Abstract/OtherAbstract:
Molecular diversity within six viroid species and different molecular variants, in each species infecting fruit trees was first estimated by the single-strand conformation polymorphism (SSCP) technique and then by direct sequencing analysis. The different variants studied are to three Australian grapevine viroids(AGVd), four citrus dwarfing viroids (CDVd), eleven grapevine yellow speckle viroids type-1 (GYSVd-1), four hop stunt viroids (HSVd), seven peach latent mosaic viroids (PLMVd), and eight pear blister canker viroids (PBCVd). Polyacrylamide gel electrophoresis (PAGE) conditions were compared and optimized to improve the sensitivity of the existing SSCP parameters. The relationships among the various SSCP profiles observed and the variation in nucleotide sequences was studied. The results indicate that the variations of some parameters of electrophoresis for each species allowed higher resolution and hence detection of single nucleotide variations among clones initially clustered into the same group.
