Women manage the vast majority of the world's horticultural resources, particularly in tropical regions with a high concentration of plant species. They are the go-to people for managing precious plants, both cultivated and wild, in their respective environments. Women's regular work has always necessitated expanding their knowledge. Wild plant collectors, home gardeners, plant domesticators, herbalists, and seed keepers all overwhelmingly tend to be women. In many parts of the globe and among many different cultural groupings, they have informal monopolies on plant breeding and farming. The primary values (use and cultural values) of plant genetic resources are localised and non-monetary, making them mostly invisible to outsiders and easily depreciated. This study explores the ways in which sexism in the scientific community hinders our understanding of the plant kingdom and, by extension, our capacity to influence that realm in accordance with human values.
