Molecular Characterization and RNA Interference Analysis of SLC26A10 From (Stål).

is a member of the SLC26 gene family, but its role in insects is still unclear. We cloned the gene of () and found contained 11 transmembrane regions and a STAS domain. Expression pattern analysis showed expression was more upregulated in adults than in nymphs, highest in the ovary. After injection of double-stranded RNA (dsRNA) of , the mRNA level of significantly decreased and, consequently, the ovarian development of adult females was hindered; the amount and the hatchability of eggs and yeast-like symbionts in mature oocytes decreased. Further study showed that might result in decreased juvenile hormone level and vitellogenin expression. These results indicate that plays an essential role in the reproduction of .
