Other claims from this paper (10)
- Observation Five caleosin genes are identified from the papaya genome.
- Observation Caleosin genes from 14 representative plant species form seven orthogroups, H1–4 and L1–3.
- Observation Five CpCLO genes belong to H1 (1) and L1 (4).
- Mechanism Expansion of the L1 group is contributed to by species-specific tandem and transposed duplications.
- Mechanism Lineage-specific expansion of the caleosin family in Brassicales relative to Amborella trichopoda is largely contributed to by tandem duplication, recent WGDs and the ancient γ whole-genome triplication.
- Observation Independent gain or loss of certain introns and apparent expression divergence of caleosin genes are observed.
- Observation CpCLO2 and CpCLO5 are constitutively expressed across tissues.
- Observation Other caleosin genes appear to be tissue-specific, implying function divergence.
- Association H-form CpCLO1 and RcCLO1 show expression profiles similar to most oleosin genes, which are expressed preferentially in seeds/endosperms, shoots and calluses.
- Mechanism CpCLO1 and RcCLO1 are putatively involved in oil accumulation.
