摘要

The Japanese pine sawyer Monochamus alternatus is one of the major forest pests. It damages pine directly and transfers the nematode Bursaphelenchus xylophilus to pine wood; resulting in serious economic losses around the world every year. l-tubulin is one of most important proteins in most species. We cloned a ubiquitously expressed M. alternatusl-tubulin gene and analysed its nucleotides and protein structure; its sequence characters are consistent with what have been reported in other insects. The alignment of proteins showed that there is high homology of l-tubulin between M. alternatus and other species. Western blot and immunocytochemistry analyses suggested a common epitope of l-tubulin between M. alternatus and Strongylcentrotus purpuratus. We also expressed the protein in Escherichia coli for further functional studies.
