Engineering Viroid Resistance
Viroids are non-encapsidated, non-coding, circular, single-stranded RNAs (ssRNAs). They are classified into the families Pospiviroidae and Avsunviroidae, whose members replicate in the nucleus and chloroplast of plant cells, respectively. Viroids have a wide host range, including crop and ornamental plants, and can cause devastating diseases with significant economic losses. Thus, several viroi...

Viroids are autonomously replicating, small singlestranded circular RNA molecules that do not code for proteins and may cause disease in infected, susceptible plants. Viroids have the ability to induce both RNA-mediated transcriptional gene silencing (TGS) and posttranscriptional gene silencing (PTGS) in infected plants. Viroid PTGS has also been demonstrated in a wheat germ extract system. A p...
متن کاملThe viroid and viroid-like RNA database
The viroid and viroid-like RNA database is a compilation of all natural sequences published in journals or available from the GenBank and EMBL nucleotide sequence libraries. Several information regarding these RNA species such as the position of their self-catalytic domains and the open reading frame of the human hepatitits delta virus are provided. The database also includes a determination of...
متن کاملEngineering cellular resistance to HIV.
A remarkable story of bedside-to-bench-to-bedside research is the discovery of the human immunodeficiency virus (HIV) coreceptor CCR5 and the subsequent therapeutic advances made because of this knowledge. Persons who were heavily exposed to HIV and did not become infected were studied, and a homozygous 32-bp deletion (delta32/delta32) was found in CCR5, the gene encoding this transmembrane pro...
متن کاملEvolutionary Constraints to Viroid Evolution
We suggest that viroids are trapped into adaptive peaks as the result of adaptive constraints. The first one is imposed by the necessity to fold into packed structures to escape from RNA silencing. This creates antagonistic epistases, which make future adaptive trajectories contingent upon the first mutation and slow down the rate of adaptation. This second constraint can only be surpassed by i...
