Progress in research on insect reproduction regulation mechanism |
The team of
Professor Li Sheng from the School of Life Sciences and Institute of Insect Science and Technology of South China Normal University revealed the molecular mechanism of juvenile hormone (JH) signals to promote ovulation and maintain egg shape, which enriched the theoretical basis of hormone regulation of reproduction .

In order to prove the specific JH signal on the ovary, the researchers used the Gal4 strain specifically expressed by ovarian muscle cells and follicular cells to drive the expression of the marker protein GFP, and then genetically recombined with the JH signal indicator strain JHRR-LacZ
.
Through cell co-localization detection, it is determined that JHRR-LacZ signal is specifically expressed in ovarian muscle cells, indicating that JH signal is activated in ovarian muscle cells
