| Abstract | Regulation of gene expression is associated with RNA interference (RNAi) at the posttranscriptional level and chromatin modification in transcriptional silencing during plant development. Dicer-like (DCL) and Argonaute (AGO) proteins, along with RNA-dependent RNA polymerase (RDR), play integral roles in these processes. Many members of the DCL, AGO, and RDR gene families have been characterized in Arabidopsis, rice, maize, and tomato. However, little is known about these genes in grapevine. Here, we implemented a comprehensive bioinformatics analysis of the DCL, AGO, and RDR gene families in grapevine. In this study, a total of four VvDCL, thirteen VvAGO, and five VvRDR genes were identified in grapevine. These genes were categorized into four groups for each family based on phylogenetic analysis. Twenty-two genes were distributed across 11 chromosomes. We detected five segmental or tandem duplication events, which suggested their conserved functions during evolution. In each subfamily, protein motif composition was relatively conserved. The digital EST expression analyses provided a first glimpse of the expression patterns of DCL, AGO, and RDR gene in grapevine. It is worth mentioning that one gene, VvAGO10a, only expressed in the stem, which suggested that VvAGO10a may function in the regulation of siRNAs in the grapevine stem. Gene expression patterns during berry development and under different abiotic stresses were investigated utilizing microarray data. Thus, these detailed investigations provide a foundation for transcriptional silencing-associated gene families in grapevine for future functional genomics studies. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
