Axis tissues, root and shoot, of germinating pea seedlings actively synthesize sterol from [2-14C]mevalonate during the first 3 days of germination. In addition to the intermediates of sterol synthesis, cycloartenol and 24-methylenecycloartanol, these tissues also form the triterpene beta-amyrin. The cyclase catalysing the formation of cycloartenol from oxidosqualene is about four times as acti...

Punicagranatum cv. Malassaveh is one of the most desirable commercial cultivars in Iran. In thisstudy some experiments were conducted to introduce the best hormonal treatments for directadventitious shoot regeneration from mentioned cultivar via cotyledonary explants. For thispurpose, both liquid and agarMurashige and Skoog (1962) (MS) medium supplemented with BAat 2, 4.5, 9, 13 μM alone and in...

Abstract Radish downy mildew (DM) caused by the oomycete Hyaloperonospora brassicae f. sp. raphani is a serious problem in radish crop, an edible root vegetable of Brassicaceae family. The objective this research was to assess germplasm for DM resistance and evaluate response different organs disease under controlled conditions. Forty-four accessions were inoculated at cotyledons true-leaves wi...

Abstract The structure and physicochemical properties of starch isolated from the cotyledon hull faba beans wheat (as reference) were examined using 16 different methods. amylose content in bean was 32% 36%, respectively, that 21%. structurally alike both displaying C-polymorphic pattern, a similar degree branching branch chain length distributions. Wheat had significantly greater prevalence sh...
