While growing in the field, plants may encounter several different forms of abiotic stress simultaneously, rather than a single stress. In this study, we investigated the effects of calcium (Ca) deficiency on cadmium (Cd) toxicity in rice seedlings. Calcium deficiency alone decreased the length, fresh and dry weight, and the Ca concentration in shoots and roots.

- Glutathione reductase (GR) plays a key role in protecting rice plants from oxidative stress, and this study focused on how NaCl affects the expression of GR genes in rice roots.
- The researchers found that the expression of specific isoforms of the GR genes (OsGR2 and OsGR3) increased with NaCl treatment, while another isoform (OsGR1) did not show this response, indicating that sodium ions (Na+) are critical for this induction.
- Their results suggest that the increase in GR activity and hydrogen peroxide production in rice roots from NaCl isn't due to osmotic stress but directly linked to the presence of Na+.
