Figure 7From: Knockout of the folate transporter folt-1 causes germline and somatic defects in C. elegansSperm production by folt-1 knockout mutant and folt-1/+ heterozygous males. Sperm numbers within the reproductive tracts were tallied at the adult molt and one hour later. folt-1/+ heterozygous males produced wild-type numbers of sperm, but folt-1 knockout mutants had very few sperm, producing only about 3 per hour.Back to article page
