ginger (zingiber officinale rosc.) is a herbaceous, rhizomatous, perennial, which its rhizomes are used as an important spices and medicine all over the world. the aromatic principles include zingiberine, while the pungent principles are known as gingeroles. callus culture of the plants can produce the same compounds exist on their parent plants. the aim of this work was to evaluate the effect ...

Callus induction and withanolides production through cell suspension culture of Withania coagulans (Stocks) Dunal

In present investigation, for the development of Fusarium tolerant varieties in carnation, highly susceptible cultivars viz. Tempo and Raggio de Sole were used. Calli caraation irradiated to different doses gamma irradiation. And Callus surviving at highest dose rays was mass multiplied on callus multiplication medium (MS +10 μNAA + 10 μM kin). Irridiated calli after multiplication, treated wit...

Background: Sugarcane is a monocotyledonous crop that is cultivated in the tropical and subtropical regions of the world. One of the most important criteria, influencing the efficiency of the sugarcane transformation is known to be related to physical and biological factors during the transformation procedure. Objectives: The objective of this research was to study the response of callus induc...

effects of salinity and drought on growth, contents of proline, malondialdehyde (mda), proteinand activity of antioxidative enzymes were studied in two trigonella species. seeds andexplants of t. foenum-graecum and t. aphanoneura were grown on murashige and skoogmedium (ms) complemented with iso-osmotic concentrations of nacl (0, 100, 150 mm) andmannitol (0, 180, 275 mm). growth and relative wa...

in the present study, an efficient protocol has been developed for callus induction and production of ra in callus culture of satureja khuzistanica for the first time. in vitro callus induction was achieved from young shoot tip explants cultured on ms and b5 media supplemented with different concentrations of iba (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins bap and kin...

Single cells were mechanically isolated from leaf-derived callus of mature Juniperus oxycedrus L. These cells divided and gave rise to callus when plated on medium containing growth regulators. Best plating efficiency was obtained on a modified Schenk and Hildebrandt medium supplemented with 0.6 micro M 2,4-dichlorophenoxyacetic acid and 100 mg l(-1) casein hydrolyzate. Although single-cell-der...

BACKGROUND Calligonum polygonoides L. subsp. comosum (L'Hér.) Sosk. is a plant species belonging to family Polygonaceae. Susceptibility to threaten, presence of various chemical constituents, and many medicinal effects reported for this plant in addition to rareness of in vitro culture studies have fuelled the need for its micropropagation and phytochemical investigations of the produced cultur...

Foliar explants of Nicotiana tabacum cv Xanthi n.c. were cultured on four different media: a basal medium, basal medium plus benzyladenine, basal medium plus 2,4-dichlorophenoxyacetic acid (2,4-D), and the basal medium containing both hormones. No differentiation or cell division occurred in leaf explants cultured on the basal medium. Addition of benzyladenine caused the formation of buds on th...
