Formation of the riboside-5'-monophosphate is a general feature of the metabolism of cytokinins in plants. As part of a study of the biological significance of the nucleotide form of cytokinins, we analyzed a mutant of Arabidopsis thaliana deficient in adenine phosphoribosyltransferase (APRT) activity for its ability to metabolize N(6)-benzyladenine (BA). Formation of N(6)-benzyladenosine-5'-mo...

plant regeneration was achieved in verbascum speciosum schard. via organogenesis and somatic embryogenesis by culture of mature embryo explants. two types of calli, embryogenic and non-embryogenic, were induced from mature embryo explants on murashige and skoog (ms) medium supplemented with different concentrations of benzyl adenine (ba) and α-naphthalene acetic acid (naa). in order to further ...

present study was conducted to consider the effects of different concentrations of 2,4-d and ba on somatic embryogenesis induction, development and maturation of three strawberry cultivars (kurdistan, parose and camarosa). for this purpose, leaf blade, nodal, petiole, stamen and flower bud calli were cultured on murashige and skoog (ms) medium supplemented with 2, 4 dichlorophenoxyacetic acid (...

Plant growth regulators (PGRs) play a key role in regulating physiological and morphological development of plant species. Application of these PGRs can improve preand post-harvest quality and quantity of ornamental flowers and lessen the harmful effects of injury incurred at harvesting time. The objective of this study was to determine the appropriate spraying solution for improving preand pos...

In an experiment, six levels of benzyl adenine (0.2.5,5.0,7.5,lO.0,12.5 and 15.0 mg/I) in combination with three levels of (CCC) chloro choline chloride (0,125,250 and 500 mg/I) were evaluated against control treatment (0) in each case to find out their optimum levels for microtuberization in potato variety Diarnant. Microtuberization was the earliest by I 3 days at 10 mg/I BA. The number and a...

A novel mixed-ligand copper(II) complex with N-(p-methoxybenzyl)-iminodiacetato(2)) ligand (MOBIDA) and adenine (AdeH) of formula 1⁄2CuðMOBIDAÞðAdeHÞðH2OÞ H2O has been obtained. Its crystal structure reveals the selective formation of a rare Cu– N3(AdeH) bond, closely related to those reported by first time for compounds of general formula 1⁄2CuðBÞðAdeHÞðH2OÞ H2O, with B1⁄4N-benzylor N-(p-methy...

We obtained seven kinds of cDNA clones putatively identified as encoding class III chitinases from cDNA libraries constructed from dichlorophenoxyacetic acid (2,4-D)- and benzyl adenine (BA)- treated rice callus. Putative amino acid sequences encoded in these cDNA clones were compared with those of known chitinases of other plants. Two clones coded for homologues that show high similarity to cl...

In vitro flowering and effective micropropagation protocol were studied in Swertia chirayita, an important medicinal plant using axillary bud explants. The Murashige and Skoog's medium (MS) supplemented with benzyl amino purine (BAP) 1.0 mg L(-1) and adenine sulfate 70.0 mg L(-1) was found optimum for production of multiple shoots. In the present study, incubation of flowering cultures on BAP s...
