Primrose (Primula spp.), in the Primulaceae family, blooms early spring and is produced as a seasonal flower or potted ornamental. Even though primroses can be propagated by separating offspring from mother plant, reproduction coefficient low irregular late germination seen their seeds that prevent mass production. Therefore, with this study, it was aimed to production of wild primroses, which ...

To maximize the economic benefits of Hyacinthus orientalis L., micropropagation and morphogenesis induction five cultivars were investigated under four different concentrations indole acetic acid (IAA) with two cytokinins, benzyl adenine (BA), or kinetin (Kin). Days for initiation shoot formation in red fewer than blue white cultivars. Blue showed an increase fresh weight chlorophyll content ei...

Plastidic uracil salvage is essential for plant growth and development. So far, PLUTO, the plastidic nucleobase transporter from Arabidopsis thaliana is the only known uracil importer at the inner plastidic membrane which represents the permeability barrier of this organelle. We present the first homology model of PLUTO, the sole plant NCS1 member from Arabidopsis based on the crystal structure...

This investigation was carried out at the Tissue Culture Lab., Biotechnology Research Center (BTRC) in Tripoli, Libya 2009 to establish a micro propagation protocol for two hybrids of Tomato which several factors were studied including effect concentration growth regulator on shoot multiplication, and rooting explant MS media. Shoot tips cultured into (MS medium) with different concentrations b...

The artichoke (Cynara scolymus) belongs to Asteraceae family. It is included in British and European Pharmacopeia has long–used traditional medicine several countries. plant primarily grows North Africa Mediterranean; addition, it cultivated around the world. Artichoke wildly distributed Iraq at watery lines boundary of field. aim study was induce callus from leaves as explants, compare between...

We present evidence that the size of an active site side chain may modulate the degree of hydrogen tunneling in an enzyme-catalyzed reaction. Primary and secondary kH/kT and kD/kT kinetic isotope effects have been measured for the oxidation of benzyl alcohol catalyzed by horse liver alcohol dehydrogenase at 25 degrees C. As reported in earlier studies, the relationship between secondary kH/kT a...

A study was conducted to determine the optimum concentration of benzyladenie (BA) and gibberllic acid (GA3) to break the dormancy of gladiolus corms in relation to storage period and to find out the effect of BA and GA3 on growth and development of gladiolus corm and cormels. The effect of GA3 on dormancy breaking was most pronounced in the 100 ppm treatment being 26.93 days while in the water ...

The molecular geometry of complex of adenine with 8 water molecules was calculated with Hartree-Fock (HF). The standard 6-31G(d) basis set has been employed. The existence of C-H…O Hydrogen bonds between the water molecules and the hydrophobic part of nucleobase is stablished. We optimized structures and computed interaction energies of all complexes of adenine with water molecules step by step...

Carob (Ceratonia siliqua L.) is an underutilized traditional crop in the Mediterranean regions that has gained much interest due to its high nutritional traits and resilience drought salinity. However, conventional methods of carob propagation are not enough meet increasing market demands. The present study analyzes what extent benzyl adenine (BA) treatments (0.1, 0.5 1.0 mg L−1) alone or combi...
