Expression of POS-1 in the maternal germline causes sterility in the next generation
The image shows multiple C. elegans young adult hermaphrodites with a 3ʹUTR deletion mutation in the pos-1 gene. POS-1 protein is colored in cyan and PGL-1 protein is colored in purple. One worm in the middle of the field appears to lack both POS-1 and PGL-1. This animal displays the partially penetrant sterility phenotype caused by failure to maintain the germline in the pos-1 3ʹUTR deletion mutation. Varderesian et al. 2026
