Ammonia monooxygenase (AMO) from Nitrosomonas europaea catalyzes the oxidation of ammonia to hydroxylamine and has been shown to oxidize a variety of halogenated and nonhalogenated hydrocarbons. As part of a program focused upon extending these observations to natural systems, a study was conducted to examine the influence of soil upon the cooxidative abilities of N. europaea. Small quantities ...
Nitrous oxide (N(2)O) emission from soils is a major contributor to the atmospheric loading of this potent greenhouse gas. It is thought that autotrophic ammonia oxidizing bacteria (AOB) are a significant source of soil-derived N(2)O and a denitrification pathway (i.e. reduction of NO(2) (-) to NO and N(2)O), so-called nitrifier denitrification, has been demonstrated as a N(2)O production mecha...
BACKGROUND Olive trees (Olea europaea subsp. europaea var. europaea) naturally grow in areas spanning the Mediterranean basin and towards the East, including the Middle East. In the Iranian plateau, the presence of olives has been documented since very ancient times, though the early history of the crop in this area is shrouded in uncertainty. METHODS The varieties presently cultivated in Ira...
BACKGROUND The Mediterranean olive tree (Olea europaea subsp. europaea) was one of the first trees to be domesticated and is currently of major agricultural importance in the Mediterranean region as the source of olive oil. The molecular bases underlying the phenotypic differences among domesticated cultivars, or between domesticated olive trees and their wild relatives, remain poorly understoo...
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all extant European terrestrial and freshwater animals, their geographical distribution at the level of countries and major islands (west of the Urals and excluding the Caucasus region), and some additional information. The Fauna Europaea project comprises about 230,000 taxonomic nam...
Mannitol is one of the primary photosynthetic products and the major phloem-translocated carbohydrate in Olea europaea L., an important crop in the Mediterranean basin. Uptake of mannitol in heterotrophic cell suspensions of O. europaea was shown to be mediated by a 1 : 1 polyol : H+ symport system with a Km of 1.3 mM mannitol and a Vmax of 1.3 nmol min(-1) mg(-1) DW. Dulcitol, sorbitol and xyl...
AAU-Specific RNA Cleavage Mediated by MazF Toxin Endoribonuclease Conserved in Nitrosomonas europaea
Nitrosomonas europaea carries numerous toxin-antitoxin systems. However, despite the abundant representation in its chromosome, studies have not surveyed the underlying molecular functions in detail, and their biological roles remain enigmatic. In the present study, we found that a chromosomally-encoded MazF family member, predicted at the locus NE1181, is a functional toxin endoribonuclease, a...
background: olive ( olea europea ), from the oleaceae family, is known as a phytoestrogen plant compound, containing lignans and phenolic compounds. some studies have shown phytoestrogens to have spermatogenesis-decreasing effects. objective: the present study investigated the effects of a hydro-alcoholic extract of olive fruit on reproductive argons in male rats. materials and methods: the hyd...
