mutants are defective in vulval epithelial invagination and also have a severe reduction in hermaphrodite fertility. sugars from the cytosol, their site of synthesis, into the lumen of the Golgi apparatus, where they are used as sugar-donor substrates by glycosyltransferases (11). Yeast, and mammalian cell line mutants impaired in the transport of specific nucleotide sugars… Continue reading mutants are defective in vulval epithelial invagination and also have a
