To clarify the functional differences among G-proteins, we investigated the localization of Gi and G, in the olfactory bulb of rats by both immunohistochemical and immunochemical techniques, using purified antibodies specific to the e-subunits of Gi, (G,,a), G, (G,,a), and G, (G,a), respectively. We found that G,,a is localized exclusively in the accessory olfactory bulb, but it is present at o...

the laelapid mite, gaeolaelapsaculeifer (canestrini) is widespread in soil habitats and feeds on different small arthropods, fungi and nematodes. the development and fecundity of g. aculeifer feeding on rhizoglyphus echinopus (fumouze & robin) as prey was studied at eight different constant temperatures which include: 16, 17.5, 20, 22.5, 25, 27.5, 30 and 32.5 ºc, with relative humidity of 6...

Onion (Allium cepa L.) is widely produced by farmers and commercial growers throughout the year for local use markets as income generation export market in Ethiopia. Field experiment was conducted during 2018 to 2020 cropping season at highland areas of west Hararghe aimed evaluating performance recently released onion varieties. Treatments were composed three varieties such Nafis; Nasik-Red & ...

BACKGROUND AND AIMS Success during the early stages of the life-history of alien plants is essential for invasion to occur. The reproductive components of plant invaders have mostly been studied in species reproducing sexually but little is known about invaders that depend exclusively on vegetative reproduction. In this paper, the importance of the different recruitment stages on population gro...

Muscari armeniacum is one of the important ornamental cut flower in floriculture industry which native to Southern Europe, North Africa, Western Asia and Asia Minor. In this study, bulb explants (basal plate of bulb having meristem), bulb scales and leaf segments from in vitro derived bulblets were culture in Murashige and Skoog (MS) medium with different plant growth regulato...

Bulbus Fritillariae is the most commonly used antitussive herb in China. Eleven species of Fritillaria are recorded as Bulbus Fritillariae in the Chinese Pharmacopoeia. Bulbus Fritillariae Cirrhosae is a group of six Fritillaria species with higher efficiency and lower toxicity derived mainly from wild sources. Because of their higher market price, five other Fritillaria species are often sold ...

To explore the use of Caenorhabditis elegans and related nematodes for studying behavioral evolution, we conducted a comparative study of pharyngeal behaviors and neuronal regulation in free-living soil nematodes. The pharynx is divided into three parts: corpus, isthmus and terminal bulb, and pharyngeal behaviors consist of stereotyped patterns of two motions: pumping and peristalsis. Based on ...

abstract nitrogen is a key nutrient in plant growth and it is necessary for amino acid synthesis. sulfur has very important role in the biosynthesis of the alliums flavor and pungency precursors and potassium improve crop yield and quality. in order to study the effect of ammonium nitrate and potassium sulfate on concentration some of the mineral elements in onion (allium cepa l. azar shahr cv....
