1-11. (canceled)
A method for selecting a plant having improved early vigor during germination relative to a control plant, comprising:
- a) inducing expression or increasing expression in a plant, a polynucleotide sharing at least 70% identity with a polynucleotide selected from the group consisting of:
- SEQ ID NO:
- 4 (OsTPPT);
- SEQ ID NO:
- 7 (OsTPPT);
- SEQ ID NO:8 (OsTPPT);
- and SEQ ID NO:
- 9 (OsTPPT), wherein the induced or increased expression of the polynucleotide is obtained by transforming and expressing in the plant the polynucleotide;
- and
- b) selecting a plant having improved early vigor during germination relative to a control plant.
16-17. (canceled)
19-52. (canceled)
A method of improving plant tolerance to anaerobic germination, the method comprising introducing into a rice plant, being susceptible to anaerobic germination (AG), a nucleic acid sequence that encodes a functional trehalose-6-phosphate phosphatase (TPP), thereby improving tolerance of the plant to anaerobic germination.
A plant or part thereof having a deletion in endogenous TPP and comprising an exogenous nucleic acid sequence encoding a functional TPP, said plant exhibiting tolerance to AG.
