Title
No Evidence Supports the Presence of SRF-type MADS-Box Genes in Land Plants
Yichun Qiu; Zhen Li; Claudia Köhler Genome Biology and Evolution 2026. doi:10.1093/gbe/evag140
Other claims from this paper (3)
- Observation Phylogenetic and structure-prediction analyses show that both Type I and Type II MADS-box genes are plant-specific duplicates derived from MEF2-type ancestors.
- Observation Reanalysis of the earlier study data found no support for the hypothesis of a polyphyletic origin of plant Type I genes.
- Observation Phylogeny, sequence similarity and structural evidence show no evidence of SRF-derived genes in land plants.
