Reports root ion flux measurements and transcriptomics revealing how a salt-tolerant tree seedling reallocates resources to maintain ion balance under salinity stress.
Key Takeaways
- Gleditsia sinensis roots actively exported Na+ and increased H+ influx in the elongation zone under salt stress
- Seedlings down-regulated energy-intensive metabolic pathways to reallocate energy toward defense processes
- Up-regulation of AHA11, AKT1, and SKOR established proton gradients and maintained intracellular K+ homeostasis
