Aspartate kinase (EC 2.7.2.4) has been purified 8-fold and characterized from germinating barley (Hordeum vulgare) seedlings. The enzyme is inhibited 50% by 0.7 mm l-lysine and almost completely at 5 mm. l-Methionine does not affect the enzyme on its own, but at low concentrations (0.1-1 mm) increases the inhibition in the presence of lysine, indicating that the two amino acids act as cooperati...

Bu çalışmada fiğ ( Vicia sativa L.), nohut Cicer arietinum L.) ve arpa Hordeum vulgare gelişimi üzerine etkilerini belirlemek amacıyla, bazı Şanlıurfa Baraj Göllerinde yoğun olarak bulunan Microcystis viridis Aphanizomenon gracile’ in karışık kültürünün farklı dozlarının etkisi araştırılmıştır. Siyanobakteri karışımından hazırlanan dozlar, topraklara püskürtülerek uygulanmıştır. Kök uzunluğu ba...

Stomata of barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) leaves failed to open in the light and close in the dark or respond to changes in the CO(2) concentration of the atmosphere in either light or dark when the leaves were in an O(2)-free atmosphere. In contrast, the expected responses to environmental changes were found in atmospheres containing 1.5% O(2). It appears that O(2...

Numerous hybrid and polypoid species are found within the Triticeae. It has been suggested that the H subgenome of allopolyploid Elymus (wheatgrass) species originated from diploid Hordeum (barley) species, but the role of hybridization between polyploid Elymus and Hordeum has not been studied. It is not clear whether gene flow across polyploid Hordeum and Elymus species has occurred following ...

Molecular karyotypes of Hordeum bogdanii Wilensky, 1918 (2n = 14), and Hordeum brevisubulatum Link, 1844 ssp. brevisubulatum (2n = 28), were characterized by physical mapping of several repetitive sequences. A total of 18 repeats, including all possible di- or trinucleotide SSR (simple sequence repeat) motifs and satellite DNAs, such as pAs1, 5S rDNA, 45S rDNA, and pSc119.2, were used as probes...

ABSTRACT. Barley (Hordeum vulgare L.) is one of the most widely cultivated stable food crops in world. grain samples were collected from four selected areas (Bahir Dar, Bure, Finote Selam and Debre Markos) Ethiopia types processed (kolo, porridge, bread injera) prepared it. The levels essential non-essential metals barley grains its determined by microwave plasma-atomic emission spectrometry af...

A new species of a philometrid nematode, Margolisianum bulbosum, is described from the subcutaneous tissue in the mouth (larvigerous females), head (males, ovigerous, and larvigerous females), and eye (preovigerous females) of the southern flounder, Paralichthys lethostigma, from Mississippi Sound. It is placed in a new genus diagnosed by the combination of 8 large, paired but separate cephalic...

Two basic proteins, HLP-1 and HLP-2, were isolated from brewer's barley grain (Hordeum vulgare L.) and characterized as glycoproteins with molecular masses of 16 and 13 kDa and pI values of 7.4 and 8.8, respectively. They could bind sugars, metal ions, and both hydrophobic and hydrophylic molecules of low molecular mass. These characteristics may be related to their potential plant-protecting r...
