“…IR76b is the third identified coreceptor in the olfactory system that is expressed in the main portion of the third antennal segment, but not the sacculus or arista (Benton et al, 2009;Menuz et al, 2014;Hussain et al, 2016;Steck et al, 2018). IR76b is also broadly expressed outside of the olfactory system, including the proboscis (Zhang et al, 2013;Hussain et al, 2016;Chen and Amrein, 2017;Chen and Dahanukar, 2017;Ganguly et al, 2017;Jaeger et al, 2018;Lee et al, 2018;Sanchez-Alcaniz et al, 2018;Steck et al, 2018), legs (Zhang et al, 2013;Hussain et al, 2016;Chen and Amrein, 2017;Ganguly et al, 2017;Lee et al, 2018;Sanchez-Alcaniz et al, 2018;Steck et al, 2018), wings (Zhang et al, 2013;Hussain et al, 2016;Sanchez-Alcaniz et al, 2018;Yanagawa et al, 2019), and abdomen (Supplementary Table 1) (Sanchez-Alcaniz et al, 2018). Moreover, IR76b is detected in larvae (Supplementary Table 2) (Stewart et al, 2015;Croset et al, 2016;Rist and Thum, 2017;Sanchez-Alcaniz et al, 2018).…”
