Properties and Regulation of Aspartate Kinase from Barley Seedlings (Hordeum vulgare L.).
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...
متن کاملLysine Catabolism in Barley (Hordeum vulgare L.).
Lysine catabolism in seedlings of barley (Hordeum vulgare L. var. Emir) was studied by direct injection of the following tracers into the endosperm of the seedlings: aspartic acid-3-(14)C, 2-aminoadipic acid-1-(14)C, saccharopine-(14)C, 2,6-diaminopimelic acid-1-(7)-(14)C, and lysine-1-(14)C. Labeled saccharopine was formed only after the administration of either labeled 2,6-diaminopimelic acid...
متن کاملAllelopathic Plants. 19. Barley (Hordeum vulgare L)
Barley is integrated with other crops to inhibit weed growth, through allelopathic interactions. Effects of barley on growth of other crops, weeds and autotoxicity among cultivars result primarily from allelopathy mediated by allelochemicals released from plant components and/or exuded from living roots. A limited number of allelochemicals are identified that contributes to allelopathic effecti...
متن کاملIdentification of a Phytase Gene in Barley (Hordeum vulgare L.)
BACKGROUND Endogenous phytase plays a crucial role in phytate degradation and is thus closely related to nutrient efficiency in barley products. The understanding of genetic information of phytase in barley can provide a useful tool for breeding new barley varieties with high phytase activity. METHODOLOGY/PRINCIPAL FINDINGS Quantitative trait loci (QTL) analysis for phytase activity was condu...
متن کاملEffect of genotype on androgenesis in barley (Hordeum vulgare L.)
Current study was set up to determine the response of 12 Iranian winter diploid barley (Hordeum vulgare L.) cultivars to anther culture on solid FHG induction medium supplemented with 90 mg/l sucrose, 2 mg/l 2,4-D and 0.1 mg/l kinetin. For cold pretreatment each selected spike was kept in a refrigerator at 4 C for 14 days. The experimental design consisted of a completely randomized design (CRD...
