Coltsfoot (<em>Tussilago farfara</em> L.) is a common species, widely used in European and Chinese traditional medicine for the treatment of respiratory diseases. However, raw material from this plant contains hepatotoxic pyrrolizidine alkaloids (PAs). The aim study was to determine variability level PAs (senkirkine senecionine) leaves coltsfoot originated natural populations Poland. In phytochemical analysis, 20 samples <em>T. were used. This obtained Garden Medicinal...

Abstract: Fungal root endophytes were examined in 25 medicinal plant species from 24 genera and 14 families. Arbuscular mycorrhiza (AM) was found 15 species. In roots of these plants, arbuscular mycorrhizal fungi (AMF) with coarse hyphae dominant. The intensity AMF colonization varied particular species, ranging 1.2% (Cannabis sativa) to 78.8% (Salvia przewalskii). fine AM endophyte (Glomus tenue) only 3 morphology 12 the Arum-type, while plants Apiaceae Cannabaceae families revealed...

Summary Plants have developed intricate defense mechanisms against pathogen infections. Immune system of medicinal plants is well developed. The molecular their ability to protect themselves are not fully understood. Little known about RNA-binding proteins (RBPs) present in plants. However, CmGRP1 an RBP found the milky sap plant Chelidonium majus L. what implies possible importance RBPs immunity. In this review recent insights into role antiviral and antibacterial responses discussed.
