Multi-omics dissection of CO₂-induced metabolic reprogramming in broccoli: key regulators of growth and nutritional quality.

ABSTRACT: The rising global CO₂ level influences plant growth, productivity, and nutritional quality, and elevated CO₂ (ECO₂) is commonly utilized in greenhouses to enhance vegetable crop yields. However, the molecular mechanism underlying plant responses to ECO₂ remains unclear. This study examined the impacts of ECO₂ on the nutritional quality and growth characteristics of two widely cultivated broccoli varieties, 'Yanxiu' and 'Qiuli'. A pot experiment was carried out in environmentally auto-controlled growth chambers over a period of 100 days, under both ambient CO₂ (ACO₂, 420/470 ppm, daytime/nighttime) and ECO₂ (700/750 ppm) conditions. Our results demonstrated that ECO₂ significantly enhanced pho
