Orobanche Rapum-Genistae Subsp. Rigens

Orobanche rapum-genistae subsp. rigens is a parasitic plant that lacks chlorophyll and relies on host plants for nourishment. It is commonly found in agricultural areas where its host, such as the root crop horseradish, is cultivated. This species has a unique life cycle that begins with a small, inconspicuous seed that germinates in response to chemical signals from its host. Its roots form specialized structures called haustoria that penetrate the host's vascular system to extract nutrients. Due to its parasitic nature, it poses a threat to crop yields and is often considered a weed in agricultural settings.
