Research interest

Because of their enormous diversity, orchids are attractive subjects to study the evolutionary basis of flower shape. For this it is necessary to understand which genes are involved in establishing orchid floral morphology and symmetry. As study organism Erycina pusilla was chosen because of its small, relatively simple and fully sequenced genome, its short generation time and the availability of tissue culture stocks providing flowering plants throughout the year. Expression of genes involved in orchid floral developmental changes are being investigated using various techniques.


tcp genes, de novo genome assembly, mads-box genes
