rl1 mutant third instar larvae display an aberrant innervation pattern in abdominal body-wall muscles 13 (M13) and 12 (M12) neuromuscular junctions: ectopic targetting of type III axons to M13 (also observed in heterozygous mutants) as well as premature defasciculation of axon bundles at the boundary between M13 and M12.
rl1 mutant adults display a rough eye phenotype (due to missing photoreceptor cells).
rl1 mutants do not exhibit any NMJ defects.
rl1 homozygotes display a slight deletion of the mid-section of the L4 wing vein that is not fully penetrant, and a weak rough eye phenotype.
Homozygous adults have a rough eye phenotype.
Homozygotes have a mild rough eye phenotype and show loss of wing vein material.
Evoked excitatory junction potentials at neuromuscular junctions are decreased in rl1 homozygous larvae.
Homozygotes have a rough eye phenotype, with fewer rhabdomeres per ommatidium (6.04 +/- 1.09) compared to wild type (6.99 +/- 0.07). The number of cone cells is reduced at the pupal stage compared to wild type and the development of the eye is disordered at the third larval instar.
Homozygotes often have gaps in wing vein 4.
Homozygotes have rolled and frayed wing blades.
Wing vein L4 is thinned or disrupted distal to the posterior crossvein.
Hypersensitivity to oxidative stress (paraquat) and ionising radiation.
rl1 hemizygotes have rough eyes and bent down wings. Sections through the eye reveal a lack of most R7 cells and a reduced number of outer photoreceptor cells. A central portion of the L4 wing vein is missing.
Mutation has no effect on rhohs.sev rough eye phenotype.
viable, RK2. wing edges rolled downward; margins somewhat frayed; L4 interrupted distal to posterior crossvein. Eyes small, dark and rough. Most extreme at 26oC, less extreme above and below that temperature (Lakovaara, 1963). Temperature sensitive period for eye phenotype during larval stages with most sensitive stage about 60 hr after hatching, i.e., at the beginning of the third instar (Hackman and Lakovaara, 1966). Effects of dosage of rl and rl+ on eye pigment deposition investigated by Lakovaara (1966).

Egfrf11, rl1 has wing vein L4 phenotype
The increased concentration of circulating hemocytes characteristic for Graf1/Y mutant third instar larvae is partially suppressible by combination with a single copy of rl1; combination with rl1/rl10 reduces the hemocyte levels in Graf1/Y larvae to below wild-type levels, comparable to those seen in rl1/rl10 single mutants.
The increased frequency of aberrant type III axon innervation patterns in body-wall muscle 13 of third instar larvae single heterozygous for rl1 is further enhanced by heterozygosity for either Cdk23 or Gp93EY06213 but not Gαq1, each of these single heterozygotes on their own also display type III axon targeting defects.
CG11266f07714/+ or Prp19CE162/+ enhance the L4 wing vein deletion and rough eye phenotypes of rl1 homozygotes.
One copy of rl1 suppresses the enhanced lethality seen when flies expressing RetMEN2B.Scer\UAS under the control of Scer\GAL4ptc-559.1 are treated with AD58.
One copy of rl1 further suppresses the rescuing effect of AD57 on the lethality of flies expressing RetMEN2B.Scer\UAS under the control of Scer\GAL4ptc-559.1.
One copy of rl1 has no effect on the viability of flies expressing RetMEN2B.Scer\UAS under the control of Scer\GAL4ptc-559.1 treated with AZD-6244.
One copy of rl1 suppresses the wing pattern and ectopic wing vein phenotypes seen when RetMEN2B.Scer\UAS is expressed under the control of Scer\GAL4C-765.
One copy of rl1 further suppresses the enhanced wing pattern and ectopic wing vein phenotypes seen when flies expressing RetMEN2B.Scer\UAS is expressed under the control of Scer\GAL4C-765 are treated with AD58.

One copy of rl1 has no effect on the rescuing effect of AD80 or AD81 on the lethality of flies expressing RetMEN2B.Scer\UAS under the control of Scer\GAL4ptc-559.1.
The structural defects seen in the neuromuscular junctions (NMJ) of Atg13 homozygous larvae are almost completely suppressed by rl1/rl1 : synaptic density and apposition of pre and post synaptic components are restored and NMJ size is partially restored. Despite the fact that evoked excitatory junction potentials at larval NMJs are decreased in both rl1 homozygous and Atg13 homozygous larvae, this phenotype is not see in rl1 Atg13 double homozygotes.
The accumulation of synaptic material in the axons of of motor neurons in Atg13 homozygous larvae is not suppressed by rl1/rl1.
The rough eye phenotype, irregular ommatidial array and increased photoreceptor cell number caused by expression of Gef26EP388 under the control of Scer\GAL4GMR.PF are strongly suppressed by rl1/+.
The rate of eclosion of rl1/Df(2R)PRF flies at 18oC is nearly halved by the presence of Su(var)205205. The eye and wing defects of surviving adults are enhanced.
rl1 recessively enhances the eye and wing defects associated with the asp1/aspDD3 mutant. The brain neuroblast mitotic index of double mutants with asp1 is generally as for asp1 mutants alone. The rl1; asp1 double mutant also displays an increase in the number of mitotic figures that show lagging chromatids at anaphase, and a low frequency of abnormal mitotic figures where the telomeric ends of chromosomes appear to remain in contact, forming daisy chains. The frequency of aneuploid and polyploid figures is significantly increased compared to asp1 single mutants.
Egfrt1 enhances the bristle, ocellar, wing and limb phenotypes of homozygotes. Bristle hyperplasia, ocellus enlargement and ocellus fusion are enhanced. Wings are notched, wing margins are hairier and have ectopic vein material. Legs are fused and bifurcated.
rl1 partially suppresses the external eye phenotype and photoreceptor degeneration seen when Hsap\ATXN182Q.Scer\UAS is expressed under the control of Scer\GAL4GMR.PF. The progressive impairment of motor performance and reduction in lifespan seen when Hsap\ATXN182Q.Scer\UAS is expressed under the control of Scer\GAL4nrv2.PS are also partially rescued.

Scer\GAL4elav-C155-driven expression of rlScer\UAS.cKa efficiently rescues the ectopic targetting of type III axons to the abdominal body-wall muscle 13 but fails to rescue the premature defasciculation of axons bundles at the boundary between muscles 13 and 12 in rl1 mutant third instar larvae. Scer\GAL4Mef2.PU-controlled expression significantly improves both of these innervation defects.
