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.
In egg chambers with tldunspecified follicle cell clones, 88% of chorions have a small operculum, while 12% have short or altered appendages.
Embryos from mothers carrying tldunspecified clones show expanded denticle belts; 76% are ventralized and 24% are dorsalized.
Embryos exhibit dorsal/ventral polarity defects.
tldunspecified mutant embryos are partially ventralised. The cephalic furrow is shifted dorsally and there are defects in germband extension. Denticle belts are extended laterally. No maternal effect is seen in pole cell transplantation experiments.
tldunspecified has phenotype, suppressible by sogP129D
tldunspecified is rescued by tld+t19
tldunspecified is rescued by tld+t12
19 mutants are isolated.
