Ogura cytoplasmic male sterility (CMS) in radish (Raphanus sativus) is caused by an aberrant mitochondrial gene, Orf138, that prevents the production of functional pollen without affecting female fertility. Rfo, a nuclear gene that restores male fertility, alters the expression of Orf138 at the post-transcriptional level. The Ogura CMS/Rfo two-component system is a useful model for investigatin...
Hydroxycinnamoyltransferases which catalyze the formation of O-sinapoylcholine (sinapine) using l-0-sinapoyl-ß-D-glucose as acyl donor have been isolated from seeds of radish (Raphanus sativus L. var. sativus) and mustard (Sinapis alba L.) and purified 420and 293-fold, respectively. The enzymes (“sinapine synthase”) had apparent molecular weights of about 60,000 daltons and showed highest activ...
A new micromachined cell lysis device is developed. It is designed for miniature bio-analysis systems where cell lysing is needed to obtain intracellular materials for further analysis such as DNA identification. It consists of muti-electrode pairs to apply electric fields to cells. We adopt the means of using electric field lysing because it can greatly simplify purification steps for preparat...
Polar transport of kinetin-8-(14)C occurred in segments of petioles, hypocotyls, and roots of radish (Raphanus sativus L.). The polarity was basipetal in petioles and hypocotyls and acropetal in roots. In segments excised from seedlings with fully expanded cotyledons, indole-3-acetic acid was required for polarity to develop. In hypocotyl segments isolated at this stage, basipetal and acropetal...
Parasites are commonly associated with vegetable or fruit borne outbreaks of gastroenteritis. Among all pathogenic intestinal parasites, helminthes cause the most number of parasitic infections in humans and animals, especially in developing countries. We conducted a study to determine the extent of parasitic contamination of raw vegetables sold in some markets of Casablanca (Morocco) .Vegetabl...
