alg-3 : alg-4 : gsp-3

"Unlike WT spermatozoa, however, these alg-3/4 spermatozoa never formed pseudopods of normal morphology or polarity, with MSP and GSP-3 localized to the leading edge of the pseudopod (Figure 3B). Instead, we observed that (1) MSP and GSP-3 remained in large punctae that resemble sperm organelles called fibrousbodies (FBs) (5%), (2) MSP localized to the cortex and GSP-3 to the cytoplasm of the spermatid but lacked polarity (3%), or (3) GSP-3 remained in the cytoplasm and spermatids formed a multibranched, spikey pseudopod containing MSP (4%)."

ire-1 : msp-76

msp-76 RNAi in the ire-1(v33) mutant background resulted in a synthetic severe growth defect

alg-3 : alg-4 : gsp-3

"we used immunofluorescence (IF) assays to detect MSP and GSP-3 proteins and fluorescence in situ hybridization (FISH) to detect msp transcripts. Interestingly, IF of MSP and GSP-3, two positively regulated targets, suggested that these proteins were only slightly reduced in alg-3/4 germlines during spermatogenesis and in haploid spermatids at 20C compared to WT (Figure 3A). At 25C, however, MSP and GSP-3 were severely reduced throughout the spermatogenic germline of alg-3/4 males compared toWTand failed to accumulate in spermatids (Figure 3A). Although GSP-3 protein was depleted overall, we found that it also accumulated abnormally in the nuclei of alg-3/4 mutants, particularly at 25C (Figure 3A)."

apr-1 : sys-1

GFP::SYS-1 asymmetry between MSa/MSp and Ea/Ep pairs of sisters was abolished or defective in apr-1(RNAi) embryos.

msp-3 : rmd-3

"we performed FISH on msp-3 transcripts in whole-mounted worms. Under control RNAi conditions, msp-3 becomes expressed in the L4 stage in the most proximal germ cells that undergo spermatogenesis. In young adult and 3-day-old adult worms, msp-3 transcripts are only detected in a handful of residual bodies that remain after the completion of spermatogenesis (Fig. 4A; Table 1). After depleting P granules or csr-1 with RNAi, the domain of msp-3 expression expands past the bend in the gonad in young adults, and in 3-day-old adults can even reach the distal end of the germline. We found that 16% of worms show a distal expansion of msp-3 in young adults following P-granule RNAi, whereas this expansion is observed in 35% of young adults following csr1 RNAi (Fig. 4A; Table 1). Similar distal expansions were observed for the sperm-enriched transcripts ssq-1 and rmd-3 (supplementary material Fig. S4)."
