| Abstract | Transcription factor (TF) MYB-like proteins are involved in many physiological and biochemical processes. This study isolated the full length cDNA encoding a MYB from the tree peony (Paeonia suffruticosa Andr.), whose GenBank Accession No. is KC282466. The deduced MYB-like protein sequence shares extensive sequence similarity with previously characterized plant R2R3-MYBs, and was named PsMYB1 according to the accepted nomenclature for TFs. Phylogenetic analysis showed that the deduced amino acid of PsMYB1 was closely related to VvMYB30 from grape. The PsMYB1 gene was expressed in all tissues, but it was most strongly expressed in the stem, and least expressed in the root. When exposed to chilling at 4 °C, PsMYB1 was up-regulated at 7 days and then decreased until 21 days suggesting it responded to low temperature, and it might negatively regulate dormancy release. In addition, the PsMYB1 quicker response to the temperature changes in flower buds of complete dormancy release might be that PsMYB1 involved in eco-dormancy and accelerated budbreak. These experiments enhance our knowledge of PsMYB1 and provide more information for understanding the genetic and physiological changes during the dormancy release process in the tree peony. |

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.
