Figure 2From: Simultaneous tracking of movement and gene expression in multiple Drosophila melanogaster flies using GFP and DsRED fluorescent reporter transgenesTracking movement and gene expression of multiple flies using GFP. Multiple male flies were placed in a vial and tracked simultaneously for 48 hours. Black/white bars indicate the light/dark cycle the flies were cultured under prior to the beginning of the experiment. Activity is expressed as distance moved per hour (cm/hr), and GFP intensity is expressed as average pixel intensity per hour. 3xP3-GFP, transgenic strain I4, 1 day old (Blue). hsp70-GFP, transgenic strain 2MI4, 1 month old (Brown). hsp22-GFP, transgenic strain 1MI1, 1 month old (Black).Back to article page
