    摘要： The objective of this invention is to enhance the efficiency of plastid transformation using nuclear transformed plants in which the microbial recombinase A(recA) is to target to (or expressed in) the plastid. This invention will be better explained by the following detailed descriptions. A plant is transformed with a nuclear transformation vector containing the microbial recA gene added with a plastid targeting sequence. In this nuclear transformed plant, the frequency of plastid transformation is enhanced greater than two-folds due to increased homologous recombination between the plastid transformation vector carrying genes of interest (or target genes) and the plastid genome. In addition, because plastid transformation is accomplished through a gradual process, adventitious shoots selected after being subjected to plastid transformation should be cut into explants, and then shoots regenerated from the explants are to be reselected until all of the plastids in the shoots are uniformly transformed. However, when the nuclear transformed plant is used, the number of reselection is reduced to ½ to ⅓ due to increased homologous recombination.

    摘要： The present invention provides a novel receptor kinase and the gene thereof which can be used for activating plant defense systems against several pathogens such as fungi. The receptor kinase CHRK1 of this present invention has an extracellular domain similar to a chitinase, and whose gene expression is stimulated by infection of TMV. In addition, the receptor kinase CHRK1 contains a chitin-binding activity as well as a kinase activity so that it binds to chitin of fungal cell wall as a chitin receptor, stimulates a kinase domain, and thus effectively activates versatile plant defense systems. Therefore, the receptor kinase CHRK1 of this present invention can be used for developing plants having high resistance to fungi.
