Transgenic plants expressing sweetpotato swpa4 peroxidase with enhanced tolerance to environmental stresses
(0) We previously characterized 10 peroxidase(POD) cDNA clones isolated from cell cultures of sweetpotato(Ipomoea batatas).Among them,the expression of the swpa4 gene was profoundly induced by a variety of abiotic stresses and pathogenic infections(Huh et al.,1997；Kim et al.,1999；Park et al.,2003；Jang et al.,2004).In order to assess the function of swpe4,transgenic tobacco(Nicotiana tabacum) plants overexpressing the swpa4 gene under the control of the CaMV 35S promoter were generated,and demonstrated that the overexpression of apoplastic swpa4 showed tolerance to a variety of abiotic and biotic stresses.For a better understanding of the roles of swpa4,we are trying to generate swpa4 transgenic sweetpotato under the control of CaMV 35S promoter in overexpression or suppression manner.The molecular cloning and characterization of SWPA4 promoter will be introduced in terms of stress.
