The segment polarity phenotype and the lack of naked cuticle between denticle belts, resulting in a lawn of denticles on the ventral epidermis, characteristic for maternally and zygotically mutant arr² embryos is not modified by Scer\GAL4^da.PU-driven expression of any of the following: sgg^{Scer\UAS.T:Myr-Src64B,T:Ivir\HA1}, sgg^{KK-MI.Scer\UAS.T:Myr-Src64B,T:Ivir\HA1}, or sgg^{Scer\UAS.T:Ivir\HA1}.

The increase in average satellite bouton number at the neuromuscular junction which is seen in nwk² larvae is suppressed if they are also carrying arr^k08131/arr².

(Rodal et al., 2011)

None of the embryos that are mutant for both maternal and zygotic arr² and express Scer\GAL4^prd.RG1>dsh^Scer\UAS.cAa exhibit broad stripes of excess cuticle. Some of the embryos show occasional small patches of naked cuticle within their denticle lawns. Expression of dsh^{DIX.Scer\UAS.T:ctail-arr} in arr² mutants under the control of Scer\GAL4^arm.PS produces embryos with completely naked cuticles.

Recovery of arr² homozygous somatic clones in third instar wing discs (induced at around 60 hours after egg laying) is reduced by the presence of puc^E69/+ (10/25 twinspots vs 21/29 in a wild-type background). puc^Scer\UAS.cMa; Scer\GAL4^αTub84B.PL only partially rescues arr² homozygous somatic clone size in the wing disc: these clones are on average 32% of twin-spot clone size, compared to 17% in the absence of puc^Scer\UAS.cMa. Recovery of arr² M(2)53⁺ homozygous somatic clones in a M(2)53¹/+; arr²/+ background is less than arr⁺; M(2)53⁺ controls in the same background (clone survival assayed in third instar wing discs; induced at around 60 hours after egg laying).

Recovery of arr² homozygous somatic clones in third instar wing discs (induced at around 60 hours after egg laying) is reduced by the presence of puc^E69/+ (10/25 twinspots vs 21/29 in a wild-type background). puc^Scer\UAS.cMa; Scer\GAL4^αTub84B.PL only partially rescues arr² homozygous somatic clone size in the wing disc: These clones are on average 32% of twin-spot clone size, compared to 17% in the absence of puc^Scer\UAS.cMa. BacA\p35^Scer\UAS.cHa; Scer\GAL4^αTub84B.PL only partially rescues arr² homozygous somatic clone size in the wing disc: These clones are on average 56% of twin-spot clone size, compared to 17% in the absence of BacA\p35^Scer\UAS.cHa. Many mutant clone cells sort out below the disc epithelium. Flow cytometry analysis of these mutant clone cells shows an increase in the fraction of cells in G2 at the expense of cells in G1 compared to wild-type control cells. Recovery of arr² M(2)53⁺ homozygous somatic clones in a M(2)53¹/+; arr²/+ background is less than arr⁺; M(2)53⁺ controls in the same background (clone survival assayed in third instar wing discs; induced at around 60 hours after egg laying).

(Giraldez and Cohen, 2003)

Clone size is substantially increased in arr² mutant clones in the wing disc if they are also expressing BacA\p35^Scer\UAS.cHa under the control of Scer\GAL4^αTub84B.PL.

(Johnston and Sanders, 2003)

The periodic character of the cuticles made by sgg^M11; arm⁸ maternal/zygotic double mutant embryos is suppressed by arr²/arr², with the resulting cuticle tending toward denticle cell fates. The loss of naked cuticle in arr²/arr² embryos is partially suppressed by arr::fz2^{arr.intra.Scer\UAS.T:Hsap\MYC}; Scer\GAL4^prd.RG1. Suppression is more robust in more anterior segments.

(Tolwinski et al., 2003)

The notching and loss of margin bristles seen in arr² clones in the wing is not suppressed if fz2^Scer\UAS.cCa is expressed in these flies under the control of Scer\GAL4^Bx-MS1096.

(Wehrli et al., 2000)

Flies expressing wg^GMR.PW have very small eyes consisting almost entirely of pigment cells. arr² clones induced in these eyes show an autonomous rescue of ommatidia.
