Abstract
The study presents first report of Agrobacterium mediated genetic transformation in Rice paddy herb (Linmophila aromatica). A. tumefaciens strain C58C1 harboring pBin19 Plasmid containing ?-glucuronidase (GUS) and neomycin phosphotransferase II (nptII) gene, under the control of 35S promoter and NOS terminator was used. Shoot tip explants were inoculated for 30 min followed by co-cultivation for 72 h and selected on agar semi solidified MS medium containing 100 mg/l Kanamycin and 1.0 mg/l BA; whereas total number of 78 putative transgenic shoots were obtained. The shoots were rooted on MS medium containing 1.0 mg/l IBA and 100 mg/l Kanamycin where 43 plants survived and rooted. Expression of GUS gene in the putative transgenics was confirmed by histochemical GUS assay. Visible localised gus expression was noted in a few cells and callus tissues of 4 plantlets that were photographed using compound light microscope.
