【 摘 要 】

The sequences of the circular viroid-like RNA 2 (virusoid) from two isolates of lucerne transient streak virus (LTSV) have been determined. They both contain 324 residues and share 98% sequence homology. The proposed secondary structures fit a highly base-paired rod-like model as shown previously for viroids and two other virusoids, velvet tobacco mottle virus (VTMoV) and Solanum nodiflorum mottle virus (SNMV). Except for one region of sequence and positional homology (GAUUUU, residues 21–26) LTSV virusoid exhibits limited homology with all presently known virusoids, including those from VTMoV, SNMV and subterranean clover mottle virus.
