“…Stressors can trigger the synthesis and release of catecholamines in plants. These compounds help plants cope with stress by controlling numerous physiological progressions, counting development, growth, and defense mechanisms. − Many studies have found that dopamine levels vary widely from a few nanograms to many micrograms, depending on the species . It has been determined that each plant organ of 44 different plant species possesses substantial amounts of catecholamines, 29 of which are typically found in human diets. − Environmental factors impact the creation of catecholamines in addition to the variations in their biosynthesis pathways in plants.…”

Dopamine, alongside norepinephrine and epinephrine, belongs to the catecholamine group, widely distributed across both plant and animal kingdoms. In mammals, these compounds serve as neurotransmitters with roles in glycogen mobilization. In plants, their synthesis is modulated in response to stress conditions aiding plant survival by emitting these chemicals, especially dopamine that relieves their resilience against stress caused by both abiotic and biotic factors. In present studies, there is a lack of robust methods to monitor the operations of dopamine under stress conditions or any adverse situations across the plant's developmental stages from cell to cell. In our study, we have introduced a groundbreaking approach to track dopamine generation and activity in various metabolic pathways by using the simple nitrogen and sulfur co-doped carbon quantum dots (N, S-CQDs). These CQDs exhibit dominant biocompatibility, negligible toxicity, and environmentally friendly characteristics using a quenching process for fluorometric dopamine detection. This innovative nanomarker can detect even small amounts of dopamine within plant cells, providing insights into plant responses to strain and anxiety. Confocal microscopy has been used to corroborate this occurrence and to provide visual proof of the process of binding dopamine with these N, S-CQDs inside the cells.
