Figure 6. Developmental expression of PxGSTe and PxGSTs genes from Plutella xylostella. Total RNA extracted from 1st and 2nd instar larvae (lane 1), 3rd instar larvae (lane 2), male 4th instar larvae (lane 3), female 4th instar larvae (lane 4), male pupae (lane 5), female pupae (lane 6), male adults (lane 7) and female adults (lane 8) were analyzed by RNA gel blot analysis. The photographs of the ethidium bromide-stained RNA gel before transfer are also shown.
