| Abstract | Several environmental stimulants and hormones can affect phenolic accumulation in grape berries, but the effects of ethylene and light and their interaction have not been completely deciphered. We measured the accumulation of anthocyanins (ATs) and proanthocyanidins (PAs) in berries of a red-wine grape, Vitis vinifera cv. Cabernet Sauvignon, in four treatments: light exposure with and without ethephon, a commercial growth regulator that quickly converts to ethylene, and box-shading with and without ethephon. Ethephon did not significantly increase the weight and diameter of the berries but altered maturity parameters at 49 days after treatment. Ethephon and light increased the fresh and dry weights of the berry skins, induced the accumulation of total phenolics, total flavonoids, and PAs and up-regulated the transcription of VvLAR1, VvLAR2, VvANR, and VvMYBPA1. Light promoted the accumulation of ATs and the expression of AT biosynthetic genes more effectively than did ethephon. Ethephon and light had interactive effects on grape ripening and the contents of PAs and ATs by the way that light interfered with the effect of exogenous ethephon on endogenous ethylene biosynthesis and the downstream ethylene regulatory pathway. These findings provide new information about the physiological and molecular function of ethylene during berry development and the impact of the interaction between ethylene and light in Vitis vinifera. |

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.
