Absence of Figla-like Gene Is Concordant with Femaleness in Cichlids Harboring the LG1 Sex-Determination System
Round 1
Reviewer 1 Report
In the present study, the authors identified a male-specific figla-like gene in Coptodon zillii, Sarotherodon galilaeus, O. mossambicus and O. niloticus of the Amherst and Chitralada hybrid stock, harboring the LG1 sex-determination system. The finding is interesting.
Major:
1. The sex patterned SNPs of As, Cz and Sm spanning from 25.4 to 28.7 Mb on the Oa map should be included as supplementary data, to help understand how the six sites were obtained.
2. Visualization of the alignment of the male specific region of figla-like of As, Cz and Sm with Integrative-Genomics-Viewer (IGV) should be included in the MS.
3. Protein sequences of Cz, Oh and Cs were not included in Fig.2a.
4. Species used for Fig.2a, Fig.2b, Table 4 and Figure S2 should be consistent.
5. The authors should add some discussion to explain why “distances based on figla-like and barcode sequences were contradictory”.
6. Line 392, it is difficult to understand why On females (xx/ZZ/XX) was female fish. The authors should discuss more.
7. Table 5, AmhΔY (Y) should be changed to amhy, as both gain of function and loss of function experiments have proved that amhy is the sex determining gene on LG23 of On.
Minor:
1. Line 106-108, add references.
2. Line 220-221, the accession number of expressed sequence 220 tag (EST) database should be shown in the Methods section.
3. Line 235-236, add references for “OmI and Sg, which are known to segregate for SD on LG1.”.
4. References format should be checked. For example, Ref.78. “LinYan, Z.; YongXiu, Q.” Should be “Zhou, L.; Qiu, Y.”
5. Species names in the reference section should be checked. Species name in all Latin names should be in lowercase, while the first letter of the genus name should be in uppercase.
