Iran is one of the most important regions for origin and diversification of wild almond species in the world. Over 20 species, naturally distributed in many regions, have been identified to date in Iran. These can be used as rootstocks in different Prunus species such as almond or peach due to their adaptability to severe (drought) environmental conditions and resistance to some pests and disea...

The cultivated/domesticated peach (Prunus persica var. persica; Rosaceae, subgenus Amygdalus; synonym: Amygdalus persica) originated in China, but its wild ancestor, as well as where, when, and under what circumstances the peach was domesticated, is poorly known. Five populations of archaeological peach stones recovered from Zhejiang Province, China, document peach use and evolution beginning c...

Primulina eburnea, a plant with longstanding history of traditional medicinal use, has emerged as novel calcium-rich vegetable characterized by remarkable abundance soluble and bioavailable calcium within its leaves. However, most the metabolites produced P. eburnea have not been identified, few studies addressed accumulation nutritional ingredients during leaf development. In present study, we...

Six new sesquiterpenoids, paralemnolins J-O (1-6), along with one novel norsesquiterpenoid, paralemnolin P (7), have been isolated from the soft coral Paralemnalia thyrsoides. The structures of metabolites 1-7 were established on the basis of extensive NMR study and chemical methods. The structure of 5 was further confirmed by a single-crystal X-ray analysis. Cytotoxicity of these metabolites t...

this study was undertaken to identify morphological changes in young seedlings of 5 iranian almond species (prunus dulcis, p. eburnea, p. eleagnifolia, p. haussknechti, and p. scoparia) under polyethylene glycol-induced drought stress. drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...
