NEW nucleic acid sequences and their use in a way to achieve pathogen resistance in plants

摘要

1. A method for increasing the resistance to penetrating through mezofillovye cells pathogens in a plant or in the organ, tissue or cell, wherein the activity of callose synthase in a plant or in the organ, tissue or cell is reduced compared to control rasteniyami.2. A method according to claim 1, characterized in that the pathogens selected from the families comprising Pucciniaceae, Mycosphaerellaceae and Hypocreaceae.3. A method according to claim 1, characterized in that the lower the protein activity of callose synthase comprising the sequences shown in SEQ ID No: 2, 4, 6, 8, 10, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33 or 35 or a protein having at least 40% homology to posledovatelnostyam.4 data. A method according to claim 1, characterized in that available in the plant, plant organ, tissue or cell activity of callose synthase is reduced so that the reduced activity of at least one polypeptide which is encoded by a nucleic acid molecule comprising at least one nucleic acid molecule from the group consisting of: a) nucleic acid molecule encoding a polypeptide comprising presented in SEQ ID No: 2, 4, 6, 8, 10, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33 or 35 sequence; b) nucleic acid molecule which comprises, at least one polynucleotide sequence shown in SEQ ID No: 1, 3, 5, 7, 9, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32 or 34; c) a nucleic acid molecule encoding a polypeptide whose sequence has at least 40% identity to the sequences SEQ ID No: 2, 4, 6, 8, 10, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33 or 35; d) a nucleic acid molecule of (a) to (c), which encodes a fragment or an epitope sequences according to SEQ. ID No .: 2, 4, 6, 8, 10, 11, 13, 1
