FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
nrv2unspecified mutant embryos display decreased muscle contractions, a failure to properly inflate their trachea, and abnormal salivary gland morphology.
Septate junction components are mislocalized or dramatically reduced in nrv2unspecified mutant embryos in their trachea, epidermis and salivary glands.
cora2, nrv2[+]/nrv2unspecified has embryonic salivary gland & epithelial cell phenotype
cora1/cora2, nrv2unspecified has embryonic salivary gland & epithelial cell phenotype
cora2, nrv2unspecified has embryonic salivary gland & epithelial cell phenotype
cora1/cora2, nrv2[+]/nrv2unspecified has embryonic salivary gland & epithelial cell phenotype
cora1/cora2 or cora2/cora2 mutant embryos have an effective diffusion barrier in the embryonic salivary glands that is disrupted when nrv2unspecified/+ is present.
