In addition, when exposed to B. thailandensis, fertile lin-7 (RNAi) nematodes, fertile lin-7 (e1449) mutants as well as sterile lin-7 (e1449) mutants [via cdc-25.1 RNAi (Evans et al., 2008; Shapira and Tan, 2008)] consistently exhibited enhanced survival over wild-type nematodes, indicating that the lin-7-mediated infection phenotype is not related to germline signalling. This evidence concerns the gene LIN7A and infection.
