| Abstract | Tree peony (Paeonia suffruticosa) is a well known traditional ornamental plant in China and cut flowers of tree peony have potential market value. To understand the involvement of ethylene in the cut flowers opening at the transcription level of ethylene signaling, we isolated two partial cDNAs encoding ethylene receptor Ps-ETR1-1 (GenBank accession no. EU526838) and transcription factor Ps-EIN3-1 (GenBank accession no. EU526839) from tree peony flower petals, and studied the effects of exogenous ethylene and 1-methylcyclopropene (1-MCP), an ethylene action inhibitor, on the expression of Ps-ETR1-1 and Ps-EIN3-1 during vase life. Northern blot analysis revealed that Ps-ETR1-1 and Ps-EIN3-1 exhibited constitutive levels during untreated flower opening, and they responded significantly to ethylene and 1-MCP treatments. In contrast with the control, the levels of Ps-ETR1-1 mRNA in petals were substantially inhibited by both ethylene and 1-MCP, and remained at nearly unchangeable level throughout flower development. Expression of Ps-EIN3-1 was strongly inhibited by ethylene and slightly induced by 1-MCP during flower opening and senescence. These results suggest that the Ps-ETR1-1 and Ps-EIN3-1 genes and their resultant protein may be involved in the ethylene sensitivity and responses of tree peony cut flowers. |

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.
