A chitin- and jasmonate-inducible Arabidopsis lectin gene and a method for the generation of disease-resistant transgenic plants by transforming the gene

摘要

A method for preparing a plant with increased disease-resistance is provided to obtain a plant having high resistance against pathogenic fungi by transforming a lectin gene AtMJI2 derived from Arabidopsis thaliana and expressed by chitin and jasmonate, thereby significantly decreasing the loss induced by the infection of blight and harmful insects. A method for increasing the disease resistance of a plant comprises a step of transforming a recombinant plant expression vector including a lectin gene AtMJI2 derived from Arabidopsis thaliana to a plant, wherein the vector is pCaAtMJ12 depicted in Fig. 4. An Arabidopsis thaliana prepared by the method is characterized in that it has the increased disease resistance.
