This body of knowledge includes information about the biological, ecological, and cultural contexts in which plants are utilized. Traditional ecological knowledge, when merged with bioinformatics, allows for the development of new methodologies to analyze and validate this knowledge.

Biocultural Conservation

The concept of biocultural conservation emphasizes the interconnectedness of biodiversity and cultural diversity. This theoretical framework provides a crucial foundation for using bioinformatics tools to study traditional plant use in various cultures. By preserving both biological and cultural diversity, researchers can employ bioinformatics to document plant species' genetic and ecological attributes alongside their cultural significance in communities.

Systems Biology

Systems biology is an integrated approach that considers biological systems as a whole, rather than in isolation. This field provides the theoretical underpinning for many bioinformatics applications in ethnobotany. By employing systems biology principles, researchers can analyze the complex interactions between various biological pathways, environmental factors, and cultural factors influencing plant usage. Such analyses can be vital in understanding how traditional knowledge can inform modern scientific inquiries.
