WebOct 1, 2015 · Using a very stringent definition of differential gene expression, we found a higher percentage of chemosensory genes differentially expressed in the D. sechellia lineage (7.8%) than in the D. simulans lineage (5.4%); for upregulated chemosensory genes, the percentages were 8.8% in D. sechellia and 5.2% in D. simulans. WebOf these, 11 are chemosensory, the other being thermoceptive (Bargmann and Mori, 1997). Eight of the chemosensory neurons (ADF, ADL, ASE, ASG, ASH, ASI, ASJ, ASK) extend dendrites through the amphid pore in the cuticle to be in fairly direct contact with the environment. These cells respond to water-soluble substances.
