Abstract: The present invention relates to the use of a compound, a salt or solvate thereof as C4 plant selective herbicide wherein said compound comprises a cyclic alkyl, aryl, heterocycloalkyl or heteroaryl group, and wherein said compound further comprises a) at least a functional group Z being —C(?Yz)R1, wherein Yz is selected from the group consisting of O, NH and S, preferably wherein Yz is O, and wherein R1 is selected from the group consisting of H, OH and N(R2R3), —O(R2) and —S(R2), wherein R2 and R3, are independently of each other, selected from the group consisting of H, alkyl, cycolalkyl, aryl and heteroaryl and a functional group Q which is —C(?YQ)R4, wherein YQ is selected from the group consisting of O, NH and S, preferably wherein YQ is O, and wherein R4 is selected from the group consisting of H, OH and NR4#R5#, OR4#, SR4# wherein R4# and R5#, are independently of each other, selected from the group consisting of H, alkyl, cycloalkyl, aryl and heteroaryl, or b) at least one electron donating group sel

Abstract: A vector according to the invention with a positive selection possibility for cloning a DNA sequence into a host cell transformed with the vector, wherein the vector contains suitable restriction cleavage sites within a selection gene the functional expression of which is prevented by insertion of the foreign gene is characterized in that it contains a modified cap gene as the selection gene which codes for a CAP protein with modified DNA binding specificity the expression of which is lethal for adenylate-cyclase-positive host cells.
