Molecular Breeding of Chinese Cabbage (Brassica Campestris L.) for Insect Resistance and the Bar Gene Introgression Via Pollination in Cruciferae Plants
Pieris rapae L. and Plutella xylostella L, belong to Lepidoptera, are the main pest disserve Chinese cabbage vegetables. Aiming at the increasing of pest resistance, genetic engineering using insecticidal protein gene were carried out in Chinese cabbage (Brassica campestris L. ssp. pekinensis and B.campestris L.ssp.chinensis ). Meanwhile to assay the safety of the transgenic plants, bar gene transferred to the plants was used as the marker gene to study the foreign gene introgression possibility ...
