Wenxue Wu; Congcong Jiang; Guangqi Gao; et al. Plant Biotechnology Journal 2026. doi:10.1111/pbi.70666
Other claims from this paper (8)
- Observation The ss2 barley mutant has a shortened peduncle that traps the spike.
- Observation SS2 encodes a putative silicon efflux transporter.
- Observation SS2 transcription is higher in rachis and stem internodes.
- Observation SS2 protein localizes to the plasma membrane.
- Mechanism SS2 is required for polarized silicon partitioning.
- Observation The ss2 mutant accumulated eightfold more silicon in the peduncle than wild type.
- Observation The ss2 mutant significantly increased silicon in the flag leaf.
- Observation Tetraploid wheat lines with non-functional SS2 homologues had a similar sheathed spike phenotype.
