In this present era of Genomics, the genomes of many different organisms or plant species are already sequenced and some are being sequenced. As a result,a huge repository of unknown genes or genes with unknown functions has developed and functional genomics has to deal with the problems of such unknowns . We have constructed a novel VIGS vector,using the minimal replicon region of the DNA-A component of the geminivirus, Mung bean Yellow Mosaic India Virus (MYMIV). The vector is incorporated between the left and right border region of standard pCAMBIA vector so that the recombinant vector...
