Regulation of olfactory-based sex behaviors in the silkworm by genes in the sex-determination cascade
Fig 2
Silkworms with mutations in BmMasc, BmPSI, and Bmdsx have abnormal antennal structures.
(A) Gross morphology of antennae of wild-type and mutant males (M) and females (F). Scale bars: 1 mm. (B) SEM images of the sensilla trichoidea structures in the middle of the antennae of wild-type and mutant males. Scale bars: 50 μm. (C) Antennal lengths of wild-type and mutant adults. The results are expressed as the means ± SEM of 10 independent biological replicates. *** represent significant difference at the 0.001 level (one- way ANOVA), compared with the WT-F and WT-M; n.s. indicates that the difference is not statistically significant. (D) The number of sensilla trichoidea in one SEM scan field in wild-type and mutant adults. The results are expressed as the means ± SEM of 5 insects per group. ** and *** represents significant differences at the 0.01 and 0.001 level (one- way ANOVA) compared with the control; n.s. indicates that the difference is not statistically significant.
