Virus-induced gene silencing (VIGS) has developed into an indispensable approach to
gene function analysis in a wide array of species, many of which are not amenable to stable …

Potential safety issues have been raised with the development and release of virus-resistant
transgenic plants. This review focuses on safety assessment with a special emphasis on …

Plants contain more DICER‐LIKE (DCL) enzymes and double‐stranded RNA binding (DRB)
proteins than other eukaryotes, resulting in increased small RNA network complexities …

Systemic signalling is indispensable for the coordination of diverse physiological processes
during development, defence and nutrient allocation. Indirect evidence suggests that plant …

A major antiviral mechanism in plants is mediated by RNA silencing, which relies on the
cleavage of viral dsRNA into virus-derived small interfering RNAs (vsiRNAs) by DICER-like …

In plants, RNA-directed DNA methylation (RdDM), a mechanism where epigenetic modifiers
are guided to target loci by small RNAs, plays a major role in silencing of transposable …

The potato/tomato psyllid, Bactericerca cockerelli (B. cockerelli), and the Asian citrus psyllid,
Diaphorina citri (D. citri), are very important plant pests, but they are also vectors of phloem …

Background RNA-dependent RNA polymerases (RDRs) function in anti-viral silencing in
Arabidopsis thaliana and other plants. Salicylic acid (SA), an important defensive signal …

The term green island was first used to describe an area of living, green tissue surrounding
a site of infection by an obligately biotrophic fungal pathogen, differentiated from …

Studies on Atalantia citroides, a citrus relative, revealed the existence of a viroid not
described previously. The new viroid has a GC-rich genome of 293–294 nucleotides and …
