Background: Ferulago angulata is an important medicinal plant and endemic to Iran which is an endangered Plant. Objective: The aim of this study was to achieve an efficient method for propagation of this plant and evaluation of essential oil content and composition in habitat. Metthods: Essential oils were extracted by hydrodistillation using Clevenger-type apparatus and its composition was ...

A successful means of in vitro propagation of Streptocarpus rexii Lindl. using leaf tissue as the explants is described. Secondary explants were placed on several regeneration media supplemented with various concentrations of indole-acetic acid (IAA) and benzyladenine (BA). Optimal shoot proliferation was obtained on Murashige and Skoog basal media containing 0.1 mg/L IAA in combination with 0....

  This study was aimed to investigate effects of aqueous citric acid (CA) and ascorbic acid (AA) on lipid oxidation in comparison with effect of vacuum packaging in order to find better treatment to delay improper changes in the Persian sturgeon (Acipenser persicus) fillets during frozen storage due to lipid oxidation. In this study traditional packaging, vacuum packaging, ascorbic acid solutio...

The promotive effect of AgNO3 and aminoethoxyvinylglycine (AVG) on in vitro shoot regeneration from cotyledons of Brasska campestris ssp. peklnensls in relation to endogenous 1-aminocyclopropane-1-carboxylic acid (ACC) synthase, ACC, and ethylene production was investigated. AgNO3 enhanced ACC synthase activity and ACC accumulation, which reached a maximum after 3 to 7 days of culture. ACC accu...

BACKGROUND Chlorophytum borivilianum is an industrially valued medicinal crop. Propagation through seeds is not feasible because of low germination percentage and long dormancy period. Therefore, callus culture and plant regeneration can be an alternative to improve this crop production. Also, callus can serve as an alternative source of bioactive compounds. OBJECTIVE To evaluate the effect o...

Background This study was designed to develop a new co-culture system, assess the effect of luteinizing hormone (LH) using sequential media to promote development and increase the quality of 2-cell murine embryos through the 8-16 cell stage to morula and blastocyst stages. MaterialsAndMethods Monolayers for co-culture were prepared from ovine oviduct epithelial cells (OOEC) in DMEM/F12 medium a...

The morphology of citric acid production strains of Aspergillus niger is sensitive to a variety of factors, including the concentration of manganese (Mn(2+)). Upon increasing the Mn(2+) concentration in A. niger (ATCC 11414) cultures to 14 ppb or higher, the morphology switches from pelleted to filamentous, accompanied by a rapid decline in citric acid production. The molecular mechanisms throu...

This study investigated the effects of different PGRs on in vitro plant regeneration Anthurium scherzerianum Schott and acclimatization ex stage. Depending objective each experiment, shoots were induced from callus cultured a modified Murashige Skoog (MS) medium containing cytokinins auxins. Results showed that 90% leaf explants 48% petiole produced callus. A half-strength MS supplemented with ...
