| Abstract | DICER-like 3 (DCL3) is a major player in heterochromatic 24-nucleotide (nt) small RNA (sRNA) and long microRNA (lmiRNA) biogenesis, and higher plant DCL3 mutants have been characterized from Arabidopsis thaliana and rice. Here, a tomato DCL3 (SlDCL3) mutant was generated through the use of trans-activated artificial miRNA and characterized. Constitutive trans-activation knocked down SlDCL3 levels by â¼64%, resulting in dramatically decreased 24-nt sRNA levels and a significant increase in 21- and 22-nt sRNAs. The latter was correlated with specific upregulation of SlDCL4 and SlDCL2b, which function in the biogenesis of 21- and 22-nt sRNAs, respectively. Moreover, at the majority of sRNA-generating genomic loci, an almost complete overlap between small RNA signatures of control and silenced seedlings was observed, suggesting that the reductions in 24-nt sRNAs at these loci were compensated for by biogenesis of 21- and 22-nt sRNAs from the same double-stranded RNA substrates. In addition, bioinformatic analysis and reduced expression in SlDCL3-silenced seedlings identified four novel tomato lmiRNAs, two of which were found to be developmentally regulated. Taken together, these results establish the requirement of SlDCL3 for the biogenesis of 24-nt sRNAs and lmiRNAs in tomato and suggest SlDCL4 and SlDCL2b as surrogates for SlDCL3. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
