In the United States, the primary agencies involved in regulating ABA-enhanced crops are the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), and the United States Department of Agriculture (USDA). The EPA is responsible for assessing the environmental impact of these crops, particularly in terms of their potential effects on non-target organisms and ecosystems. The FDA oversees the safety of food products derived from ABA-enhanced crops, while the USDA regulates the cultivation and interstate movement of these plants.

The European Union (EU) has a more stringent regulatory approach to genetically modified organisms (GMOs), which may include some ABA-enhanced crops. The European Food Safety Authority (EFSA) conducts rigorous risk assessments, and approval for cultivation or import requires a majority vote from EU member states. This process has historically been more challenging for biotech crops in Europe compared to other regions.

In many developing countries, regulatory frameworks for ABA-enhanced crops are still evolving. Some nations have adopted systems similar to those in the US or EU, while others are developing their own approaches. International organizations such as the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) provide guidance and support for establishing regulatory frameworks in these countries.

Key considerations in the regulatory process for ABA-enhanced crops include assessing their potential impact on biodiversity, evaluating any unintended effects on non-target species, and ensuring food and feed safety. Regulators also consider the potential for gene flow to wild relatives and the development of resistance in target pests or pathogens.
