  • Activation of the arabidopsis hypertall (HYT1/YUCCA6) locus affects several auxin mediated responses
    Patent number: 7763772
    Abstract: The present invention provides nucleotide sequences and a corresponding amino acid sequence of auxin overproduction mutants. Also provided are methods to improve plant growth, development, differentiation, increased tolerance to drought and delayed senescence as well as plants with drought tolerance and delayed senescence.
    Type: Grant

  • SOS1 gene from that confers salt tolerance
    Patent number: 7238865
    Abstract: An SOS gene has been isolated through PCR cloning from Thellungiella halophila and is designated TSOS1. The polynucleotide encodes a transmembrane protein with similarities to plasma membrane Na+/H+ antiporters from bacteria and fungi. The invention encompasses the TSOS1 gene, the corresponding protein, closely related polypeptides that confer salt tolerance, and related polynucleotides that encode a polypeptide that has Na+/H+ antiporter activity.

  • Methods and compositions for regulating plant stress tolerance
    Patent number: 7186563
    Abstract: Methods and compositions relate to improving stress tolerance in plants including cold tolerance. HOS9 is a homeobox transcription factor that controls stress tolerance in plants by modulating the activity of a number of cold-responsive genes. Transgenic plant, cell, seed and expression vectors that include a molecule having a nucleic acid sequence derived from HOS9 confer or improve cold tolerance.

  • Osmotin gene promoter and use thereof
    Patent number: 5874626
    Abstract: Described are an isolated DNA fragment incorporating an osmotin gene promoter sequence, recombinant DNA incorporating a foreign structural gene under control of an osmotin gene promoter sequence, as well as methods and transformants involving the isolated DNA fragment and recombinant DNA. Also described are methods for the inhibition of fungal, insect, nematode, and viral pathogens in a plant using such recombinant DNA.
