Project Title •Field Evaluation of Transgenic Gypsophila paniculata for Colour Stability and Environmental Impact
Background Information •Gypsophila (Gypsophila sp.) originated in Eurasia, now commercially grown as a cut flower. •It belongs to the Caryophyllaceae family •Common commercial variety is Gypsophila paniculata •Has predominantly white flowers and in rare cases light pink flowers. •Used as filler for floral arrangements and bouquets
Background Information
•Danziger (Israel) has developed new varieties ranging from dark purple and red to light pink through introduction of Pap1 gene.
•NBA requires introduction of GM crops be preceded by generation of biosafety data
•The objective is to evaluate transgenic Gypsophila paniculata varieties for biosafety and pink colour stability. GM Gypsophila Species Name and Habitat
Species name: Gypsophila paniculata L. Common Name: Baby's breath Herbaceous perennial plant grown as an annual crop in hotter climates Modified Trait Conventionally, ornamental Gypsophila is available in predominately one colour- white Very limited varieties and limited climate conditions also light pink Introduced gene Pap1 (Production of Anthocyanin Pigment 1) is a Myb transcription factor Known to regulate the production of phenylpropanoid, including anthocyanin pigments Gene Donor and Vector
Gypsophila varieties are genetically engineered for constitutive expression of the Pap1 gene isolated from Arabidopsis thaliana
Binary transformation vector pCGN1599
Binary plasmid doesn't contain oncogenic genes which lead to the pathogenesis of the natural agrobacterium Research Themes Scientists and Research Themes
