ABSTRACT
The present research work was carried out to observe the effect of various concentrations of Benzyl amino purine (BAP) in terms of multiple shoot induction with special emphasis on qualitative and quantitative changes of proteins during multiple shoot formation. From whole embryonated cotyledons of groundnut. The shoot induction medium containing different concentrations of Benzyle amino purine ranged from 5.0 to 25.0mg/l along with lower concentration of Indole acetic acid (IAA).The multiple shoots were observed in all the BAP concentrations at a varying levels. Among the various levels of BAP, 25.0mg/l of BAP plus 0.50mg/l of IAA was found to be the most effective in terms of multiple shoot induction. The growth parameters like plantlet height, fresh and dry weight also highly influenced by the concentration of the BAP. The root induction was achieved in micropropagated shoots by using Indole butyric acid (IBA) at a concentrations of 1.0 to 5.0mg/l. The mean number of roots, root length was highly influenced by IBA. In all the concentrations of IBA the rooting was associated with moderate and heavily associated basal callusing. The quantitative estimation of protein content in regenerated shoots also increased with higher concentrations of BAP. The SDS-PAGE analysis showed that there was a nine visible bands with 82.2, 76.4, 57.5, 27.6, 23.7, 21.4, 18.2, 16.5 and 12.8 kDa were observed in multiple shoots derived from all the concentrations of BAP. Whereas in whole embryonated cotyledonary explants there was a entirely different protein banding
