Recently, we have isolated tomato leaf curl Java virus, a whitefly-transmitted monopartite begomovirus, which belongs to the family Geminiviridae. ToLCJAV have been shown to be associated with a novel signal stranded DNA satellite, known as βDNA. Post transcriptional gene silencing (PTGS) in plants is a natural defense response against virus infections, and as a counter defense strategy, viruses have evolved to encode silencing suppressor proteins. The present work we have identified the suppressor activities encoded by βC1 protein encoded by ToLCJAV DNAβ satellite, which poses a serious threat to Indonesia. http://dx.doi.org/10.1038/npre.2009.3317.1 Mon, 08 Jun 2009 09:37:20 UTC Functional analysis of βC1 protein encoded by Tomato leaf curl Java virus, a monopartite begomovirus doi:10.1038/npre.2009.3317.1 2009-06-08 Pradeep Sharma Nature Precedings 2009-06-08T09:37:20Z Poster Plant Biology http://creativecommons.org/licenses/by/3.0/
