FIG. 1.

Schematic representation of the cosmids derived from RRV26-95. Open boxes represent the terminal repeat regions of various lengths ranging from <1 kb to approximately 28 kb. The gray bars indicate the extent and location of each cosmid insert within the parental RRV26-95 genome (top black bar). Each cosmid insert was cloned into the pSuperCos 1 vector following the addition of an ICeuI homing endonuclease linker. The cosmid insert designated ah28ΔA/H was derived from the removal of the AscI-HindIII fragment from the ah28 cosmid within the pSuperCos 1 vector.
