FIELD: agriculture.SUBSTANCE: invention relates to a method of weed destruction, providing the step of applying the herbicide of PPO-inhibitory type on the cultivated part of the plant, where the said plant is resistant to the said herbicide and expresses the protein with the ability to convert the said herbicide into the herbicide with lower herbicidal activity. The method of evaluation of resistance of the plant cell or the plant to herbicide of PPO-inhibitory type is disclosed, comprising bringing into contact of the herbicide of PPO-inhibitory type with the plant cell or the plant into which DNA is introduced and expressed, which encodes the protein capable to convert the said herbicide into the herbicide with lower herbicidal activity, and also the method of intake of plant cell or plant resistant to the herbicide of PPO-inhibitory type, providing the step of intake of the plant cell or plant based on the aforesaid method for evaluating the stability. Also the plant cell, the plant, the cell culture of plant are disclosed, resistant to herbicide of PPO-inhibitory type, as well as the method of treating the herbicide of PPO-inhibitory type and use of the protein or DNA encoding the said protein for treatment of herbicide of PPO-inhibitory type, where the protein is capable to convert the aforesaid herbicide into the herbicide with lower herbicidal activity.EFFECT: invention enables to destroy selectively only the weeds on the cultivated part of the plant.10 cl, 66 dwg, 35 tbl, 75 exИзобретение относится к области биохимии, в частности к способу уничтожения сорняков, предусматривающему стадию нанесения гербицида РРО-ингибиторного типа на культивируемую часть растения, где указанное растение обладает устойчивостью к указанному гербициду и экспрессирует белок со способностью превращать вышеуказанный гербицид в гербицид с более низкой гербицидной активностью. Раскрыт способ оценки резистентности клетки растения или растения к гербициду РРО-ингибиторного типа, включа
