Characterization of microsatellite markers for the vulnerable grassland forb Senecio macrocarpus (Asteraceae)1
UNLABELLED PREMISE OF THE STUDY Development of microsatellite markers for the vulnerable forb Senecio macrocarpus was performed to begin an assessment of its population structure and breeding method to aid in the conservation of the species in Victoria, Australia. • METHODS AND RESULTS Fifteen microsatellite markers were developed for S. macrocarpus from 454 pyrosequencing. The markers wer...
متن کاملExudate flavonoids in some Gnaphalieae and Inuleae (Asteraceae).
Three members of the tribe Gnaphalieae and six members of the tribe Inuleae (Asteraceae) were analyzed for their exudate flavonoids. Whereas some species exhibit rather trivial flavonoids, others produce rare compounds. Spectral data of rare flavonoids are reported and their structural identification is discussed. 6-Oxygenation of flavonols is a common feature of two Inula species and Pulicaria...
متن کاملChallenges to introducing and managing disturbance regimes for Holocarpha macradenia, an endangered annual grassland forb.
Introducing rare plants to new sites for conservation to offset effects of habitat destruction requires detailed knowledge of habitat requirements, plant demography, and management needs. We conducted a factorial experiment replicated at three coastal prairie sites to test the effects of clipping frequency and litter accumulation on seed germination, seedling survival, reproduction, and seedlin...
متن کاملChemodiversity of exudate flavonoids in Cassinia and Ozothamnus (Asteraceae, Gnaphalieae).
The lipophilic exudates deposited on aerial parts of four species of Cassinia and twelve species of Ozothamnus (Asteraceae, Gnaphalieae) have been analyzed for the presence of flavonoid aglycones and some other phenolics. A total of 55 flavonoids were identified, including several rare flavonols. Flavonols are prevailing over flavones, and 8-O-substitution is dominant in both groups. Ozothamnus...
متن کاملSource population characteristics affect heterosis following genetic rescue of fragmented plant populations.
Understanding the relative importance of heterosis and outbreeding depression over multiple generations is a key question in evolutionary biology and is essential for identifying appropriate genetic sources for population and ecosystem restoration. Here we use 2455 experimental crosses between 12 population pairs of the rare perennial plant Rutidosis leptorrhynchoides (Asteraceae) to investigat...
