    • The present invention relates to nucleic acid molecules corresponding to regulatory portions of genes whose expression is predominant in cambium and/or xylem. The invention also relates to compositions and methods of using the same to regulate the expression, in a cambium/xylem-preferred manner, of genes and/or any kind of nucleotide sequences in a plant. Nucleic acid molecules and its compositions include novel nucleotide sequences for cambium/xylem-preferred promoters identified and isolated from poplar (Populus spp). Methods for expressing genes and/or any kind of nucleotide sequences in a plant using the promoter sequences disclosed herein are provided. The methods comprise stably incorporating into the genome of a plant cell in a nucleotide sequence operably linked to a cambium/xylem-preferred promoter of the present invention and regenerating a stably transformed plant that expresses the nucleotide sequence.
    • 本发明涉及对应于在形成层和/或木质部中表达占优势的基因调控部分的核酸分子。 本发明还涉及组合物和使用它们调节植物中基因和/或任何种类的核苷酸序列形式(以形成层/木质部优选的方式)的组合物和方法。 核酸分子及其组合物包括从杨树(Populus spp)鉴定和分离的形成层/木质部优选启动子的新核苷酸序列。 提供了使用本文公开的启动子序列在植物中表达基因和/或任何种类的核苷酸序列的方法。 所述方法包括在与本发明的形成层/木质部优选的启动子有效连接的核苷酸序列中稳定地并入植物细胞的基因组中并再生表达该核苷酸序列的稳定转化的植物。
