Abstract
The present invention relates to an isolated polynucleotide capable of giving a plant tolerance to drought and/or salt stress, which comprises a polynucleotide sequence as shown in SEQ ID NO:1, and to a promoter capable of giving a plant tolerance to drought and/or salt stress. The present invention also relates to an expression vector comprising the said polynucleotide and/or the said promoter, and to a host cell transformed or transfected by the said expression vector. The present invention further relates to a use of the said polynucleotide or promoter sequence in improvement of plant tolerance to drought and/or salt stress.
Claims10
An isolated polynucleotide capable of giving a plant tolerance to drought and/or salt stress, which comprises a nucleotide sequence as shown in SEQ ID NO:1, or a conservative variant or degenerate sequence comprising one or more substitutions, deletions, additions and/or insertions in the said nucleotide sequence, or a sequence hybridizable with the said sequence under moderate stringent condition, or a complementary sequence thereof, or a variant or derivative having at least 95% homology and same or similar biological function to the said nucleotide sequence.
A promoter capable of giving a plant tolerance to drought and/or salt stress, which comprises a nucleotide sequence as shown in the DNA sequence of the positions 1-1373 of SEQ ID NO:1, or a conservative variant or degenerate sequence comprising one or more substitutions, deletions, additions and/or insertions into the said nucleotide sequence, or a sequence hybridizable with the said sequence under moderate stringent condition, or a complementary sequence thereof, or a variant or derivative having at least 95% homology and same or similar biological function to the said nucleotide sequence.
