| Abstract | Self-incompatibility in the genus Prunus is controlled by two genes at the S-locus, S-RNase and SFB. Both genes exhibit the high polymorphism and high sequence diversity characteristic of plant self-incompatibility systems. Deduced polypeptide sequences of three myrobalan and three domestic plum S-RNases showed over 97% identity with S-RNases from other Prunus species, including almond, sweet cherry, Japanese apricot and Japanese plum. The second intron, which is generally highly polymorphic between alleles was also remarkably well conserved within these S-allele pairs. Degenerate consensus primers were developed and used to amplify and sequence the co-adapted polymorphic SFB alleles. Sequence comparisons also indicated high degrees of polypeptide sequence identity between three myrobalan and the three domestic plum SFB alleles and the corresponding Prunus SFB alleles. We discuss these trans-specific allele identities in terms of S-allele function, evolution of new allele specificities and Prunus taxonomy and speciation. |

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.
