Viroids

Postby Plavin » Thu Apr 07, 2005 2:51 am

Hi everyone, I was wondering if some viroids are soil-bourne, and if there are soil borne ones... some examples of them or what they are called. Thanks!

Viroids are actually pretty simple. Viroids are infectious agents composed exclusively of a single piece of circular single stranded RNA which has some double-stranded regions. Viroids mainly cause plant diseases but have recently been reported to cause a human disease. Catalytic RNAs are those that have the intrinsic ability to break and form covalent bonds; Viroids are catalytic RNA's (ribozymes) that cleave RNA to produce fragments containing a 5'-hydroxyl and a 2', 3'-cyclic phosphate. I do believe that the Wheat (soil-borne) mosaic virus is indeed a soil-borne viroid. Here is a website of any and every virus that you are probably likely to come into contact with ever: http://www.tulane.edu/~dmsander/Big_Vir ... sList.html
