Friable callus from leaf disks of Rosa hybrida `Tiffany' was initiated within two weeks under dark conditions and 25°C on Murashige and Skoog (MS) medium supplemented with 4 mg.liter-1 2,4-D. Callus was then transferred into MS medium containing 3 mg.liter-1 2,4-D. Within four weeks, rhizogenesis occurred on the callus surface. The rhizogenic calllus was subculture on MS medium plus 3 mg.liter-1 2,4-D every 4-6 weeks. Within six months from initial culture, somatic embryos were developed on the aging callus in darkness.

Abstract (sommario):

Maize (Zea mays L.), also known as the queen of cereals, is one of the most important food crops in terms of food security, the world economy, and global agriculture. The high yield, diverse climate adaptability, and extensive applications of maize in food, feed, and industrial products make it a highly demanding crop. The traditional methods of maize propagation are slow and often result in less yield with undesired traits due to large-scale variations. However, the advancements in agricultural biotechnology, particularly in plant tissue culture, have made it possible to propagate maize cultu

This callus comprised dense meristematic cells which arose near or at the surface of the nodular tissue. Cells containing starch granules often surrounded these meristemoid areas. Shoots could be induced to form on shoot-inducing medium from the meristemoid areas. Vascular connections developed between the parental material and the shoot

Abstract (sommario):

The influence of polyploidity on the accumulation of vindoline in Catharanthus roseus callus cultures was investigated. The callus line (T1) was induced from a tetraploid leaf. Total alkaloids in the callus were extracted and analyzed by LC-MS for qualitification and HPLC for quantification. Results showed that T1 callus cultures could accumulate vindoline to a high level. The highest accumulation of vindoline found in the callus was 0.11 mg g−1 DW. Our results demonstrate that polyploidity could influence the chlorophyll content or chloroplast development and improve vindoline biosynthesis in

Abstract The method for micro-propagation of rubber (Hevea brasiliensis Muell. Arg) by somatic embryo has been conducted. The aim of the research will describe the effect of media used for callus induction on the somatic embryo formation of rubber plants. Embryonic callus had been induction in 3 media, i.e.; MH1, MH2, and MH3. After callus induction, all callus were induced in media for embryo somatic expression. Maturation of cotyledons was performed using liquid media with filter paper as a bridge to absorb the media. The results showed that the percentage of callus was induced differently f

Abstract (sommario):

Plant regeneration is important for vegetative propagation, detoxification and the obtain of transgenic plant. We found that duckweed regeneration could be enhanced by regenerating callus. However, very little is known about the molecular mechanism and the release of volatile organic compounds (VOCs). To gain a global view of genes differently expression profiles in callus and regenerating callus, genetic transcript regulation has been studied. Auxin related genes have been significantly down-regulated in regenerating callus. Cytokinin signal pathway genes have been up-regulated in regeneratin

Abstract (sommario):

Geranium plant (Pelargonium graveolens L'Her) is one of the geranium oil producing plants that has many benefits. Callus culture is a technique that can be used to plant multiplication and increase production of secondary metabolites. This study aims to determine the effect of the concentration of Benzyl Adenine on the formation of geranium callus from petiole and leaf explants. Callus induction was carried out by culturing petiole and leaf explants on MS medium + 0.1 mg.L-1 NAA + Benzyl Adenine (0; 0.5; 1; 1.5 and 2 mg.L-1).

Abstract (sommario):

Mass propagation of Fraser fir [Abies fraseri (Pursh) Poir], a valuable Christmas tree species in the United States, is problematic because methods currently used are inadequate. According to our results with somatic embryogenesis, the culturing methods used with other Abies species are applicable to Fraser fir. Stage 1 somatic embryogenic callus, characterized by suspensor cells and embryo heads, was obtained at low frequency using Schenk and Hildebrandt medium supplemented with 5 mm glutamine, 0.05% casein hydrolysate, 0.01% myoinositol, 2% sucrose, 5 μM benzyladenine, and 0.6% agar.

Parts of one-month seedlings (roots, hypocotyl, cotyledon leaves) were used as explants for the use of the colza. We added growth regulators (BAP, 2,4-D) in different concentration combinations into the nutrient medium for callus initiation. Statistical proce

Based on biometric assessment of callus (intensity of callus formation, proportion of light callus, callus mass) from 32 analyzed trees (16 genotypes represented by two clones), two genotypes with high callus-forming ability were singled out. Analysis of mitosis showed that, although the proportion of aberrant cells in the callus does not exceed the rate of spontaneous mutation forP. sylvestris, the range of viola

Plant callus extracts are potential to be developed as ingredient in skincare products. Tomato callus is supposed to contain protein-derivatives and or other components such as secondary metabolites that play a role in skin regeneration. Therefore the production of calli is important to be studied for callus sustainable supply. This research aims to obtain optimum medium for callus induction and to analyze tomato callus development anatomically. In vitro culture response was assessed in tomato plant (Solanum lycopersicum L. ‘Permata’) for optimum callus induction. Seeds were grown on ¼ MS medi

It is known that genetic diversity is the most important factor in classical and modern plant breeding. The considerable increase in the number of transgenic crops reveals the value of new plant genetic resources. In this study, a set of 12 wheat progenitors were screened for tissue culture parameters such as callus induction, callus weight, regeneration capacity of callus and callus efficiency using mature embryos. Embryos were excised from imbibed seeds of the progenitors. The excised embryos were placed scutellum upwards in dishes containing 2 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D) for
