An ancient, collinear class TI T2 RNase (EVM0017713)/F-boxes locus in the basal eudicot Akebia trifoliata is linked to the origin of the S-RNase/F-boxes system.
- Why it matters: The canonical class III T2 RNase/F-boxes S-locus is known in core eudicots, but its origin is unclear because class III T2 RNases are absent from non-eudicot lineages.
- What they did: The study identified a rare class TI T2 RNase (EVM0017713)/F-boxes locus in Akebia trifoliata and compared phylogenetic distribution, structural and physicochemical traits, gene structure, and collinearity with known S-locus components.
- The result: A continuous transition from class I to class III T2 RNase subfamilies supports an ancestral intermediate, implying the class TI locus may represent an ancestral form of the S-RNase/F-boxes system.
