Plant vitamin B homeostasis for human and plant health. Vitamin B homeostasis of plants is essential for plant health and is also important for human health because plants serve as a primary vitamin B source for humans. State‐of‐the‐art engineering approaches and agricultural practices, as well as the exploration of natural varieties of food crops and edible plants, may provide plant‐based food sources with enhanced and balanced B vitamin content to support plant and human health. Developments in analytical technologies could provide a more precise diagnosis of vitamin B status in plants and humans, which will in turn improve our understanding of the regulation of B vitamin metabolism and assist in providing vitamin B‐rich sources in the right proportions.
