| Abstract | Background Temperature is a key determinant of ectotherms distribution and growth. During the Eriocheir sinensis breeding process, it was observed that crabs in high latitudes and altitude areas with low temperatures undergo diapause, they would overwinter and continue to grow into three-year-old individuals, whose final body size is significantly larger than the normal two-year-old crabs. The hepatopancreas is responsible for maintaining the nutritional balance and energy required for the crab survival. In this study, we aimed to compare the hepatopancreatic proteomic data between three-year-old and two-year-old crabs and clarify the relationship between genes and the final body size phenotype. Results The analysis revealed that differentially expressed proteins were predominantly enriched in essential cellular processes such as ribosome, ribosome biogenesis, RNA degradation, proteasome, mRNA surveillance pathway, and RNA biogenesis. Increasing ribosome usage for protein biosynthesis was found to enhance the crab tolerance to low temperatures and extend their growth period. Simultaneously, the ubiquitin-proteasome pathway was primarily regulated to enhance the degradation of misfolded proteins induced by low temperatures, thus alleviating damage and ultimately resulting in a larger final size for the three-year-old crabs. Conclusion This study provides insights into how low temperatures contribute to individual body size differences and regulate the life cycle, providing a basis for the future artificial breeding of E. sinensis. |

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.
