Other claims from this paper (7)
- Observation The four Arabidopsis thaliana CURT1 proteins oligomerize and are highly enriched at grana margins.
- Observation Plants without CURT1 proteins had flat lobe-like thylakoids with considerably fewer grana margins.
- Observation CURT1A overexpressors had an increased number of membrane layers (and margins) in grana.
- Observation CURT1A overexpressors had reduced grana diameter, at the expense of which membrane layers increased.
- Observation The endogenous CURT1 protein of the cyanobacterium Synechocystis sp PCC6803 can be partially replaced by its Arabidopsis counterpart.
- Observation In vitro, Arabidopsis CURT1A proteins oligomerize and induce tubulation of liposomes.
- Mechanism The authors propose that CURT1 proteins modify thylakoid architecture by inducing membrane curvature at grana margins.
