Promoter P delta OsVSP1 for specific expression of mesophyll cells of plant leaves and application of promoter P delta OsVSP1

The invention discloses a plant leaf mesophyll cell specific expression promoter P delta OsVSP1 and application thereof, and belongs to the field of plant molecular biology. The promoter P [delta] OsVSP1 is the following 1) or 2) or 3): 1) a DNA fragment as shown in SEQ ID No.1; 2) a DNA fragment which has more than 99%, more than 95%, more than 90%, more than 85% or more than 80% of homology with the nucleotide sequence limited by 1) and has a promoter function; and 3) a DNA fragment which is hybridized with the nucleotide sequence limited by 1) or 2) under strict conditions and has a promoter function. Experiments prove that the promoter P delta OsFS1 disclosed by the invention can effectively promote specific expression of a target gene in leaf mesophyll cells, so that adverse effects caused by continuous expression of an exogenous gene in other tissues of a plant are effectively avoided. 本发明公开了植物叶片叶肉细胞特异性表达的启动子PΔOsVSP1及其应用，属于植物分子生物学领域。启动子PΔOsVSP1为如下1)或2)或3)：1)SEQ ID No.1所示DNA片段；2)与1)限定的核苷酸序列具有99％以上、95％以上、
