Explants of leaves, petals, anthers, styles and ovaries of C. speciosus, C. cancellatus, C. gilanicus and C. almehensis were cultured on LS media with three different combinations of NAA and BAP in the dark. Callus and neoformant organs (leaf and corm-like structure and ordinary and contractileroots) were fomd on some of these explants. Corm explants from these species were also cultured on...

Teucrium chamaedrys is regarded as an herbaceous perennial plant from Lamiaceae family that is used as medicinal plants and food from ancient times. Due to the recent developments in tissue culture techniques and extraction of secondary metabolites, this study aimed to investigate the explants of the Teucrium for callus induction and secondary metabolites. The interaction of Auxin hormones incl...

Eclipta alba is a medicinal herb, also known as Bhringraj belonging to family Asteraceae. The plant has hepatoprotective, antimicrobial and hair growth promoting properties. The effect of various phytohormones on in-vitro callus induction and shoot regeneration in Eclipta alba from leaf explant was evaluated. The sterilized explants were inoculated on MS medium supplemented with different conce...

A rapid and efficient protocol was developed for inducing indirect organogenesis using leaf explants of Vitex negundo L. Explants were cultured on MS with different concentrations of 2,4-D and IAA in combination with BAP for callus induction. The frequency of callus induction increased with increasing concentration of IAA (0.3 mg/l) and BAP (0.3 mg/l) at optimal level. The shoot buds appeared e...

A simple and reliable protocol for plant regeneration from petioles of micropropagated plants of kiwifruit [Actinidia deliciosa (A. Chev) Liang and Ferguson, var. deliciosa ‘Hayward’] is described. Morphogenic callus was initiated by culturing petioles taken from in vitro-propagated plants. From the media tested, Cheng’s K(h) medium plus 0.1 μM IAA, 4.5 μM zeatin, and 2% sucrose was the best fo...

The balance between proliferation and differentiation in the plant shoot apical meristem is controlled by regulatory loops involving the phytohormone cytokinin and stem cell identity genes. Concurrently, cellular differentiation in the developing shoot is coordinated with the environmental and developmental status of plastids within those cells. Here, we employ an Arabidopsis thaliana mutant ex...

Salicylic acid (SA) is one of numerous phenolic compounds found in plants with numerous important physiological events. Exogenously application of Salicylic acid (SA) is useful for the growth and development of plants. This investigation aimed to study the improving effect of salicylic acid on the tissue culture of Ziziphus spina-christi. To study its improving effect were used shoot-tip explan...

 Stevia rebaudiana Bert (Asteraceae) is herbaceous plant with sweet leaves, which are the source of sweetener products. The present study focuses on effects of different combination of plant growth regulators on callus induction, callus cell growth and regeneration and volatile constituents from callus of stevia in tissue culture condition. The results of present study showed callus formation p...

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 K...

A highly efficient protocol for in vitro propagation of Rauwolfia serpentina L. was developed that consisted of callus induction, multiple shoot regeneration and rooting stages. Effect of different plant growth regulators, exclusively or in combination on callus induction, multiple shoot formation and root induction, were observed. Maximum callusing (93.65%) were obtained in leaf and stem expla...
