Expression pattern of PGRP-SC1a, PGRP-SC1b and PGRP-SC2 in the larval gut. Colors refer to the online version only. a Schematic representation of a dissected larval gut. b
PGRP-SC1a and PGRP-SC1b expression pattern in the larval gut of flies associated with L. plantarum. PGRP-SC1a-Gal4, UAS-nlsGFP (green) and PGRP-SC1b-mCherry (red) are coexpressed in the anterior part of the midgut. c
IMD and PGRP-LE, but not PGRP-LC, are required for PGRP-SC1 expression in the gut. Confocal pictures of axenic or L. plantarum-associated larval guts of the following genotypes: SC1b-Cherry(PGRP-SC1b-mCherry), imd-(PGRP-SC1b-Cherry, imdshadok), PGRP-LE-(PGRP-SC1b-mCherry; PGRP-LE112) and PGRP-LC-(PGRP-SC1b-mCherry; PGRP-LCE12). d
PGRP-SC2 expression in adult guts of axenic flies. PGRP-SC2-Gal4, UAS-nlsGFP (green) is expressed in Vtr and in a narrow domain of the Pmg. Pv = Proventriculus.
