The humble mung bean has sustained civilizations for more than 4,500 years during its cultivation across Asia. USC Dornsife researchers discovered a distinct cultivation path, revealing influential factors in the crop’s expansion. Two distinct variants of the crop were identified, each capable of adapting to specific geographic locations: one thrives in short growing seasons and extreme heat, while the other exhibits drought tolerance. These findings offer crop breeders — and the millions of people who rely on this food supply — a future in the face of climate change projections.
