Attacin gene sequence variations in different ecoraces of tasar silkworm Antheraea mylitta.

ABSTRACT: Attacin gene exists as paralogous conversion and is being used for identification of strain variations in insects based on the sequence variation. Hence, a study was undertaken to analyze the sequence variation of the attacin gene isoforms in the tasar silkworm Anthereae mylitta that exists in the form of different ecoraces depending upon the environment, food plant and location. Comparison of the previously reported attacin sequences with the DNA sequences of attacin A and B genes revealed six amino acid substitutions among the sequences of the ecoraces which however did not affect the functional domain of Attacin. The generated dendrogram clearly indicated unique branches for each ecorace with two separate gene clusters for attacin A and B. The Sarihan ecorace formed a separate sub-group
