Dear Dr Vandepeer, I am a professor of zoology at Wuhan University in China, I have been working on the evolution of sensory genes for years, please see the link below for more details. http://www.bio.whu.edu.cn/News_reads.asp?cid=174&id=2039 I have a question for you. I noticed that you or your colleagues have annotated chemosensory genes in the spider mite, I am wondering how you annotated those putative chemosensory genes. Because I detected nothing when I used insect chemosenosry genes as query, which suggested those genes of the mite are too divergent to share any sequence similarity with those of insects. Please let me know how you worked this out. Thanks, Huabin -- Huabin Zhao, Ph.D, Professor Department of Zoology, Rm 6108, College of Life Sciences, Wuhan University, Wuhan, Hubei 430072, China Office: (86)-27-68753526 E-mail: huabinzhao@whu.edu.cn; huabinzhao@gmail.com Profile: http://www.bio.whu.edu.cn/News_reads.asp?cid=174&id=2039
