| Abstract | Transgenic approach is an excellent way for the clarification of gene function, but it is generally difficult to create transgenic plants for most of the fruit trees including peach. Even if transgenic lines are successfully obtained, it will be extremely difficult to evaluate fruit traits due to the long juvenile phase of the plants. To overcome this problem, usage of virus vector is one of the excellent approaches. In this study, we evaluated gene function related to fruit traits in peaches via virus-induced gene silencing (VIGS). Carotenoid cleavage dioxygenase 4 (CCD4) is proposed to be the key factor responsible for carotenoid degradation in white flesh peaches. Then, we knocked down the CCD4 gene in the white flesh peaches (“Akatsuki” and “Manami”) via VIGS system. Resultantly, yellow pigmentation and increased contents of carotenoids including lutein, ß-carotene, ß-cryptoxanthin, zeaxanthin, and violaxanthin were observed in the agroinfiltration portions of the white flesh peaches, which is a direct evidence that CCD4 is a determinant for yellow flesh trait of peach. Our results suggested the possible application of VIGS system for functional studies of the genes related to fruit traits. |

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.
