| Abstract | Gossypium hirsutum and G. barbadense are two cultivated tetraploid cotton species with differences in fibre quality. The fibre of G. barbadense is longer, stronger and finer than that of G. hirsutum. To isolate genes expressed differently between the two species during fibre development, cDNA-SRAP (sequence-related amplified polymorphism) was applied. This technique was used to analyse genes at different stages of fibre development in G. hirsutum cv. Emian22 and G. barbadense acc. 3-79, the parents of our interspecific mapping population. A total of 4096 SRAP primer combinations were used to screen polymorphism between the DNA of the parents, and 275 highly polymorphic primers were picked out to analyse DNA and RNA from leaves and fibres at different developmental stages of the parents. A total of 168 DNA fragments were isolated from gels and sequenced: 54, 30, 38 and 41 from fibres of 5, 10, 15 and 20 days post-anthesis, respectively, and five from multi stages. To genetically map these sequences, 104 sequence-specific primers were developed and were used to screened polymorphism between the mapping parents. Finally, six markers were mapped on six chromosomes of our backbone interspecific genetic map. This work can give us a primary knowledge of differences in mechanism of fibre development between G. hirsutum and G. barbadense. |

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.
