| Abstract | A novel transcription factor VvWRKY13 was cloned from Vitis vinifera and found functioning in ethylene biosynthesis pathway by mediating ACS2 and ACS8 expression. Grapevine is one of the most economically important plants, and ethylene is a plant hormone related with its growth, development, abiotic and biotic resistance. Until now, the regulators and their mechanism of ethylene biosynthesis are still not well understood. We have cloned a novel gene from a grapevine cultivar ‘Zuoyouhong’ and named it VvWRKY13. By qRT-PCR analysis, VvWRKY13 was found to be ubiquitously expressed in the leaf, stem, flower, fruit, and root tissues, indicating that it is probably involved in numerous processes of grapevine growth and development. Overexpression of VvWRKY13 in Arabidopsis leads to constitutive triple responses and improved ethylene production. Bioinformatics analysis indicated that the promoters of ACC synthase genes ACS2 and ACS8 contain WRKYs specific binding element W-box. As a result, the expression of ACS2 and ACS8 was found to be increased significantly in VvWRKY13 overexpression lines. Together, these data reveal that the novel transcription factor VvWRKY13 is likely involved in ethylene biosynthesis by the regulation of ACS2 and ACS8 expression. |

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.
