Cultured cells of Nicotiana plumbaginifolia, when deprived of exogenous cytokinin, arrest in G2 phase prior to mitosis and then contain cyclin-dependent protein kinase (CDK) that is inactive because phosphorylated on tyrosine (Tyr). The action of cytokinin in stimulating the activation of CDK by

Local expression of the ipt gene in transgenic tobacco (Nicotiana tabacum L. cv. SR1) axillary buds establishes a role for cytokinins in tuberization and sink formation.

The developmental characteristics of a transgenic tobacco line (BIK62) expressing the ipt cytokinin-biosynthetic gene under the control of a tagged promoter were analysed. In situ hybridization and cytokinin immunocytochemistry revealed that the ipt gene was mainly expressed in the axillary buds

CHRK1 encodes a receptor-like kinase that contains a chitinase-related sequence in the extracellular domain in Nicotiana tabacum. In this study, we showed that CHRK1 is mainly expressed in the shoot apex region including leaf primordia and young leaves, and germinating seedlings and vascular

In Nicotiana plumbaginifolia cytokinins affect seedling development by inhibiting root growth and hypocotyl elongation and by stimulating cotyledon expansion. The zea3.1 mutant was selected for its inability to grow in conditions of low nitrogen and for its ability to grow independently on

Zea3: a pleiotropic mutation affecting cotyledon development, cytokinin resistance and carbon-nitrogen metabolism.

When photomorphogenesis takes place during early plant development, the cotyledons undergo a metabolic transition from heterotrophic sink metabolism to autotrophic source metabolism. A mutant screen was devised for seedlings affected in the regulation of nitrate assimilation during this early

Substituted nitroguanidines provide cytokinin activity during in vitro cultivation of plant tissues.

Synthetic nitroguanidine derivatives can be used as alternatives to the traditional adenine-containing cytokinins used in plant tissue culture. First, nitroguanidine derivatives (NG) mimicked the typical activity of two standard cytokinins, 6-benzylaminopurine (BAP) and 2-isopentenyladenine (2iP) in

Light-induced expression of ipt from Agrobacterium tumefaciens results in cytokinin accumulation and osmotic stress symptoms in transgenic tobacco.

Cytokinins are plant growth regulators that induce shoot formation, inhibit senescence and root growth. Experiments with hydroponically grown tobacco plants, however, indicated that exogenously applied cytokinin led to the accumulation of proline and osmotin. These responses were also associated

Cytokinin-habituated, as compared to nonhabituated Nicotiana tabacum cv. Havana 425 callus was shown to tolerate higher concentrations of 5-bromodeoxyuridine (BUdR) if cytokinin was added to the medium [Meins, Planta 129, 239-244 (1976)].Our aim was to clarify whether or not BUdR-resistance and

When cloned pith and leaf tissues of Nicotiana tabacum L. cv. Havana 425 are subcultured for 3 d on auxin-containing medium and labelled for 18 h with [(35)S]methionine, up to 10% of the labelled, soluble-protein fraction is found in a single band with an apparent molecular weight of approx.

The cytokinin, N(6)-(Delta(2)-isopentenyl)adenine, is found to be at least 3.3 times as active as N(6)-(Delta(2)-isopentenyl)adenosine in promoting the growth of cytokinin-requiring tobacco (Nicotiana tabacum) callus. Absorption rates of N(6)-(Delta(2)-isopentenyl)adenine and

Two endochitinases (EC 3.2.1.14) of M(r) values of approximately 34,000 and approximately 32,000 have been purified from cultured tissues of Nicotiana tabacum cv. Havana 425. The chitinase content of cloned tobacco pith tissues subcultured on hormone-free medium increases by approximately 5-fold to

Tissues transformed with the isopentenyl transferase (ipt) gene cloned from the T-DNA region of the Ti plasmid or with the ipt gene placed under the control of the cauliflower mosaic virus 35S promoter (35S-ipt) were analyzed for auxin and cytokinin. Free and total indole-3-acetic acid (IAA) levels

Pith tissue from Nicotiana tabacum L. cv ;Maryland Mammoth' or ;Wisconsin 38' was isolated, free of vascular tissue, and cultured on a medium containing auxin but no cytokinin. Explants from the apical 1 cm of stem, within the pith rib meristem, initiated callus growth with 100% efficiency.

In excised pith parenchyma from Nicotiana tabacum L. cv. Wisconsin Havana 38, auxin (naphthalene-1-acetic acid) together with cytokinin (6-benzylaminopurine) induced a greater than 40-fold increase in a p34cdc2-like protein, recoverable in the p13suc1-binding fraction, that had high H1 histone

The 6b gene of Agrobacterium tumefaciens has been demonstrated to modify the activity of the plant growth regulators, auxin and cytokinin. To study the possible mode of action of the gene, tobacco (Nicotiana tabacum L. cv. Samsun) plants were transformed with the A. tumefaciens C58-6b gene. Seeds
