Other claims from this paper (7)
- Observation Most conserved gene pairs have species-specific cold-responsive regulation.
- Association Initial cold transcriptional responses are more conserved than later responses.
- Association In maize, genes with conserved cold responses have more promoter hypersensitive sites.
- Association Genes with conserved regulation have lower nonsynonymous to synonymous substitution ratios.
- Observation Lipid metabolism genes tended to have consistent regulation in both species.
- Observation Species-specific cold response genes did not cluster in pathways or functional categories.
- Recommendation The authors propose that species-specific cold transcriptional responses may be unreliable functional markers.
