玉米组织特异性启动子及其应用
摘要：
本发明公开了玉米组织特异性启动子及其应用，属于植物组织特异性启动子的分离和应用领域。本发明首先公开了从玉米中分离的核苷酸序列为SEQ ID NO.1所示的组织特异性启动子，本发明将该组织特异性启动子序列进一步截短后获得仍具有启动子功能的SEQ ID NO.2或SEQ ID NO.3所示的截短的启动子片段。本发明进一步公开了所述组织特异性启动子或截短后的启动子片段在提高作物种子品质、改良作物性状以及培育转基因植物新品种等方面的应用。
摘要（英）：

The invention discloses a corn tissue specificity promoter and applications thereof, and belongs to the field of separation and applications of plant tissue specificity promoters. The invention firstly discloses the tissue specificity promoter as shown by nucleotide sequence SEQ ID NO.1 separated from corn, and the tissue specificity promoter sequence is further truncated to obtain a truncated promoter segment as shown by SEQ ID NO.2 or SEQ ID NO.3 still with the promoter function. The invention further discloses the applications of the tissue specificity promoter or the truncated promoter segment in aspects of enhancing crop seed quality, improving crop characters and cultivating new varieties of transgenic plants and the like.
