Abstract Several nations across the globe depend profoundly on rice as main food source. research works have been undertaken to improve yield and breeding, specifically concerning plant tissue culture. This paper aims contrast impact of several growth regulator levels callus induction based mature embryo explants. Over a four-week duration, embryos (Amber variant) were planted produce calluses ...

echium amoenum fisch. and c.a. mey. (boraginaceae) is a very popular medicinal plant which is used as a tonic, tranquillizer, diaphoretic, cough remedy, sore throat and pneumonia in iran’s traditional medicine. callus culture of medicinal plants is one of the ways for production of secondary metabolites. in this study, callus culture of e. amoenum and its major secondary metabolite were investi...

the jatropha curcas l., a plant belongs to euphorbiaceae family, which has great economic and medicinally value. there is high amount of oil in seeds of this plant. because of low germination ability of seed, propagation of jatropha curcas via seed is not usual. the purpose of this work is optimizing of jatropha curcas tissue culture for optimization of callus formation and propagation through ...

INTRODUCTION To control the tissue browning phenomenon, callus growth, total phenolics and paclitaxel production, in the current investigation, we evaluated the effects of citric acid and ascorbic acid (as antioxidants) and glucose, fructose and sucrose in callus cultures of Taxus brevifolia. METHODS To obtain healthy callus/cell lines of Taxus brevifolia, the effects of two antioxidants asco...

Epigenetic changes accompanying plant cell dedifferentiation and differentiation are reported in 35S ribosomal DNA (rDNA) of tobacco (Nicotiana tabacum). There was a reduction of CG and CNG methylation in both intergenic and genic regions of the rDNA cistron in fully dedifferentiated callus and root compared to leaf. The rDNA hypomethylation was not random, but targeted to particular rDNA gene ...

We evaluated the effect of low-intensity pulsed ultrasound stimulation (LIPUS) on the remodelling of callus in a rabbit gap-healing model by bone morphometric analyses using three-dimensional quantitative micro-CT. A tibial osteotomy with a 2 mm gap was immobilised by rigid external fixation and LIPUS was applied using active translucent devices. A control group had sham inactive transducers ap...

WU, FANG-SHENG, and H. H. MURAKISHI. 1978. Infection and synthesis rate of southern bean mosaic virus in soybean callus cells under selected cultural conditions. Phytopathology 68:1389-1392. Soybean (Glycine max 'Harosoy 63') callus cells grown in with that of Prince bean callus treated identically or with either Eriksson's or Linsmaier and Skoog's media were infected soybean plants grown in th...

A modern biotechnological technique to obtain useful natural products from plants is to isolate them from their callus cultures. Lallemantia iberica is an annual herb of the Lamiaceae family known for its stimulant, diuretic, and expectorant effects in Iranian folk medicine. The present study investigated the induction of plant callus tissue and identification of its volatile compounds. For thi...
