英文摘要	Genetic transformation by electroporation of protoplasts is a standard procedure for many plants. However, for the genus Porphyra, the method is not effective because of low viability of protoplasts and is a time-consuming and expensive procedure. Based on the life history of Porphyra, a spore-targeted strategy of genetic transformation was developed, that is, using fresh conchospores of Porphyra haitanensis Chang & Zheng transformed by agitation with glass beads. A SV40 promoter-driven lacZ reporter gene was expressed in conchospores 48 h after the agitation. More transformants were obtained by increasing the agitation time from 10 to 25 s. The maximum number of transformants was more than six out of 1 million agitated conchospores. Transfer of a SV40 promoter-driven egfp gene into conchospores resulted in significant green GFP fluorescence. The expression of lacZ and egfp revealed that this strategy of spore-targeted transformation using glass bead agitation is feasible in P. haitanensis and that the SV40 promoter is effective for monitoring expression of foreign genes in this red algal species.; Genetic transformation by electroporation of protoplasts is a standard procedure for many plants.
