Antiviral roles of plant ARGONAUTES

CARBONELL, ALBERTO; Carrington, James C. (Elsevier, 2015-10)

[EN] ARGONAUTES (AGOs) are the effector proteins functioning in eukaryotic RNA silencing pathways. AGOs associate with small RNAs and are programmed to target complementary RNA or DNA. Plant viruses induce a potent and ...
Argonaute PIWI domain and microRNA duplex structure contribute to small RNA sorting in Arabidopsis.

Zhang, Xiaoming; Niu, DongDong; CARBONELL, ALBERTO; Wang, Airong; Lee, Angel; Tun, Vinnary; Wang, Zonghua; Carrington, James C.; Chang, Chia-en A.; Jin, Hailing (Nature Publishing Group, 2014-11-16)

[EN] Small RNAs (sRNAs) are loaded into ARGONAUTE (AGO) proteins to induce gene silencing. In plants, the 5¿-terminal nucleotide is important for sRNA sorting into different AGOs. Here we show that microRNA (miRNA) duplex ...
Functional analysis of three Arabidopsis ARGONAUTES using slicer-defective mutants

CARBONELL, ALBERTO; Fahlgren, Noah; García-Ruíz, Hernan; Gilbert, Kerrigan B.; Montgomery, Taiowa A.; Nguyen, Tammy; Cuperus, Josh T.; Carrington, James C. (American Society of Plant Biologists, 2012-09)

[EN] In RNA-directed silencing pathways, ternary complexes result from small RNA-guided ARGONAUTE (AGO) associating with target transcripts. Target transcripts are often silenced through direct cleavage (slicing), ...
Key importance of small RNA binding for the activity of a GW motif-containing RNA silencing suppressor

Perez-Cañamas, M; Hernandez Fort, Carmen (American Society for Biochemistry and Molecular Biology, 2015-01-30)

Background: GW/WG motif-containing viral suppressors of RNA silencing (VSRs) have been proposed to act through interaction with Argonaute (AGO) proteins. Results: The activity of a GW motif-containing VSR was found to rely ...
Specific Argonautes Selectively Bind Small RNAs Derived from Potato Spindle Tuber Viroid and Attenuate Viroid Accumulation In Vivo

MINOIA, SOFIA; CARBONELL, ALBERTO; Di Serio, Francesco; Gisel, Andreas; Carrinton, James C.; Navarro, Beatriz; FLORES PEDAUYE, RICARDO (American Society for Microbiology, 2014-10)
