Drosophila CG11700 may not affect male fecundity-lifespan tradeoff as previously reported.

ABSTRACT: Our recent investigations on the function of Drosophila CG11700 and CG32744 (Ubi-p5E) genes using CRISPR/Cas9 deletion technology could not repeat or confirm the results on CG11700 shown in our previous study, which was based on P-element excision assay (Zhan Z, Ding Y, Zhao R, Zhang Y, Yu H, Zhou Q, Yang S, Xiang H, Wang W. Rapid functional divergence of a newly evolved polyubiquitin gene in Drosophila and its role in the trade-off between male fecundity and lifespan. Mol Biol Evol. 2012:29(5):1407-1416. doi:10.1093/molbev/msr299). Here, by CRISPR/Cas9 editing, we generated mutants of CG32744 with the whole gene body fully deleted from the genome, and truncated mutants of CG11700 with N-terminal 103 aa deleted out of its total 301 aa peptide sequence. We carefully conducted the male fecun
