Recently, the "Animal Ecology" (Journal of Animal Ecology) published online reveal the results of a recent, widely O.
"Animal Ecology" (Journal of Animal Ecology), a new online publication of the results reveals wide O.
Corresponding author Zhou Zhongshi, researcher, said that in the animal kingdom, females choose to mate with males and usually produce certain "reproduction and survival benefits
The size of the insect usually affects the reproduction ability of the insect
The team's research found that when females choose to mate with large males, they can not only breed more offspring, but also have a higher survival rate of offspring during development, and the intrinsic growth rate, limited growth rate and net growth of the population The rate has also increased significantly
According to the population development forecast, the development trend of the progeny populations that choose to mate with larger males is obviously accelerated
Subsequently, the genes OcACE, OcSFP and OcCBP, which are highly expressed in the testis and accessory glands of large male worms, were screened based on transbankomics and qPCR technology
Furthermore, the expression profiles of different tissues of female and male found that the expression levels of 3 genes in the mating sacs of females at the end of initial mating were more than two times higher than those of other tissues
After silencing three genes in males by RNAi, the fecundity of females mated with them showed a significant decrease
The research was supported by the National Natural Science Foundation of China
