additional information | there are no significant changes in the physiological or chlorophyll fluorescence parameters between tomato leaves of wild-type and transgenic GSNOR overexpressing lines under control conditions. In contrast, apparent chlorosis is observed in the wild-type lines after 20 d under Fe-deficiency conditions, while transgenic lines show significantly higher Fe-deficiency tolerance levels than wild-type lines as assessed by morphological characteristics, especially the color of the stem apices and new leaves | Solanum lycopersicum |

Fe2+ | GSNOR expression is induced by Fe deficiency in tomato leaves and roots, while its overexpression alleviates chlorosis under Fe-deficiency conditions. GSNOR overexpression positively regulates the Fe distribution from root to shoot, which might result from the transcriptional regulation of genes involved in Fe metabolism | Solanum lycopersicum | |

malfunction | overexpression alleviates chlorosis under Fe-deficiency conditions. GSNOR overexpression positively regulates the Fe distribution from root to shoot, which might result from the transcriptional regulation of genes involved in Fe metabolism. Overexpression of GSNOR maintains redox homeostasis and protects chloroplasts from Fe deficiency-related damage, resulting in a greater photosynthetic capacity. As a nitric oxide regulator, GSNOR's overexpression decreases the excessive accumulation of nitric oxide and S-nitrosothiols during the Fe deficiency, and maintains the homeostases of reactive oxygen species and reactive nitrogen species. Moreover, GSNOR overexpression, probably at the level of genes and proteins, along with protein S-nitrosylation, promotes Fe uptake and regulates the shoot/root Fe ratio under Fe-deficiency conditions. The overexpression of GSNOR alleviates the Fe-deficiency-induced oxidative stress | Solanum lycopersicum |
physiological function | enzyme GSNOR is a nitric oxide regulator and is involved in responses to iron deficiency, GSNOR-regulated RNS homeostasis under Fe-deficiency conditions, overview. Ferric-chelate reductase activity is regulated by GSNOR | Solanum lycopersicum |
