background and objectives:drimia maritima (l.) stearn also known as squill is a medicinally important plant that has been used for various ailments such as dropsy, respiratory disorders, jaundice and epilepsy from ancient times. proscillaridin a is identified as one of the most effective compounds in the plant with remarkable pharmacological features including efficacy against congestive heart ...

Natural selection, random processes and gene flow are known to generate sex ratio variations among sexually polymorphic plant populations. In gynodioecious species, in which hermaphrodites and females coexist, the relative effect of these processes on the maintenance of sex polymorphism is still up for debate. The aim of this study was to document sex ratio and cytonuclear genetic variation at ...

This research aimed to assess the anti-inflammatory and antioxidant potential of methanol extract Wilckia maritima, a plant belonging family Brassicaceae, which is enriched with natural antioxidants. Qualitative phytochemical studies showed presence numerous compounds including glycosides, phenols, triterpenoids, GC-MS revealed 35 bioactive components, n-hexadecanoic acid (26.96%), 9,12,15 octa...

Thermotoga maritima is the most thermophilic eubacterium currently known and grows up to 90 degrees C by a fermentative metabolism in which H2, CO2, and organic acids are end products. It was shown that the production of H2 is catalyzed by a single hydrogenase located in the cytoplasm. The addition of tungsten to the growth medium was found to increase both the cellular concentration of the hyd...

Pyruvate kinases (PK, EC 2.7.1.40) from three hyperthermophilic archaea (Archaeoglobus fulgidus strain 7324, Aeropyrum pernix, and Pyrobaculum aerophilum) and from the hyperthermophilic bacterium Thermotoga maritima were compared with respect to their thermophilic, kinetic, and regulatory properties. PKs from the archaea are 200-kDa homotetramers composed of 50kDa subunits. The enzymes required...

Abstract This study explores the food plant spectrum of sugar beet weevil ( Asproparthenis punctiventris Germar; Coleoptera: Curculionidae), one most important pests Beta vulgaris subsp. Altissima group). It examines potential various weeds and other plants to maintain populations A. adults larvae outside fields. To this end, leaf consumption females males on twelve Amaranthaceae six Polygonace...

The genus Oxyrrhis is a heterotrophic dinoflagellate found in diverse marine environments. spp. have received attention owing to their ecological and industrial importance, high lipid contents, docosahexaenoic acid formation. To the best of our knowledge, contrary O. marina, ecophysiological characterization studies on maritima not yet been reported. Therefore, we investigated taxonomy ecophysi...

In mesophilic prokaryotes, the DNA-binding protein HU participates in nucleoid organization as well as in regulation of DNA-dependent processes. Little is known about nucleoid organization in thermophilic eubacteria. We show here that HU from the hyperthermophilic eubacterium Thermotoga maritima HU bends DNA and constrains negative DNA supercoils in the presence of topoisomerase I. However, whi...

Ardenticatena maritima strain 110S is a filamentous bacterium isolated from an iron-rich coastal hydrothermal field, and it is a unique isolate capable of dissimilatory iron or nitrate reduction among the members of the bacterial phylum Chloroflexi. Here, we report the ability of A. maritima strain 110S to utilize electrodes as a sole electron acceptor and donor when coupled with the oxidation ...
