Figure 1. RNAi against gfp reduces chromosomal GFP expression in spaceflight and ground control (GC).

Animals fed RNAi vector control for 4 d from L1 larvae developed into normal adults in GC and spaceflight conditions. These animals also displayed GFP expression in oocytes and embryos in GC and spaceflight. Animals fed gfp RNAi for 4 d also developed normally to adulthood in GC and spaceflight, and demonstrated a loss of GFP expression in both GC and spaceflight. Scale bars represent 50 µm.
