The application discloses CTL-S1 A
gene and an application of miR-let-7 in regulation of reproductive development of drosophila bacterea CTL-S1 The
gene is specifically highly expressed in ovaries of drosophila bacterea, and the expression of the
gene is inhibited by
RNA interference CTL-S1 The expression of the gene can reduce the
hatching rate of
offspring. Through analysis of an
RNA immunoprecipitation double
luciferase reporter
system, it is found that miR-let-7 and CTL-S1 there is a target relationship. Overexpression of miR-let-7 can cause CTL-S1 the expression amount of the gene to be significantly reduced, and a
phenotype similar to the expression of the gene being inhibited by
RNA interference CTL-S1 CTL-S1 CTL-S1 CTL-S1 CTL-S1 CTL-S1 CTL-S1 CTL-S1 CTL-S1 CTL-S1 CTL-S is generated, and the
hatching rate of
offspring is reduced. The application provides a potential gene target for developing a genetic control strategy for destroying the
reproduction of drosophila bacterea, provides a new idea for subsequent biological control of insects by using the sterile technique, and has a wide application prospect.
