The biophysical properties of plantar callus and the relationship between pressure and callus development and regression
Plantar calluses are common skin lesions which often require professional treatment by podiatrists. They commonly present under prominent areas such as the metatarsal heads and can cause significant discomfort during ambulation. Furthermore, they are one of the known risk factors for ulceration in …

Metabolite Production in Callus Culture of Burdock (Arctium lappa L.)
… The objectives of this research were to develop callus culture technique for phytochemical production from burdock for eventual medical usage, and analyze these potential medicinal metabolites. The metabolites in burdock we were most interested in were phenolic compounds because of their high …

Callus Development and Organogenesis in Cultured Explants of Cowpea (Vigna unguiculata (L.) Walp
… and cytokinins resulted in the formation of callus and rhizogenesis. Calli that were formed were separated into six classes based on color and texture. Yellowish friable callus, yellowish compact, soft yellowish callus and green and white were composed of largely vacuolated cells and were …

The study of wheat striate mosaic virus (WSMV) in wheat callus tissue culture
Callus cultures have been developed from intercalary meristem of wheat (Triticum durum, Desf. 'Ramsey') infected with wheat striate mosaic virus (WSMV) and healthy wheat.Electron microscopy of thin sections derived from virus-infected calli showed WSMV particles both within the nuclear membranes …

Attempts to cause differentiation of callus tissue of Abies concolor by tissue culture technique
… species of conifers have been grown in-vitro as callus.The review of literature also indicated that a variety of growth regulators, supplements and conditions of growth were utilized in promoting differentiation and the development of plants from callus. Since no consistent patterns emerge as …

Genetic analysis of androgenetic competence and plants regenerated from callus culture of diploid potato species
… regenerated potato plants following anther and callus cultures, 20 callilines of two S. phureja clones were examined. Four of 20 callilines selected for fertility and diploidy were morphologically indistinguishable among themselves and from the parental clone that had not undergone a tissue …

Propagation of asparagus (Asparagus officinalis L.) via somatic embryogenesis
… technique, the first step is the initiation of callus followed by the induction of the embryos and their developments into plants. The optimized concentration of cytokinin and kinetin for callus formation from in vitro green stem explants of two asparagus genotypes (CRD 168 and CRD 100) was …

Callus Culture as a Prospective Biosensor: Examining Fusarium graminearum Infection and Exploring the Use of RUBY as a Pathogen-Inducible Reporter
… for rapid plant pathogen detection: transgenic callus culture. Callus is comprised of masses of undifferentiated cells, appealing for this application due to its potential to serve as a compact model of whole plants, including response to threats of plant pathogens. When transformed with a …

Induksi kalus pegagan (Centella asiatica) pada media MS dengan penambahan zat pengatur tubuh 2.4-D yang dikombinasi dengan air kelapa
… secondary metabolites can be obtained through callus culture. This study aims to determine the concentration of a combination of 2,4-D PGRs with coconut water on the most effective MS medium to induce callus from leaf explants of Pennywort (C. asiatica). This study was designed using a …

Efficient production of doubled haploid plants through antimicrotubule agent treatment of anther-derived maize callus and the RFLP analysis of the maize anther culture response
… doubling of maize anther-derived haploid callus before plant regeneration. Without treatment with these agents, all the plants regenerated from the callus were haploid. More than 50% of the plants regenerated from the callus treated with 0.625 or 1.25 uM colchicine for 1 to 3 days, 5 to 10 …

Free radical mediated mechanisms in stress and development in in vitro crop plant systems
… (HNE) and malondialdehyde (MDA) inhibit callus proliferation and development (as somatic embryogenesis). Removal of the aldehydes led to a reversal of inhibitory effects.<br/><br/>For the first time, HNE and MDA were measured in extracts of callus generated from different explants of …

Development of novel in vitro systems for natural anthocyanin production
… We found that 2,4-D was necessary to induce callus culture. WPM salts supplemented with sucrose 30%, IAA 2.26 $\mu$M, zeatin 3.49 $\mu$M, and pH 5.7 (adjusted prior autoclaving) was optimal for growth and anthocyanin production in callus cultures. In cell culture suspensions, the medium …

Oh cryoprotectant, wherefore art thou cryoprotectant? Investigation of the permeation of common cryoprotectants into live rice callus cells by coherent Raman microscopy
… can be directly imaged inside living rice callus cells. Readers are first introduced to the cell system, rice callus cells, and the analytical technique, coherent anti-Stokes Raman scattering (CARS) microscopy. Then, they will learn about initial static experiments searching for the …

PHYSIOLOGICAL STUDIES USING TISSUE CULTURES OF PLATYCERIUM CORONARIUM (KOENIG) DESV
… to estimate ploidy level in P. coronarium. Callus was induced from both gametophyte and rhizome explants. Cell suspension culture was successfully initiated from gametophyte-derived callus and plating of cells on semi-solid MS medium with kinetin resulted in the production of two population, …

Respon pertumbuhan kalus stevia (Stevia rebaudiana B.) pada media MS dengan penambahan zat pengatur tumbuh 2,4-D yang dikombinasikan dengan air kelapa
… and to obtain high secondary metabolite through callus culture. 2.4-D is the most frequently used to induce callus due to its stability compared to other type of arcsines. Coconut milk is used to mediate a combination because they have activities such as cytokinins which help cell splits, …

Predictive modelling of the form and development of bone fracture healing
… rate of bone healing, measured in terms of callus stiffening per week, and the percentage of interfragmentary strain, can be described mathematically, and 2) the spatial distribution of callus tissue around a fracture can be modelled computationally based on compressive principal strains …
