  • Publication number: 20110196142
    Abstract: DNA molecule for expressing hairpin RNA, the constructing method and the use thereof are provided. The DNA molecule is a closed single-strand cyclic DNA molecule which is constructed by linking four fragments A, B, C and D as following order: A-C-B-D or A-D-B-C, wherein A is a sense strand or anti-sense strand fragment of the target double-strand DNA; B is the fragment which is reversely complementary to A; C and D are DNA fragments with stem-loop structure and they meet one of the following requirements: 1) the nucleotide sequence of fragment C or D comprises at least one sequence e; 2) the nucleotide sequence of fragment C comprises at least one sequence e, the nucleotide sequence of fragment D comprises at least one sequence f, wherein sequences e and f individually are one strand of different restriction endonuclease recognition sequences. The DNA molecule for expressing hairpin RNA and its constructing method are useful in constructing lhRNA library.

  • Publication number: 20080060098
    Abstract: The invention discloses maize bZIP transcriptional factors, namely, ABP2, ABP4 and ABP9, the genes encoding these factors, and the use thereof. The transcriptional factors are proteins having an amino acid sequence set forth in SEQ ID NO: 2, 4, or 6, or proteins derived therefrom by substitution, deletion or addition of one or more amino acid residues of SEQ ID NO: 2, 4, or 6, and having the same activity as a protein shown by SEQ ID NO: 2, 4, or 6. The ABP2, ABP4 and ABP9 genes encoding these factors, respectively, are the DNA sequences having an identity of more than 90% with a sequence shown by SEQ ID NO: 1, 3 or 5 and the encoded proteins having such same functions. These genes are important for breeding plant varieties with an enhanced tolerance to abiotic stresses and for improving plant tolerance to abiotic stresses.
