Phenotype Characterization Of Sas-7(Or1945) C. Elegans, Chase Reinert
Student Symposium
The ability to form a bipolar spindle is crucial for accurate cell division. In the nematode C. elegans several genes have been described with roles in spindle assembly including sas-7. The centriole is a key organizer of mitotic spindles. The sas-7 protein is a centriole component that regulates centriole duplication, elongation, and assembly. To date, most work on sas-7 was using a conditional non-null allele. In this study, phenotypes associated with the loss-of-function sas-7(or1945) null allele were characterized. Homozygous sas-7(or1945) hermaphrodites have reduced brood sizes with no viable embryos compared to wild-type and heterozygotes. When they do produce embryos, they …
