Detailed Description

Statement

Reference

Expression of Smn^{dsRNA.C.Scer\UAS.WIZ} under the control of Scer\GAL4^Mef2.PR has no effect on flight ability of adult flies, mobility of the third instar larvae or shape of pupae and Scer\GAL4^elav-C155-driven expression does not impair adult viability.

(Lanfranco et al., 2017)

Expression of Smn^{dsRNA.C.Scer\UAS.WIZ} driven by Scer\GAL4^Mef2.PR does not significantly affect flight ability in flies.

(Borg et al., 2015)

Smn^{dsRNA.C.Scer\UAS.WIZ} driven by Scer\GAL4^elav-C155 or Scer\GAL4^VGlut-OK371 (but not Scer\GAL4^ChAT.7.4) disrupts locomotor behavior (significantly reduced distance covered and overall activity, and increased pause number but not pause length in Buridan's assay) in adult flies compared to wild type; when driven by Scer\GAL4^how-24B, the only significant difference compared to wild type is an increase in pause number.

Baseline synaptic transmission measured at the neuromuscular junction (muscle 6/7 in abdominal segment 2) is not significantly altered in third instar larvae with Smn^{dsRNA.C.Scer\UAS.WIZ} driven by Scer\GAL4^elav-C155 : no changes in excitatory junction potential (EJP) amplitude, mini evoked junction potential (mEJP) amplitude or the quantal content of release were detected. However, when Smn^{dsRNA.C.Scer\UAS.WIZ} is driven in muscles by Scer\GAL4^how-24B there are significant decreases in EJP and mEJP amplitude.

(Timmerman and Sanyal, 2012)

Expression of Smn^{dsRNA.C.Scer\UAS.WIZ} driven by Scer\GAL4^how-24B significantly reduces the number of boutons per muscle at the neuromuscular junction of third instar larvae.

(Sen et al., 2011)

Expression of Smn^{dsRNA.C.Scer\UAS.WIZ} under the control of one of Scer\GAL4^Act, Scer\GAL4^elav.PLu or Scer\GAL4^how-24B results in a reduction in bouton number per muscle area at the neuromuscular junction of third instar larvae compared to wild type.

Genetic Interactions

Statement

Reference

Simultaneous expression of Gem3^ΔN.Scer\UAS and Smn^{dsRNA.C.Scer\UAS.WIZ} leads to strongly reduced mobility in third instar larvae and more elongated shape of the puparium with the Scer\GAL4^Mef2.PR driver and to reduced adult viability with Scer\GAL4^elav-C155.

(Lanfranco et al., 2017)

Co-expression of Gem3^ΔN.Scer\UAS and Smn^{dsRNA.C.Scer\UAS.WIZ} driven by Scer\GAL4^Mef2.PR results in flight defects and reduces adult viability, compared to controls.

(Borg et al., 2015)

Co-expression of htl^GD84, stumps^GD10225 or btl^GD14439 enhances pupal lethality in Scer\GAL4^how-24B>Smn^{dsRNA.C.Scer\UAS.WIZ} flies (and vice versa). Presence of sty²²⁶/+ suppresses pupal lethality in Scer\GAL4^how-24B>Smn^{dsRNA.C.Scer\UAS.WIZ} flies.

htl^AB42/+ or btl^dev1/+ significantly enhances (further reduces) the decreased number of boutons per muscle seen in the neuromuscular junction of third instar Scer\GAL4^how-24B>Smn^{dsRNA.C.Scer\UAS.WIZ} larvae.

Co-expression of htl^GD84 enhances (further reduces) the reduced number of boutons per muscle at the neuromuscular junction of in Scer\GAL4^how-24B>Smn^{dsRNA.C.Scer\UAS.WIZ} third instar larvae (and vice versa).

Co-expression of htl^Scer\UAS.cMa rescues the phenotype of reduced bouton number per muscle at the neuromuscular junction of Scer\GAL4^how-24B>Smn^{dsRNA.C.Scer\UAS.WIZ} third instar larvae.

Co-expression of stumps^Scer\UAS.cVa rescues the phenotype of reduced bouton number per muscle at the neuromuscular junction of Scer\GAL4^how-24B>Smn^{dsRNA.C.Scer\UAS.WIZ} third instar larvae to control levels (and vice versa).
