| Outline of Final Research Achievements |
White campion (Silene latifolia) is a dioecious flowering plant in the family Caryophyllaceae, also known as a model system for the study of plant sex determination. In this study, for the purpose of the identification of a plant sex-determination gene, we have developed an infection method for VIGS (Virus Induced Gene Silencing) system in S. latifolia. VIGS is an efficient method for gene functional analysis without transformation. To develop the VIGS system using a virus vector localizing in floral meristem tissues, named ALSV, we have optimized the ALSV infection method in S. latifolia. Our developed method resulted in a systemic infection with ALSV, indicating that the VIGS can be applied for the identification of sex-determination gene in S. latifolia.
