in reduced H2 levels and delayed flowering.
Exogenous H2 supply and NAR1 overexpression led to early flowering, indicating its role in floral timing.
