Massive production of small RNAs from a non-coding region of Cauliflower mosaic virus in plant defense and viral counter-defense
Todd Blevins,Rajendran Rajeswaran,Michael Aregger,Basanta Kumar Borah,Mikhail Schepetilnikov,Loïc Baerlocher,Laurent Farinelli,Frederick Meins,Thomas Hohn,Mikhail M. Pooggin +9 more
TL;DR: Surprisingly, CaMV titers were not increased in dcl1/2/3/4 quadruple mutants that accumulate only residual amounts of vsRNAs, suggesting this chimeric virus may serve as a decoy diverting the silencing machinery from viral promoter and coding regions.
Primary and Secondary siRNAs in Geminivirus-induced Gene Silencing
Michael Aregger,Basanta Kumar Borah,Jonathan Seguin,Rajendran Rajeswaran,Ekaterina G. Gubaeva,Anna S. Zvereva,David Windels,Franck Vazquez,Todd Blevins,Laurent Farinelli,Mikhail M. Pooggin +10 more
TL;DR: It is concluded that the majority of viral siRNAs accumulating during geminiviral infection are RDR1/2/6-independent primary si RNAs, and double-stranded RNA precursors of theseSiRNAs are likely generated by bidirectional readthrough transcription of circular viral DNA by RNA polymerase II.
Begomovirus research in India: a critical appraisal and the way ahead.
TL;DR: The major developments in begomoviral research in India in the last approximately 15 years are summarized and future areas that need more attention are identified.

Sequencing of RDR6-dependent double-stranded RNAs reveals novel features of plant siRNA biogenesis
Rajendran Rajeswaran,Michael Aregger,Anna S. Zvereva,Basanta Kumar Borah,Ekaterina G. Gubaeva,Mikhail M. Pooggin +5 more
TL;DR: TAS1c generates a master siRNA that controls a complex network of TAS1/TAS2 siRNA biogenesis and gene regulation and is processed by DCL4 from both ends in distinct registers, which increases repertoires of tasiRNAs.

Deletion and recombination events between the DNA-A and DNA-B components of Indian cassava-infecting geminiviruses generate defective molecules in Nicotiana benthamiana.

TL;DR: The DNA-B-derived def-DNAs were associated with a decrease in levels of DNA-A, with a concomitant change in the symptoms from downward leaf curling in the older leaves to upward leaf rolling in newly emerging leaves, more typical of monopartite begomoviruses as discussed by the authors.
