Different concentrations and combinations of hormones were used in MS medium to observe callus induction and then plant regeneration using leaf as explant. The rate of callus formation varied in different treatments used. The highest amount of callus (80.67%) was produced on MS medium containing 3.0 mg/l NAA from leaf after 20 days. The highest fresh weight of callus was obtained from 2.0 mg/l ...
Ten commercial sugarcane varieties, N12, N14, N19, N24, N25, N26, N27, 75E247, 84E1334 and NCo376 were tested for suitability for transformation in terms of their embryogenic callus production and transient expression levels. Based on an increase in callus mass over time, varieties N12, N19, N27, NCo376 and 84E1334 outperformed other varieties on Murashige and Skoog medium containing 2,4-dichlo...
Trianthema decandra L. root and root callus extracts of different solvents viz., petroleum ether, chloroform, ethyl acetate and ethanol were tested against both Gram positive and Gram negative bacteria and also against Fusarium spp. Root callus extract of chloroform and ethanol showed significant activity against Bacillus subtilis, B. cereus. Staphylococcus aureus, Staph. epidermis and also aga...
BACKGROUND In the process of diagnosis and treatment of fractures, an X-ray study is typically performed. In modern medicine very important is the development of new diagnostic methods without adverse effects on the body. One of such techniques is ultrasound imaging. It has a high value in imaging most areas of the body, including the musculoskeletal system. Reports on the use of ultrasound in ...
The Silybum marianum (L.) Gaertn. is the dicotyledonous herbs of the Asteraceae family that is important in medical industry. The biological active compound of S. marianum is a mixture of several flavonolignals generally known as silymarin. The purpose of this study was to optimize S. marianum tissue culture for callus induction, silymarin production and comparison of some biochemical traits be...
In micropropagation of Anthurium the most important and sensitive stage, is callus induction from explant. This experiment was conducted in a completely randomized design with factorial arrangement in 4 replications in Sari Agriculture Sciences and Natural Resources University (SANRU) in 2010. The cultivar used in this study is Fire and leaf segments with and without main nervure, were used as ...
One of the tasks in contemporary biotechnology, pharmacology and other fields of human activities is to obtain biologically active substances from plants. They are very essential in the treatment of many diseases due to their actually high therapeutic value without visible side effects. However, sometimes the possibility of obtaining the metabolites is limited due to the reduction of wildgrowin...
Long-term cultivated Fagopyrum tataricum (L.) Gaertn. (Tartary buckwheat) morphogenic and non-morphogenic callus lines are interesting systems for gaining a better understanding of the mechanisms that are responsible for the genetic stability and instability of a plant tissue culture. In this work, we used histological sections and transmission electron microscopy to identify and describe the m...
strawberry is a valuable, nutritious, and economically important fruit all over the world including bangladesh. therefore, there is a demand to develop a suitable variety of strawberry. for this purpose, leaf explants from in vitro grown strawberry plantlets were cultured onto ms medium supplemented with different concentrations and combinations of 2,4-d, naa and ba for callus induction. the mo...
Objective of the study is to screen for in vitro pharmacological activities of 5-Lipoxygenase and cytotoxicity of using methanolic callus extracts of Biophytum sensitivum. In vitro Brine shrimp lethality assay was carried out according to the method of Meyer et al., (1982) and the lipoxygenase inhibition activity was assayed using photometric method as described by Reddanna et al., (1985). The ...
