Photocontrol of Hook Opening in Cuscuta gronovii Willd.
Hook opening in seedlings of Cuscuta gronovii Willd. occurred only after prolonged exposures to blue, red, or far red light. Prolonged far red exposure was less effective than prolonged exposure to red or blue light. Brief far red irradiation inhibited the inductive effect of red light. The far red inhibition was in turn reversed by brief red irradiation. These effects suggest the involvement o...
متن کاملVerbesina alternifolia Tolerance to the Holoparasite Cuscuta gronovii and the Impact of Drought.
Holoparasites are nonphotosynthetic plants that acquire all resources from hosts. The holoparasite Cuscuta gronovii is native to much of the US with a broad host range including Verbesina alternifolia, an understory perennial. Both species grow in moderate to moist soils and occur in habitats that may experience prolonged or episodic drought. We applied the Wise-Abrahamson Limiting Resource Mod...
متن کاملGetting ready for host invasion: elevated expression and action of xyloglucan endotransglucosylases/hydrolases in developing haustoria of the holoparasitic angiosperm Cuscuta
Changes in cell walls have been previously observed in the mature infection organ, or haustorium, of the parasitic angiosperm Cuscuta, but are not equally well charted in young haustoria. In this study, we focused on the molecular processes in the early stages of developing haustoria; that is, before the parasite engages in a physiological contact with its host. We describe first the identifica...
متن کاملAllelopathy and Anti-mitotic Effects of Cuscuta campestris and Cuscuta monogyna Extracts on Plant Cell Division
Some natural compounds of plants including phenols and alkaloids induce mitosis depressive that are blocked cell division. Field dodder (Cuscuta campestris Yunck.) and eastern dodder (Cuscuta monogyna Vahl.) are the most widespread obligatory parasitic species. In the present study, end of summer 2015, field dodder and eastern dodder are collected from Alhagi maurorum Medik. host and Vine (Viti...
متن کاملDifferentiation of Cuscuta chinensis and Cuscuta australis by HPLC-DAD-MS analysis and HPLC-UV quantitation.
Cuscuta chinensis and Cuscuta australis, the two botanical sources of the Chinese herbal medicine Tu-Si-Zi, were distinguished from each other based on qualitative and quantitative chemical analysis. By HPLC‑DAD‑MS, a total of 36 compounds were characterized from these two Cuscuta species, including 14 flavonoids, 17 quinic acid derivatives, and 5 lignans. In addition, HPLC‑UV was applied to de...
