Toll-likereceptor 4 (TLR4) sequence of Indian buffalo population was analysed for the detection of variation within exon2 region. 81 DNA samples representing six different buffalo breeds viz. Jaffarabadi, Marathwada, Toda,Pandharpuri, Mehsana and Chilika were amplified using the primers specific to exon 2 and adjoining intronicsequence. PCR products when resolved on non-denaturing polyacrylamide gel electrophoresis (PAGE) ieldedtwo different variants A and B with almost equal frequency of 0.531 and 0.469, respectively, which rthervaried among the buffalo breeds investigated. Sequencing analysis of buffalo TLR 4 exon 2 revealed 167 nucleotides, coding for 55 amino acids as in other livestock species. Cattle and buffalo had 100% amino idhomology with few changes as compared to sheep and goat. The variants reported in the present study in be used as candidate markers for economically important traits in buffalo.
