Psorospermin is a natural product that has been shown to have activity against drug-resistant leukemia lines and AIDS-related lymphoma. It has also been shown to alkylate DNA through an epoxide-mediated electrophilic attack, and this alkylation is greatly enhanced at specific sites by topoisomerase II. In this article, we describe the synthesis of the two diastereomers of O5-methyl psorospermin...

In this study, waste water drains and produced phosphate fertilizers of conventional wet-process (hemihydrate) phosphoric acid and phosphate fertilizer plants were investigated to determine the average uranium contents in the active manufacturing period. The method chosen for the determination of uranium was an extension of an existing spectroanalytical method and was adopted for waste water an...

Well-characterized rough mutants are important for the understanding of structures, functions, and biosynthesis of lipopolysaccharide (LPS) in gram-negative organisms. In this study, three series of Pseudomonas aeruginosa LPS-deficient mutants, namely PAC strains derived from serotype O3, AK strains derived from strain PAO1 (serotype O5), and serotype O6-derived mutants were subjected to bioche...

The maize (Zea mays) opaque5 (o5) locus was shown to encode the monogalactosyldiacylglycerol synthase MGD1. Null and point mutations of o5 that affect the vitreous nature of mature endosperm engendered an allelic series of lines with stepwise reductions in gene function. C(18:3)/C(18:2) galactolipid abundance in seedling leaves was reduced proportionally, without significant effects on total ga...

Field experiment was conducted at Central Institute of Medicinal and Aromatic Plants (CIMAP), Lucknow to evaluate the growth and yield of geranium and garlic in intercropping system. Maximum dry matter accumulation was noticed during 120-135 DAP. Dry matter accumulation in geranium paired sole was almost equal to geranium paired intercrop. Application of phosphorus at 40 kg P2 O5 ha -1 and 30 k...

Maize starchy endosperm mutants have kernel phenotypes that include a brittle texture, susceptibility to insect pests, and inferior functional characteristics of products made from their flour. At least 18 such mutants have been identified, but only in the cases of opaque2 (o2) and floury2 (fl2), which affect different aspects of storage protein synthesis, is the molecular basis of the mutation...
