The effect of Drosophila attP40 background on the glomerular organization of Or47b olfactory receptor neurons

Qichen Duan, Rachel Estrella, Allison Carson, Yang Chen, Pelin Volkan

The paper shows that the attP40 transgenic landing site in Drosophila disrupts Or47b olfactory receptor neuron glomerular organization, suggesting potential genetic interactions or background effects.
