Xiao et al. identified functions of α1,4‐galactosyltransferase 1 (α4GT1) in spermatogenesis of Drosophila melanogaster. They found that α4GT1 was expressed at a significantly higher level in the testis than in the ovary of Drosophila, and that the hatching rate was significantly decreased when α4GT1 RNAi males were crossed with w1118 females, with only a few mature sperm present in the seminal vesicle of α4GT1 RNAi flies. They further showed that the individualization complex (IC) in the testes of α4GT1 RNAi flies was scattered and did n...
