Other claims from this paper (6)
- Observation AP1/FUL-like genes were expressed only in Joinvillea ascendens floral organs.
- Observation JaLHS1/OsMADS5 was expressed in inner and outer tepals, stamen filaments, and pistil.
- Observation SaFUL2 was expressed in all 11 or 12 primary-branch bracts of Streptochaeta angustifolia.
- Observation SaFUL2 was absent from the suppressed floral bract below the abscission zone.
- Observation SaLHS1 expression was restricted to bracts 6-11 or 12.
- Association The expression data support homology of Streptochaeta bracts 1-5 and grass glumes.
