    The effect of phenolic amino acids on differentiation of DNA, RNA, proteins and cell growth in Cicer arietinum L.
    (Mbr Press Inc, 1999) Otludil, B; Akbayin, H; Taskin, T; Demir, R
    The effect of three amino acids (phenilalanine tyrosine triptophane) have been examined on differentiation of DNA, RNA, protein synthesis and cell growth in cell culture for Cicer arietinum L. cultivated in Murashige and Skoog medium. The Cicer arietinum L, culture were treated with 20, 40,60,80 and 100 mu g. levels of each phenolic amino acid. Amount of DNA, RNA, proteins and cell growth were determined by the levels in the time intervals of 24 h incubation time during 6 days. Obtained data were evaluated statistically Consequently, experimental results reveal that excessive amount of phenolic amino acids cause significant inhibition on RNA, protein and cell growth. Phenilalanine not strongly effect on DNA synthesis or activity of DNA polymerase was unaffected by phenilalanine but tyrosine and triptophane has significant effect on DNA. On the other hand, it has been supposed that extreme amount of phenolic amino acids may be converted to phenolic compounds by cell regulatory systems.

    The formation of callus cultures from unpollinated pistils in cotton plant (Gossypium hirsutum L)
    (Mbr Press Inc, 1998) Taskin, T; Demir, R; Otludil, B; Colak, G
    In this study, unpollinated floral buds of cotton (Gossypium hirsutum L.) were cultured on the Murashige and Skoog (MS) media containing Kinetin (Kin) and Indol Asetic Acid (IAA) at different concentrations for the callus cultures, The nutrient medium containing 2 mg/l Kin + 1 mg/l IAA was observed to be the best medium for the callus formation from ovule and ovarium tissues.

    The formation of partenocarpic grapes in in vitro conditions from flowers of Vitis vinifera L. Cardinal
    (Mbr Press Inc, 1999) Namli, S; Taskin, T; Basaran, D
    In this study, we aimed to transform the flowers of Vitis vinifera L. cv. Cardinal into the berries at in vitro conditions. For this purpose, we used the modified Murashige and Skoog nutrient media (1) nutrient media containing 2 mg/l BAP (M1), 1 mg/l BAP + 1 mg/l 2,4-D (M2) and 0,1 mg/l BAP + 1 mg/l 2,4-D (M3). Pistils were grown only in nutrient media containing 2 mg/l BAP (M1), but not in other media.

    Spectral and antifungal studies of transition metal complexes of N,N?-ethylenebis(salicylideneimine)
    (Maik Nauka/Interperiodica/Springer, 2004) Temel, H; Taskin, T; Sekerci, M
    Mixed ligand Schiff base complexes of Ti(IV), Co(11), Ni(II) and Cu(II) derived from salicylaldehyde and 1,2-diaminoethane have been synthesized and their spectral studies carried out. The complexes have been characterized by elemental analysis, molar conductivities, magnetic measurements, H-1 NMR, UV, visible and IR-spectra. The antifungal effects of the mixed ligand Schiff base complexes of Ni(II), Cu(II) and Ti(IV) on Fusarium oxysporum ssp. melonis and Alternaria sp. were investigated. Antifungal effects on pathogen fungi have been observed with each complex in the study. The complexes inhibited fungi growth at a 66.7 mug/ml concentration of Ni(II) complex, and at a 133.3 mum/ml concentration of Cu(II) and Ti(IV) complexes.
