Provide ingredients and methods to make herbicides resistant to bacteria.Botany,Cells,Plant tissues and seeds Components include polynucleotides, which encode herbicide-resistant polypeptides.Including these polynucleotide delivery vehicles and host cells containing delivery vehicles. Nucleotide sequences can be used to make DNA or expression bands for transformation and expression of organisms.It includes microorganisms and plants. The composition also includes bacteria.Botany,Cells,Plant tissue and seed transformation. Especially,The isolated polynucleotides can encode polypeptide resistance for Hppd inhibitors. In addition,Amino acid sequences corresponding to polynucleotides are provided. 1. Characteristic 1: A recombinant nucleic acid molecule, consisting of a series of nucleic acids, encodes the enzyme 4-hydroxyphenylpyridine dihydrogenase (HppD).The nucleoside sequence encodes the amino acid sequence as SEQ number 1 at least 55%.Or fragments of thisThe amino acid sequence selected from this group includes: (1) amino acid sequence, and its amino acid substitutes are: (a) leukemia in amino acid position, which is equivalent to the amino acid position in SEQ ID No.1；(b) Aspirinic acid at the amino acid position corresponds to amino acid 268 in SEQ 1；(c) Alachlor in amino acid, corresponding to amino acid 270 in SEQ 1；(d) Prolina at the amino acid position is equivalent to 335 in SEQ 1；(e) The position of the amino acid of aspirin is equivalent to the amino acid 336 in SEQ phase 1.(f) Serina of amino acid location, equivalent to the position of amino acid 337 in SEQ 1；(g) The thyroid gland at the amino acid location corresponds to the amino acid 339 in SEQ ID No.1；(h) Argon at the amino acid position is equivalent to 340 amino acids in SEQ Directive 1；(i) Glutamic acid in the amino acid position, which corresponds to amino acid 344 in SEQ 1；Y(j) A methaquinone at the amino acid site, which corresponds to the position of amino acid 345 in the first issue of Chemic
