Additional Information
Statement
Reference

Drives expression in reticular neuropil associated glial cells.

(FlyBase Curators, 2017)

The larval neuropil glial cells are Gs2-positive and comprise ScerGAL4alrm.PD-positive, pros-positive and ScerGAL4NP6520-positive, pros-negative subsets.

(Losada-Perez et al., 2016)

ScerGAL4alrm.PD drives expression in a subset of distal medulla astrocyte-like glial cells with processes to medulla layer M7.

(Edwards et al., 2012)
