Functional Analysis of Seed Dormancy Genes by Biolistic Transient Gene Expression in Immature Embryos of Wheat

Seed dormancy genes typically suppress germination and cell divisionCelldivision. Therefore, overexpressing these genes can negatively affect tissue culture, interfering with the generation of transgenic plants and thus hampering the analysis of gene function. Transient expression in target cells is a useful approach for studying the function of seed dormancy genes. Here, we describe a protocol for transiently expressing genes related to seed dormancy in the scutellum of immature wheat (Triticum aestivum) embryos to analyze their effects on germination.
