Genbank accession number
- Key message
- The results suggest that the role of OsHAK26 in maintaining pollen development and fertility may relate to its proper cargo sorting for construction of pollen walls, while the role of OsHAK1 and OsHAK5 in maintaining seed production likely relates to their transcellular K+ transport activity
- Knockout of either OsHAK26 or plasma membrane located H+-K+ symporter gene OsHAK1 or OsHAK5 in both Nipponbare and Dongjin cultivars caused distorted anthers, reduced number and germination rate of pollen grains
- In this study, we report that OsHAK26 is preferentially expressed in anthers and seed husks and located in Golgi apparatus
- Connection
- OsHAK1, OsHAK26, Function of Rice HAK Transporters in Pollen Development and Fertility., Knockout of either OsHAK26 or plasma membrane located H+-K+ symporter gene OsHAK1 or OsHAK5 in both Nipponbare and Dongjin cultivars caused distorted anthers, reduced number and germination rate of pollen grains
- OsHAK1, OsHAK26, Function of Rice HAK Transporters in Pollen Development and Fertility., Seed-setting rate assay by reciprocal cross-pollination between the mutants of oshak26, oshak1, oshak5 and their wild types confirmed that each HAK transporter is foremost for pollen viability, seed-setting and grain yield
- OsHAK1, OsHAK26, Function of Rice HAK Transporters in Pollen Development and Fertility., Intriguingly, the pollens of oshak26 showed much thinner wall and were more vulnerable to desiccation than those of oshak1 or oshak5
