Abstract:
Tomato apical stunt viroid (TASVd) has been identified in a 24-year old seed lot of Capsicum annuum produced in Taiwan. It is the first finding of TASVd in this plant species. The isolate could be discriminated from all reported isolates of TASVd based on its nucleotide sequence, which showed only 94.8% identity with the most related genotype of TASVd. This discrimination was substantiated by phylogenetic analysis. Inoculation of a RNA extract of contaminated seeds to healthy pepper plants showed that the infectivity of the viroid had remained over time. Nevertheless, no transmission to seedlings was observed.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
