3.2 Screening of five target GmolCXEs involved in odor
reception of foraging and mating
In male and female antennae of G. molesta adults, the relative
expression levels of GmolCXE1 and GmolCXE5 were
significantly higher than other esterase genes (Figure 2 A). TheGmolCXE1 and GmolCXE5 were widely expressed in all tissues
of adults in both male and females, whereas their expression in antennae
were higher than other tissues (Figure 2 B and C).
After female adult stimulation, the expressions of GmolCXE1 andGmolCXE5 in the male antennae was induced by about 2- folds
(Figure 2 D).
In the 4th instar G. molesta larvae, the
expressions of seven esterase genes (GmolCXE7 , 10 ,13 , 14 , 20-22 ) were significantly higher in the
head than in the abdomen (Figure 3 A). Among these genes, the
expressions of GmolCXE13 , GmolCXE14 and GmolCXE21in the larva head were significantly up-regulated as much as twice after
fresh ripe fuji apples and crown pears stimulations than those in the
control (Figure 3 B).
