Statement
Reference
Imprecise excision of the P{lacW} element, removing the 5' P-element end, the Ecol\lacZ gene and part of the w+mC sequence. The deletion extends from position -2046 in w+mC to position +3101 of H, deleting sequences encoding the first 804 amino acids of the H protein.
Deletion removing two-thirds of the ORF (F. Schweisguth, unpublished observations).
Deletion of about two thirds of the protein coding region.

hide Detailed Description
Statement
Reference
Heterozygotes show a double-socketing phenotype in a few macrochaetae on the notum. Homozygous clones in the adult notum lack external sensory organ structures.
Whereas wild-type intestinal stem cell (ISC) clones proliferate over time, homozygous ISC clones fail to grow, forming either very small groups of cells or remaining as single cells at 14 days after clone induction. Cell fate appears to be affected in the mutant clones; many of the mutant cells appear to have lost ISC characteristics without properly differentiating into enteroblasts when marker expression is analysed at 6 days after clone induction.
Heterozygotes show developmental defects in the macrochaetae (shaft-to-socket conversions or bristle loss).
Mutants show a small amount of wing vein truncation mostly at the tip of wing vein L5.
Heterozygotes have a shortened wing vein L5.
Heterozygotes show a few double socket bristles on the notum.
Heterozygotes have several missing or double socket sensory organs, particularly on the head.
Homozygous clones in the notum are characterised by a loss of bristle phenotype. The ratio between wild-type bristles and wild-type epidermal cells along the clone border is 0.1 (compared to 0.05 for control clones) suggesting that HE31 cells produce a weaker inhibitory signal than wild-type cells. No veins form in the wings of homozygous pharate adults. Double sockets are seen at the position of the stout bristles on the anterior wing margin. Homozygous clones interrupt vein formation in a cell autonomous manner. The ventral nerve cord appears similar to wild-type in stage 14 homozygous embryos. A single socket cell per external sense organ is seen in most positions in homozygous embryos. Occasionally, missing or extra socket cells are seen.
The bristle loss phenotype of H20/HE31 can be suppressed by deleting components of the E(spl)-complex. The degree of suppression depends on both the number and identity of E(spl)-complex transcription units removed. Rescued bristles display a double socket phenotype. Clonal analysis revealed that the gro mutant bristle tufting phenotype is epistatic to the H null bristle loss phenotype.

insv[unspecified] ; H[E31]/+ flies show double socketing of nearly all external sensory organs on the notum. Homozygous H[E31] clones in the adult notum which are also expressing insv[Scer\UAS.cDa] under the control of Scer\GAL4[tub.PU] can develop external sensory organ structures.
H[E31] Su(H)[del47] double mutant intestinal stem cell (ISC) clones show an overproliferation of small ISC-like cells, as occurs in Su(H)[del47] single mutant clones. H[E31] Df(3R)E(spl)δ-6 double mutant intestinal stem cell (ISC) clones show an overproliferation of small ISC-like cells, as occurs in Su(H)[del47] single mutant clones.
In contrast to PsnI2 single mutants, the dorsal/ventral boundary forms correctly in HE31; PsnI2 double mutants.
CtBP87De-10 dominantly enhances the bristle defects seen in HE31/+ flies. This enhancement is almost entirely due to shaft-socket transformations, with only a mild effect on bristle loss. groE73 dominantly enhances the bristle defects seen in HE31/+ flies. Both the shaft-to-socket and bristle loss phenotypes are enhanced.
The shortening of wing vein L5 seen in HE31/+ flies is suppressed by CG6194P0997/+.
apUGO35,HE31 double mutants have large wing pouches with no margin structures.
Double heterozygotes of HE31 with Pros261 or Prosβ21 show strong synergistic enhancement of the double socket bristle and microchaete phenotypes.
pbhs.PB HE31/Ras85De1F triple heterozygotes have deletions of the distal portions of wing veins L4 and L5, up to and including the posterior crossvein. The spacing and position of the campaniform sensilla along the proximo-distal axis of wing vein L3 is altered.
The heterozygous phenotype is enhanced by a single copy of E(spl)K1K2mut or E(spl)K:CAACdel but not by E(spl)tLa.

Germ line clonal analysis indicates that H activity is not essential for embryogenesis.
H20/HE31 is used as the standard null genotype.
Double mutant analysis fails to establish a strict epistatic relationship between H and Su(H) for the specification of sensory organ precursor fate.
