In order to interpret the structural and functional roles of the lipids in roots, the composition of the lipids of these organs must be determined. A survey was made of the fatty-acid composition of roots of selected crop species. Seeds were germinated under sterile conditions; the lipids were extracted from the roots, methyl ester were prepared of the fatty acids, and the fatty acids were anal...

High-performance liquid chromatography and Sinorhizobium fredii USDA191 nodC-lacZ gene fusion were used to monitor changes in the isoflavonoid content of soybean roots infected with Heterodera glycines isolate TN1. Isoflavonoid concentrations in infected roots of both H. glycines-resistant Hartwig and susceptible Essex soybean were two to four-fold higher than those of uninfected roots 2 and 3 ...

background & aims of the study: vegetables and cereals are considered vital for properly-balanced diet given that they deliver vitamins, minerals, nutritional fiber, and phytochemicals. this study aimed to assess the concentration of as, cu, cd, pb, cr and hg in common vegetables and cereals in urban open markets in varanasi district, india materials & methods: total 260 edible portions of vege...

Background & Aim:A new sustainable tissue-based system is presented by plant hairy roots, preserving all of the several specialized types of cell with critical roles in allowing bioactive secondary molecules to be synthesized more consistently as usual. The system is also essential for studying the production of alkaloid in culture. Experimental: The ...

Erythrocytes from blood of mice infected with Eperythrozoon coccoides for 3 or 4 days agglutinated spontaneously. Washed E. coccoides particles agglutinated washed erythrocytes of uninfected mice. E. coccoides-mediated agglutination of normal mouse erythrocytes would be an excellent system for studies of bacterial adhesion.

In this experiment, 0, 0.125, 0.25, 0.5, and 1.0 ml of each oil dissolved in 1 ml of 95 % ethanol was added to 1 kg of soil containing 370 P. penetrans per kg, and incorporated by shaking. After 10 days at 22 ± 3 C, a four-week-old tomato (Lycopersicon esculentum Mill cv. Bonny Best) seedling was planted in each of six 5-cm-diam plastic pots containing 100 g of treated or untreated infested soi...

BACKGROUND Endogenous dental erosion is that produced by contact of gastric acids with tooth structure. It may affect exposed root cementum/dentine as well as coronal enamel, causing marked loss of mineral. The aim of this study was to determine whether 1.23 per cent acidulated phosphate fluoride gel, if applied to the surface cementum at certain intervals during an erosive acid challenge, coul...

Studies on how washing and storage influence duck egg quality are scarce compared with those chicken quality. The present study investigated the of washed unwashed eggs stored at 7 ºC 25 for 8 weeks. Quality parameters, including Haugh unit (HU), yolk index, thick albumen ratio, pH, air cell size, indicated that deteriorated during prolonged storage, cuticle staining confirmed reduced coverage....
