The role of halopriming in alleviating the detrimental effects of salinity and combined salinity-submergence was evaluated using two rice genotypes, "IR06F148" (anaerobic germination + submergence tolerant [Sub1]) and "Salt-star" (salt tolerant) with contrasting levels of tolerance. Nonprimed seeds and those primed with 1% calcium chloride (CaCl) were germinated, and the seedlings were exposed to salinity (50 or 100 mM sodium chloride [NaCl]) and submergence (nonsaline or saline water). Salinity substantially inhibited plant height, shoot/root dry mass, and leaf area.

- The study investigates how hypoxia-tolerant and -sensitive plant species differ in oxygen diffusion from shoots to roots, focusing on how they adapt to waterlogged conditions.
- Job's tears (tolerant) and sorghum (sensitive) were compared using a special microneedle sensor to measure oxygen levels in various plant parts after being exposed to low-oxygen conditions.
- Results showed that sorghum had significantly lower oxygen levels at the roots compared to Job's tears, which had adaptations to prevent oxygen loss, especially evident in the structure of their root systems.
