Application of pectin synthetase gene BnGATL10

The invention discloses application of a pectin synthetase gene BnGATL10, and belongs to the field of plant genetic engineering. The nucleotide sequence of the pectin synthetase gene BnGATL10 is as shown in SEQ ID NO.3, and the sequence of protein coded by the pectin synthetase gene BnGATL10 is as shown in SEQ ID NO.4. According to the invention, a recombinant vector comprising the gene is constructed, the recombinant vector is transformed into rape by an agrobacterium infection method to obtain a transgenic plant, the expression quantity of the BnGATL10 in brassica napus is improved by a genetic engineering technology, the leaf sclerotinia sclerotiorum lesion area of the transgenic rape can be reduced by 47.39%, and the plant is more resistant to sclerotinia sclerotiorum, so that the leaf sclerotinia sclerotiorum lesion area can be reduced by 47.39%. The method has an important application prospect in enhancing the sclerotiniose resistance of the brassica napus. 本发明公开了一种果胶合成酶基因BnGATL10的应用，属于植物基因工程领域。所述果胶合成酶基
