Other claims from this paper (10)
- Observation SLEEPER genes were found only in angiosperms.
- Observation Basal angiosperms, grasses and dicotyledonous plants have putative SLEEPER orthologs.
- Observation SLEEPER-family genes were not detected in gymnosperms, mosses or algae.
- Observation Most species carry more than one SLEEPER gene.
- Observation All SLEEPER proteins contain BED-zinc finger and hATC dimerization domains.
- Intervention effect Grapevine and rice SLEEPER constructs failed to complement the Arabidopsis daysleeper phenotype.
- Intervention effect Those constructs produced a dominant phenotype in Arabidopsis.
- Intervention effect Rice insertion lines at RICESLEEPER1 or 2 showed developmental abnormalities.
- Observation A rice retroposition event gave rise to RICESLEEPER1 and 2.
- Mechanism The ancestral SLEEPER gene was proposed to arise by retro-transposition in early angiosperms.
