Polynucleotides and Methods for obtaining plants resistant to fungal Pathogens

摘要

Polynucleotide sequences that encode genes that may Confer resistance to the plant pathogen, which causes Anthracnose, Colletotrichum, Stalk Rot, Leaf Blight and degeneration of the outbreaks in maize and other cereals.In addition, plants and Seeds of Plants containing Chimeric genes comprising Said polynucleotides sequence, that increase or Confer resistance to plant pathogen Colletotrichum, and processes for obtaining such plants and Seeds.Also sequences that can be used as molecular markers, which in turn can be used to identify the region of interest in Maize lines that are the result of crossbreeding New to enter quickly and effectively to the genes of maize lines containing dich I genes in other Maize lines that do not contain these genesIn order to make them resistant to Colletotrichum and resistant to Stalk rot. Claim 1: an isolated polynucleotide comprising a polynucleotide selected from the group consisting of: (a) a Nucleotide sequence that encodes a polypeptide capable of conferring or improve.Resistance to Colletotrichum coexpresa when in a Second floor with a Nucleotide sequence that encodes the SEQ ID no: 3, where the polypeptide has an amino acid sequence of at least 75% Identity when compared to SEQ ID no: 246 based on the algorithm of Aline Ation of Needleman Wunsch; (b) a complementary Nucleotide sequence (a)Where the Supplement and the sequence of nucleotides consist of the same number of Nucleotides and are 100% complementary; and (c) a Nucleotide sequence that encodes a polypeptide that confers Enhanced resistance to Colletotrichum, when coexpresa in a plant with a Second STRI ng + Garter Set CLA of nucleotides that encodes the SEQ ID no: 3,Where the polypeptide has an amino acid sequence of at least 75% Identity when compared with the sequence of the Plasmid Deposited with no Patents 50050 NRRL B - based on the Needleman Wunsch alignment algorithm.
