Development and Breeding of Herbicide‐Resistant Sorghum for Effective Cereal‐Legume Intercropping

open access: yesAdvanced Science, EarlyView.
This study identified two SbALS mutations (A93T and S624N) conferring robust herbicide resistance in sorghum, facilitating efficient weed control. Structural analysis revealed that imazamox resistance is mediated by disrupted herbicide binding. Furthermore, 126 imazamox resistant soybean varieties are screened for sorghum‐soybean intercropping ...
