Abstract
A process is described for decreasing organ abscission in plants by modifying the IDA gene, a homologue, fragment, or derivative thereof, or the expression thereof.
Claims17
A method of decreasing organ abscission in a plant, comprising reducing the expression level of a gene in a plant, wherein the gene:
- a) is the IDA gene or a mimetic thereof;
- b) includes a coding sequence for a C terminal motif PpSa/gPSk/rk/rHN;
- c) includes a coding sequence for a N terminal hydrophobic signal peptide;
- d) includes a coding sequence for a C terminal motif v/iPpSa/gPSK/rk/rHN and a coding sequence for an N terminal hydrophobic signal peptide;
- e) is selected from:
- AY087883, AtIDL1, gene At3g25655, tomato (LeIDL1, ac. no AI779570, lotus (LjIDL1, ac. NO. AW719486), soybean (GmIDL1 ac. NO. Bq630646), black locust (RpIDL1, ac. NO. BI642538), maize (ZmIDL1, ac. NO. BI430572), poplar (PtIDL1, ac. NO. BU889756), and wheat (TaIDL1, ac. no BM135459);
- or
- f) is or comprises all or part of the nucleotide sequence presented as any one of SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 8, SEQ ID No. 9, SEQ ID No. 10 or SEQ ID No. 11 or a variant of any thereof or a homologue of any thereof.
A nucleotide sequence wherein the nucleotide sequence is
- a) a modified sequence;
- b) all or part of a sequence selected from:
- AY087883, AtIDL1, geneAt3g25655, tomato (LeIDL1, ac. No. AI779570, lotus (LjIDL1, ac. NO. AW719486), soybean (GmIDL1, ac. NO. Bq630646), black locust (RpIDL1, ac. NO. BI642538), maize (ZmIDL1, ac. NO. BI430572), poplar (PtIDL1, ac. NO. BU889756), and wheat (TaIDL1, ac.no BM135459), a nucleotide sequence that includes a coding sequence for a C terminal motif PpSa/gPSk/rk/rHN, a nucleotide sequence that includes a coding sequence for an N terminal hydrophobic signal peptide, a nucleotide sequence that includes a coding sequence for a C terminal motif v/iPpSa/gPSK/rk/rHN and a coding sequence for an N terminal hydrophobic signal peptide;
- or
- c) all or part of a nucleotide sequence according to b), further comprising one or more mutations in any of said sequence;
- wherein when a plant comprises or is transformed with said nucleotide sequence said plant exhibits decreased organ abscission.
An isolated and/or purified nucleotide sequence, construct, vector, expression vector, transformation vector, or transformed cell comprising all or part of, or which can hybridise to or is complementary to, the nucleotide sequence presented as SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 8, SEQ ID No. 9, SEQ ID No. 10 or SEQ ID No. 11, or an isolated amino acid sequence comprising the sequence as shown in SEQ ID No. 3 or a sequence substantially homologous thereto, or a fragment thereof.
