Plant Signaling
If you grow eggplant or other nightshades and your neighbors spray pesticides that drift into your garden, natural compounds already present in plants could be used as a protective treatment to help your vegetables recover.
Chlorpyrifos is a common pesticide that, even when it drifts onto plants unintentionally, can seriously harm eggplant growth and its ability to photosynthesize. Scientists tested two natural signaling substances — GABA (found in many living things) and nitric oxide — and found that applying them together gave eggplants a much stronger defense against pesticide damage than either one alone. The combination helped restore nearly normal growth, leaf pigmentation, and the plant's internal antioxidant defenses.
Key Findings
Chlorpyrifos stress reduced eggplant biomass by 48%, chlorophyll a by 35%, and photosynthetic performance index by 52%
Combined GABA + nitric oxide treatment outperformed either compound applied alone in restoring growth, pigmentation, and photosynthetic function
The GABA + nitric oxide combination helped maintain redox balance by boosting the plant's own antioxidant system, reducing oxidative damage from pesticide exposure
chevron_right Technical Summary
Researchers found that applying GABA and nitric oxide together to eggplant seedlings significantly counteracted the growth and photosynthesis damage caused by chlorpyrifos pesticide exposure, offering a natural, chemical-free way to protect crops from pesticide stress.

Eggplant, aubergine, brinjal, or baigan is a plant species in the nightshade family Solanaceae. Solanum melongena is grown worldwide for its edible fruit, typically used as a vegetable in cooking.
