| 摘要 |
A polynucleotide including a gibberellin 20 oxidase gene and a promoter, more specifically a vascular specific promoter that includes one of (a) a nucleotide sequence of SEQ ID No. 2; (b) a nucleotide sequence of substantial sequence similarity to SEQ ID No. 2; (c) a nucleotide sequence that complements or is able to hybridize to (a) or (b); and (d) a nucleotide sequence which is the reverse complement of (a), (b), or (c). The gibberellin 20 oxidase gene includes one of (1) a nucleotide sequence listed in SEQ ID No. 1 as shown in FIG. 2, a fragment, domain, or feature thereof; (2) a nucleotide sequence of substantial sequence similarity to SEQ ID No. 1; (3) a nucleotide sequence that complements or is able to hybridize to (1) or (2); and (4) a nucleotide sequence which is the reverse complement of (1), (2), or (3). A vector and a transgenic plant that include the gibberellin 20 oxidase gene and the promoter are also provided by the present disclosure. Processes for generating the transgenic plant and for accelerating plant growth and/or increasing cellulose yield are also provided by various embodiments of the present disclosure.
