AGROBACTERIUM MEDIATED TRANSFORMATION OF PIGEONPEA (CAJANUS CAJAN LMILLLSP) VAR LRG-41 FROM AXILLARY BUD

A reliable method of plant regeneration has been achieved from Axillary buds. Shoots appeared from explants when cultured on Murashige and skoog (MS) medium supplemented with BAP (Benzyl amino purine), Napthalene acetic acid (NAA) and Kinetin at various combinations. Elongated shoots were rooted with 70.6% rooting frequency in MS medium with indole buteric acid (IBA) at 1.0mg/l. The rooted plantlets were established well in soilrite mixture medium with 91% success and days taken for acclimatization were 12.8 days. This protocol was used in Agrobacterium mediated transformation. The transformation was carried out using the Agrobacterium strain LBA4404 containing the binary vector pCAMBIA2301 harboring npt II as selectable marker and GUS as reporter gene.
