چکیده

Ochradenus baccatus is a medicinal plant of high value, spread over sandy and stony places of Kingdom of Saudi Arabia and most of the desert regions of Egypt. This species contains several flavanoids and specific constituents which are important as these have already been effectively used in lowering cholesterol in the blood of rats and high inhibition potential of the malarial parasite (Plasmodium falciparum). Synseeds were produced from stem segments and apical bud of O. baccatus growing In vitro. Two sets of synseeds were produced, one non-dried and the other dried under running laminar air-flow for 30 min. Regeneration and regrowth were evaluated for 16 weeks storage under various temperatures (4, 8 and 12oC). The maximum frequency of conversion into plantlets was achieved on the MS medium containing 1.0 μM BA in encapsulated nodal segments stored at 4oC. Rooting in these shoots was induced by the pulse treatment of 100 μM IBA for 10 days, and the rooted shoots were transferred on the MS medium devoid of any PGR. Fair percent rooting occurred after one week of transfer on the MS medium. Plantlets were successfully established. No phenotypic variations were observed between the synseed originated plants with mother plant. Genetic stability of synseed grown plants and mother plant was evaluated by inter-simple sequence repeat (ISSR) marker. The mother plant as well as regenerated plants from synseed resulted in a monomorphic banding pattern developed from ISSR markers confirming genetic stability among the clones. This protocol will help multiply and conserve the plant as well as for short-term storage of germplasm for commercial use and exchange.

Infra-Specific Genetic Diversity of Ochradenus Baccatus Delile, a Gynodioecious Species in Egyptian Flora

Ochradenus Delile is a small genus of 6-9 species within family Resedaceae. In Egypt, it is only represented by the gynodioecious Ochradenus baccatus Delile, the most widespread species across the entire range of the genus. Within Egypt, field populations and herbarium specimens of O.baccatus showed vast morphological and gender diversity within and between different populations even in the sam...

Taste and Physiological Responses to Glucosinolates: Seed Predator versus Seed Disperser

In contrast to most other plant tissues, fleshy fruits are meant to be eaten in order to facilitate seed dispersal. Although fleshy fruits attract consumers, they may also contain toxic secondary metabolites. However, studies that link the effect of fruit toxins with seed dispersal and predation are scarce. Glucosinolates (GLSs) are a family of bitter-tasting compounds. The fleshy fruit pulp of...

ORI GIN AL PA PER Friend or foe? Disparate plant–animal interactions of two congeneric rodents

Food and water resources are limiting factors for animals in desert ecosystems. Fleshy fruits are a rare water source in deserts and when available they tend to attract a wide variety of organisms. Here we show that two congeneric rodent species, Acomys cahirinus and A. russatus, employ different fruit eating strategies that result in either dispersal or predation of the small seeds of the dese...

Larvicidal Activity of Selected Xerophytic Plants Against Culex pipiens and Aedes caspius (Diptera: Culicidae)

Methanol extracts of different plants namely, Trichodesma africanum (Boraginaceae), Cleome rupicola (Capparceae) and Ochradenus baccatus (Resedaceae), were tested for larvicidal activity against 4 instar larvae of Aedes caspius and Culex pipiens mosquitoes. All plant extracts tested against Ae. caspius showed 100% mortality at 10μg/ml except the stem of O. baccatus which showed 90% mortality. H...
