ID (Ontology) |
FBbt:00007411 (Fly Anatomy) |
| Definition |
Largest of the three main labellar taste bristle types, it is approximately 35 micrometres long (Shanbhag et al., 2001). These taste bristles contain the sensory dendrites of four gustatory receptor neurons (Shanbhag et al., 2001), with mostly invariant receptor expression (Weiss et al., 2011; Jaeger et al., 2018), and one mechanosensory neuron (Shanbhag et al., 2001). The gustatory neurons can respond to sugars, salt and water (Meunier et al., 2003; Fujishiro et al., 1984). Large taste bristles do not respond to bitter stimuli and their gustatory receptor neurons do not express the bitter receptor Gr66a (Weiss et al., 2011).[ FlyBase:FBrf0041338 FlyBase:FBrf0137194 FlyBase:FBrf0152351 FlyBase:FBrf0160792 FlyBase:FBrf0212834 FlyBase:FBrf0240353 ] |
| Also Known As |
"L-type sensillum" ; "long labellar taste bristle" ; "lTB" |
| Comment |
Shanbhag et al. (2001) report that there are between 7 and 9 L-type sensilla, whilst Hiroi et al. (2002), Weiss et al. (2011) and Jaeger et al. (2018) all show 9. Positions are relatively consistent between studies (6 in a relatively medial row, 3 in a relatively lateral row), despite two different numbering schemes. |
