Webbgametes. The hormones produced by the gonads are not only important for the production of gametes but also for functions in target tissue distant from the gonads, e.g. the induction of reproductive and other behavior in the brain. In the testes, sperm-producing Sertoli cells and testosterone-produc ing Leydig cells can be differentiated. WebbTo solve the long-suffered hybrid sterility in inter-subspecific hybrid rice, the authors performed a genome design and determined that four loci, S5, f5, pf12 and Sc, are the minimal targets for overcoming inter-subspecific hybrid sterility. The pf12 gene was cloned and its artificial neutral alleles at this locus that can rescue hybrid fertility were created.
