Development of 16 microsatellite markers within the Camassia (Agavaceae) species complex and amplification in related taxa1
UNLABELLED PREMISE OF THE STUDY The North American genus Camassia is an ecologically important group whose variability and evolution are little understood, being influenced by hybridization and geographic isolation. We developed microsatellite markers to investigate patterns of gene flow, population structure, and taxonomic relationships within this group. • METHODS AND RESULTS Using a tra...

متن کاملA new homostilbene and two new homoisoflavones from the bulbs of Scilla scilloides.
A new homostilbene, named scillabene A (2), and two new homoisoflavones, named scillavones A (3) and B (4), were isolated from the bulbs of Scilla scilloides DRUCE (Liliaceae) along with 13 known compounds comprising a homostilbene, seven homoisoflavones, a xanthone, a lignan, and three nortriterpenes. The structures of 2-4 were characterized as 3,5,4'-trihydroxy-3'-methoxy-4-methyl-trans-stilb...
متن کاملAntimicrobial Activity of Eucosterol Oligosaccharides Isolated from Bulb of Squill (Scilla scilloides)
Antimicrobial activity of methanol extract from bulb of Scilla scilloides as well as the purified eucosterol oligosaccharides (EOs) against bacteria, fungi and alga was evaluated in vitro using paper disc bioassay. EOs including scillascilloside E-1, E-2, E-3 and G-1 were isolated from the bulbs by methanol extraction, gel filtration on Sephadex LH-20 and preparative HPLC. The metabolites were ...
متن کاملPhylogeography of Camassia quamash in western North America: postglacial colonization and transport by indigenous peoples.
Recent human activities have spread numerous plant species across the globe, yet it is unclear to what degree historical human activities influenced plant dispersal. In western North America, Camassia quamash was one of the most important food plants for indigenous peoples, who transported its propagules either intentionally or accidentally. We investigated how human and natural dispersal might...
