Application of the GmRD22 Gene and Its Product from Soybean to Enhance Tolerance toward Salinity and Drought Stresses in Plants

Summary

Salinity and drought stresses posed a severe problem to agriculture worldwide. Both stresses will lead to physiological drought and cause damage to plant cells, resulting in retarded plant growth and consequently a reduction in crop yield. We cloned and characterized the GmRD22 gene from soybean. This gene is induced by both salt and drought treatment. Expression of this gene in transgenic rice can improve salinity and drought tolerance. Transgenic rice expression this gene could tolerate salt up to 2%. Therefore, this novel class of seed maturation protein gene and their gene products can be used to improve salt and drought tolerance in plants, cell cutures, and cell lines.

Title: Use of GmRD22-like genes to protect against abiotic stress
Usefulness: Use of GmRD22-like genes to protect against abiotic stress
Summary: The polypeptide, polynucleotide, or recombinant nucleic acid construct is useful in water saving agricultural practice, by applying water-saving cultivation methods to a plant. The polypeptide is useful for protecting a plant from abiotic stress, and for selecting successfully transformed plant cells or plants. The abiotic stress is selected from salinity stress, drought, and/or dehydration (all claimed).
Novelty: New substantially pure GmRD22 polypeptide and polynucleotide, useful for protecting a plant from abiotic stress, e.g. salinity stress, drought, and/or dehydration
