| Abstract | A cephalosporin antibiotic, cefotaxime (Omnatax™) promoted somatic embryogenesis and subsequent shoot regeneration in vitro from spindle in sugarcane irrespective of the genotypes as (CoJ 83, CoJ 88 and CoJ 64) culturered on MS medium with 2,4-D (2.5 mgl$^{−1}$) and kinetin (0.5 mgl$^{−1}$). Seven different concentrations of cefotaxime (100, 200, 300, 400, 500, 600 and 700 mgl$^{−1}$) were tested to find the optimal concentration of cefotaxime for somatic embryogenesis from callus cultures. Among the three varieties, calli of variety CoJ 83 incubated on MS medium with 2,4-D (2.5 mgl$^{−1}$) + kinetin (0.5 mgl$^{−1}$) + cefotaxime (500 mgl$^{−1}$) exhibited maximum somatic embryogenesis. To improve shoot regeneration, the callus was transferred to MS medium with BAP (0.5 mgl$^{−1}$) + kinetin (0.5 mgl$^{−1}$) in combination with different levels of cefotaxime. Highest frequency of shoot regeneration was observed in callus of CoJ 83 in the presence of 500 mgl$^{−1}$ cefotaxime. The plantlets could be successfully hardened in polybags and transferred to soil, where they exhibited normal growth. Our results convincingly demonstrated that cefotaxime improves somatic embryogenesis from spindle and regeneration from embryogenic calli of sugarcane and hence can be strongly recommended for rapid and large scale multiplication of sugarcane. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
