Yield increase in plants overexpressing the SHSRP genes

摘要

A transgenic crop plant transformed by a Serine Hydroxymethyltransferase-Like Stress-Related Polypeptide (SHSRP) coding nucleic acid, wherein expression of the nucleic acid sequence in the crop plant results in the plant's increased root growth, and/or increased yield, and/or increased tolerance to environmental stress as compared to a wild type variety of the plant. Also provided are agricultural products, including seeds, produced by the transgenic crop plants. Also provided are isolated novel SHSRPs, and isolated novel nucleic acids encoding SHSRPs, and vectors and transgenic plant containing the same.

主权项

1. A method of increasing root growth in a plant, the method comprising the steps of:
a) designing an expression vector comprising a promoter operatively linked to a polynucleotide encoding a polypeptide comprising SEQ ID NO:2; b) transforming cells of the plant with the vector of step a); c) regenerating transformed plants from the transformed cells of step b); d) determining root growth of the regenerated transformed plants of step c); and e) selecting transgenic plants:
i) which demonstrate increased root growth as compared to a non-transgenic control plant of the same species; andii) which comprise the polynucleotide.
