Potato-Spindle-Tuber-Viroid

The Potato spindle tuber viroid ( PSTVd ​​, rarely referred to as potato spindle tuber viroid ) is a pathogen of plants and is one of the viroids. As such, the pathogen has neither a cover nor protein structures, but consists merely of a naked RNA molecule that is resistant by specific folding and formation of hairpin structures against omnipresent RNases.

Work

The PSTVd ​​infects potato plants and caused them in the plant disease " spindle tuber addiction", a, related to the disease, typical spindle-shaped growth of potato tubers. The mechanism of infectivity and pathogenicity are not yet known. The PSTVd ​​was founded in 1971 by Theodor O. Diener on Plant Virology Laboratory, United States Department of Agriculture, Beltsville, Maryland, discovered and characterized.

Genome sequence of the PSTVd

The PSTVd ​​consists of 359 ribonucleotides and has the following sequence:
