Abstract: | Reciprocal cross hybridization between DNA-A and ONA-B molecules showed that MYMV genome contains certain regions common to each other. “Common region” of MYMV belongs to the 0.55 kb Kpnl-Clal fragment of DNA-A and 0.25 kb Xbal-Hind III fragment of DNA-B. Hybridization of DNA-A restriction fragments with the full length coat protein region probe to Indian cassava mosaic virus (ICMV) showed the location of MYMV coat protein coding region in DNA-A. The greater extent of homology of ICMV coat protein region falls within the 400 base pair region of Clal-Clal fragment in DNA-A of MYMV-Bg. The homology between ICMV and MYMV-Bg coat protein gene appeared to be less than 50%. Cross hybridization between DNA-A and DNA-B molecules helped to trim out the homologous region and the DNA-A and DNA-B specific probes could be tailored. |
