| Helianthus annuus | betaine aldehyde dehydrogenase transcript levels and activity are differentially modulated by NO in light and dark growth conditions. The extent of the impact of NO on GB content and BADH activity also varies with light exposure, but the pattern observed is similar to that observed in dark-grown seedlings. Betaine aldehyde dehydrogenase transcript levels and activity are differentially modulated by NO in light and dark growth conditions | additional information |

| metabolism | NO's involvement in the biosynthetic pathway of GB production in plants takes place prior to the involvement of BADH in converting the toxic intermediate betaine aldehyde to GB. The extent of the impact of NO on GB content and BADH activity also varies with light exposure, but the pattern observed is similar to that observed in dark-grown seedlings | Helianthus annuus |
| physiological function | nitric oxide and light co-regulate glycine betaine (GB) homeostasis in sunflower seedling cotyledons by modulating betaine aldehyde dehydrogenase transcript levels and activity. A reasonable amount of GB is being constitutively synthesized in sunflower seedling cotyledons. Sensing of NaCl stress, however, enhances the GB concentration by several folds. Analysis of GB accumulation at three different growth stages of seedling cotyledons (2, 4, and 6 days old) shows that accumulation is age dependent. NaCl stress and availability of NO regulate BADH activity and, therefore, accumulation of GB | Helianthus annuus |
