Additional Information
Statement
Reference

Expression of ScerGAL4Gr28b.c.PT is seen in approximately 45 neurons per labial palp. ScerGAL4Gr28b.c.PT is found to be expressed in single neurons associated with the ventral cibarial sense organ, dorsal cibarial sense organ and the labral sense organ. Expression is found in at least two taste neurons and also in several non-chemosensory neurons associated with the fifth tarsal segment. Expression of ScerGAL4Gr28b.c.PT is seen in a single, large cell at the base of the maxillary palpus that is not an olfactory sensory neuron. Expression is seen in approximately 5 neurons of, or near, the Johnston's organ. Expression of ScerGAL4Gr28b.c.PT is seen in leg neurons thought to be stretch receptors or proprioreceptors. Expression of ScerGAL4Gr28b.c.PT is seen in multidendritic neurons of all abdominal segments of the larvae.
