Description

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.

Phenotypic Data

Phenotypic Class

abnormal neuroanatomy | larval stage | somatic clone

(Komori et al., 2014)

Phenotype Manifest In

gonad | precursor

(Moore et al., 1998)

type II neuroblast | larval stage | somatic clone

(Komori et al., 2014)

type I neuroblast | ectopic | larval stage | somatic clone

(Komori et al., 2014)

Detailed Description

Statement

Reference

Type I neuroblasts in homozygous clones in larval brains retain their functional identity (as assayed by expression of cell fate markers). However, mutant type II neuroblasts in the homozygous clones adopt a type I neuroblast identity and directly generate ganglion mother cells.

(Komori et al., 2014)

Many germ cells are able to coalesce along with gonadal mesoderm to form a gonad; however, some germ cells are excluded from this gonad, presumably due to the reduction in number of somatic gonadal precursors (SGPs). These 'lost' germ cells remain in an area ventral and posterior to the gonad until after coalescence.

Additional Comments

Genetic Interactions

Statement

Reference

trx^unspecified suppresses the supernumerary type II neuroblast phenotype seen in erm^unspecified type II neuroblast clones in the larval brain, and the number of GMCs and neurons is significantly increased in the double mutant clone.

trx^unspecified suppresses the supernumerary type II neuroblast phenotype seen in brat^unspecified type II neuroblast clones in the larval brain, and the number of GMCs and neurons is significantly increased in the double mutant clone.

trx^unspecified pros¹⁷ double mutant type II neuroblast clones form supernumerary type I neuroblasts.

Expression of btd^{Scer\UAS.T:Ivir\HA1} using a Scer\GAL4 driver in trx^unspecified type II neuroblast clones in the larval brain restores the ability of the type II neuroblasts to generate intermediate neural progenitors.

(Komori et al., 2014)

The wing defects caused by simultaneous expression of two copies of esc^{dsRNA.Scer\UAS} and escl^{dsRNA.Scer\UAS} under the control of Scer\GAL4^Bx-MS1096 are completely suppressed by trx^unspecified/+.

(Ohno et al., 2008)

trx^unspecified does not enhance the eye tumour phenotype of flies expressing Dl^Scer\UAS.cDa under the control of Scer\GAL4^ey.PH and also carrying the P{GSV1}lola^GS88A8 insertion (which results in the lola^GS88A8 and psq^GS88A8 alleles being expressed under the control of Scer\GAL4^ey.PH).

(Ferres-Marco et al., 2006)

The addition of heterozygous, trx^unspecified to lolal^k02512/+ animals shows enhancement or suppression.

(Mishra et al., 2003)

The lethality caused by sev^{S11.T:Hsap\MYC} in combination with Ras85D^V12.sev is suppressed by trx^unspecified.
