The ICK/KRP cyclin-dependent kinase (CDK) inhibitors are important plant cell cycle regulators sharing only limited similarity with the metazoan CIP/KIP family of CDK inhibitors. Information is still limited regarding the specific functions of different ICK/KRP genes in planta. We have shown previously that down-regulation of multiple CDK inhibitor ICK/KRP genes up-regulates the E2F pathway and...

The regulation of cytokinin oxidase activity in callus tissues of Phaseolus vulgaris L. cv Great Northern has been examined using an assay based on the oxidation of N(6)-(Delta(2)-isopentenyl)adenine-8-(14)C (i(6) Ade-8-(14)C) to adenine. Solutions of exogenous cytokinins applied directly to the surface of the callus tissues induced relatively rapid increases in cytokinin oxidase activity. The ...

OBJECTIVES This study compared callus formation in distal femur fractures stabilized with locking plates and intramedullary nails to test the hypothesis that locking plates induce less fracture callus than IM nails. DESIGN Retrospective case matched study. SETTING Two orthopaedic trauma centers. PATIENTS 174 distal femur fracture were reviewed to extract cases treated with retrograde IM n...

Wild pistachio (Pistacia atlantica subsp. kurdica) is one of tree species that cover much of the forest in northwest of Iran and used in industries, medicine and as food. The present study describes callus induction of the P. atlantica subsp. kurdica using seedling stem explants and the influence of different plant growth regulators including kinetin, benzyladenine (BA), thidiazuron (TDZ), 6Ben...

Abstract In Indonesia, Curculigo latifolia, popularly known as lemba, is used traditional medicine for antihypertension, antidiabetic, and a food drink additive. Despite the high benefits, this plant difficult to propagate due its low seed viability. Tissue culture offers an alternative propagation, thus providing continuous source of bioactive substances. The study aimed establish efficient me...
