| Abstract | Follicle-stimulating hormone receptor (FSHR) plays an important role in animal follicular development. Polymorphisms in FSHR promoter region likely impact transcription and follicle growth and maturation. In this study, a fragment of ~1.9 kb of cFSHR promoter for Zang, Xianju, Lohmann Brown, Jining Bairi and Wenchang breeds (line) was obtained. Totally 49 variations were revealed, of which 39 are single nucleotide substitutions, one is nucleotide substitution of (TTG) to (CAC) and nine are indels. Polymorphism at −874 site (a 200 bp indel mutation) was identified, and their effects on egg production traits as well as gene expression were analyzed. At this site, allele I$^{+}$ was dominant in Lohmann Brown and Xinyang Brown (a synthetic egg-laying line) lines, but very rare in three Chinese indigenous chicken breeds, namely Jining Bairi, Wenchang, Zang and one synthetic boiler line (Luqin). In Xinyang Brown population, the polymorphism was associated with age at first egg (AFE) (P < 0.05) and its effect on egg number at 37 weeks of age (E37) and egg number at 57 weeks of age (E57) was not significantly different (P > 0.05). The cFSHR mRNA level was not significantly different between three genotypes in small white and small yellow follicles of Xinyang Brown hens, however, allele I$^{+}$ tends to increase cFSHR transcription. |

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.
