The present study was carried out to build up an efficient protocol for various concentrations of 2, 4D for “Callus formation and somatic embryogenesis in sugarcane (Saccharum spp L.) using various concentrations of 2, 4-D and RAPD analysis of regenerated plants in the laboratory of Biotechnology Nuclear Institute of Agriculture, Tandojam during the year 2015 to 2016. Three sugarcane varieties ...

The process of fracture healing has been described in detail in many histological studies. Recent work has focused on the mechanisms by which growth and differentiation factors regulate the fracture healing process. Rapid progress in skeletal cellular and molecular biology has led to the identification of many signaling molecules associated with the formation of skeletal tissues, including memb...

An experiment was conducted to study the effect of growth regulators on callus induction in rice embryo culture. In this experiment, caullogenesis was initiated from the matured seeds of seven indica rice varieties viz., TRY 1, TRY 2, Pokkali, CSR 10, W.Ponni, BPT 5204 and IR 29. The medium used for this callus induction was Murashige and Skoog (1962) commonly referred as MS medium with six dif...

We describe mutant tissue lines of Arabidopsis that are able to grow in vitro as callus on hormone-free medium. The 14 lines presented here show different hormone autotrophic differentiation behaviors that can be classified into three categories: (a) forming roots (rooty callus), (b) forming shoots or shoot-like structures (shooty callus), or (c) growing without organ formation (callus). Three ...

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...

In order to optimize callus induction in Pistacia atlantica Desf. subsp. kurdica Rech. f., the effect of different plant growth regulator (PGR) combinations were studied. Inflorescence axis explants were cultured on WPM medium supplemented with 1, 2 and 3 mg/L of TDZ or 1, 2 and 3 mg/L of BA, in combination with 1mg/l different auxins: 2, 4-D,  NAA  and IBA . Callus initiation was observed in a...

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...

Comparisons have been made between a sycamore callus (S4) isolated in 1970 and one first isolated in 1958 (S2). Incubation of S4 on media containing different concentrations of auxin and kinetin showed that the ratio of the hormones was the factor which controlled the growth pattern within the tissue. High ratios of auxin: cytokinin favoured a white friable tissue, whereas a compact callus with...
