Natural Cross-Kingdom Spread of Apple Scar Skin Viroid from Apple Trees to Fungi

open access: yesCells, 2022
Viroids are the smallest known infectious agents that are thought to only infect plants. Here, we reveal that several species of plant pathogenic fungi that were isolated from apple trees infected with apple scar skin viroid (ASSVd) carried ASSVd ...

Survey and analysis of simple sequence repeats (SSRs) present in the genomes of plant viroids

open access: yesFEBS Open Bio, 2014
Extensive simple sequence repeat (SSR) surveys have been performed for eukaryotic prokaryotic and viral genomes, but information regarding SSRs in viroids is limited. We undertook a survey to examine the presence of SSRs in viroid genomes.

Viroids: “living fossils” of primordial RNAs?

open access: yesBiology Direct, 2016
The discovery of the viroid in 1971, which initiated the third major expansion of the biosphere towards smaller living entities—after discovery of the “subvisual” microorganisms in 1675 and that of the “submicroscopic” viruses in 1892—has been officially

Assessment of Viroid Transmission Risk From Citrus Essential Oils

open access: yesPlant Pathology, Volume 74, Issue 5, Page 1356-1365, June 2025.
Citrus essential oils do not inhibit RNA extractions nor real‐time RT‐PCRs and do not contain detectable amounts of citrus bark cracking viroid nor hop latent viroid. Created in BioRender. Pasha, A. (2025) https://BioRender.com/w15t963. ABSTRACT Germany is the world's second largest producer of hops, with a long history of producing high‐quality hops ...

Factors influencing Barley Stripe Mosaic Virus-mediated gene silencing in wheat [PDF]

open access: yes, 2010
Virus induced gene silencing (VIGS) is a technology that has been used primarily to target the virus genome in infected plants. However, if the virus genome carries inserts derived from the host plant, the system could be employed to target the mRNAs ...
