FIELD: biochemistry.
SUBSTANCE: invention relates to a recombinant DNA molecule encoding a protein having the activity of herbicide-tolerant protoporphyrinogen oxidase. Also a DNA construct containing the specified DNA molecule; an engineered protein that encodes the specified DNA molecule; transgenic plant, seed, plant cell, plant part, containing the specified DNA molecule are disclosed. The methods for imparting PPO herbicide tolerance to a plant and preventing weed growth using the said DNA molecule; a method of obtaining a plant containing the specified DNA molecule; methods for identifying and screening the said DNA molecule; a method for reducing the occurrence of herbicide-tolerant weeds and imparting PPO-herbicide tolerance to a seed, plant cell, and plant part are disclosed.
EFFECT: invention makes it possible to effectively impart PPO-herbicide tolerance.
