- Key message
- OsCAX1a mRNA was induced in roots by high concentrations of Ca(2+)
- These results suggest that OsCAX1a transports Ca(2+) into vacuoles and is involved in Ca(2+) homeostasis in cells that suffer from high concentrations of Ca(2+)
- Furthermore, transgenic rice plants transformed with the OsCAX1a promoter fused to beta-glucuronidase showed reporter expression in vascular bundles, stomata, trichomes, steles, flowers, embryos and aleurone layers
- In the case of stomata and trichomes, transcription of OsCAX1a was particularly high in aged organs
- Following, the panicle degeneration gene OsCAX1a was identified in the mutant, which was involved in Ca(2+) transport
- Our results explained the key role of OsCAX1a in Ca(2+) transport and distribution and laid a foundation to further explore the genetic and molecular mechanisms of panicle degeneration in rice
