Claim 1: Nucleic Acid, which is a sequence of nucleic acids, selected from the group consisting of (a) a Nucleic Acid Sequence according to the SEQ ID no. 29, 3,7, 11, 15, 25, 35, or a functional fragment thereof, (b) a Nucleic Acid Sequence that is complementary to a Sequence)(c) a Nucleic Acid Sequence that is at least 80% identical to a sequence of (a) or (b)(d) a Nucleic Acid Sequence according to the genetic code is degenerate is derived from a sequence of nucleic acids under (a), (b) or (c)(e) a sequence of nucleic acid Hybrid with a sequence of nucleic acids under (a), (b) or (c) under rigorous conditions,(f) a Nucleic Acid Sequence encoding a Protein of Agreement with the SEQ ID no. 30, 4, 8, 12, 16 or 26 or an ortholog Counterpart, or Analogue thereof,(g) a Nucleic Acid Sequence encoding one or more RNAs that can at least partially hybridize with themselves or between themselves and thus form a double Strand.Where this sequence of nucleic acids is consistent in at least 19 consecutive nucleotides in a Nucleic Acid sequences selected from the group consisting of: (i) a sequence ofNucleic Acids according to the SEQ ID no. 27, 17, 19, 5, 7, 23 or 25, (ii) a Nucleic Acid Sequence that is complementary to a sequence of (i),(iii) a Nucleic Acid Sequence that is at least 80% identical to a sequence of (i) or (ii)(iv) a Nucleic Acid Sequence according to the genetic code is degenerate is derived from a sequence of nucleic acids under (i), (ii) or (iii)(V) a sequence of nucleic acid Hybrid with a sequence of nucleic acids under (i), (ii) or (iii) under rigorous conditions,(VI) a Nucleic Acid Sequence encoding a Protein of Agreement with the SEQ ID no. 28, 18, 20, 6, 8, 24 or 26, or an Analogue or ortholog Counterpart, thereof,(vii) or a sequence of nucleic acids in antisense orientation with respect to a sequence of nucleic acids under (i) to (VI).Claim 2: procedure for the production of a Plant tolerant to low temperatureThat includes the following steps: a) mutage
