BoMF9c and BoMF9l genes, homologous to the BcMF9 gene encoding pollen-specific polygalacturonase of Chinese cabbage,were cloned from Brassica oleracea var. capitata and B. oleracea var. alboglabra by PCR amplification.

• 根据白菜花粉特异的多聚半乳糖醛酸酶基因BcMF9的全长序列设计引物；通过PCR直接扩增的方法从结球甘蓝(Brassica oleracea var.；capitata)和芥蓝(B
