Other claims from this paper (9)
- Observation GRXS17 was found in the nucleus and cytosol.
- Observation GRXS17 expression was elevated in shoot meristems and reproductive tissues.
- Observation Recombinant GRXS17 bound Fe2S2 clusters.
- Intervention effect GRXS17 complemented defects of a yeast GRX5 deficient strain.
- Observation The grxs17 knockout had a minor decrease in iron-sulfur enzyme activities.
- Intervention effect High temperature and long-day photoperiod together arrested growth.
- Observation NF-YC11/NC2α was identified as a GRXS17 partner.
- Observation An NF-YC11/NC2α deficient mutant had photoperiod response phenotypes similar to grxs17.
- Mechanism The authors propose GRXS17 and NF-YC11/NC2α relay a photoperiod redox signal to maintain meristem function.
