Comments

FLP-mediated recombination between the two progenitor insertions has resulted in the deletion of the genomic sequence between them.

In combination with other aberrations

Df(1)frqdel3/Df(1)frqdel1 third instar larval mutants do not show any significant difference in resting Ca[2+] level compared to controls.

(Dason et al., 2009)

Df(1)frqdel3/Df(1)frqdel1 third instar larval mutants exhibit more severe defects in quantal release in low-Ca[2+] saline (65% reduction) than in high-Ca[2+] saline (35% reduction).

(Dason et al., 2009)

Nerve-terminals of Df(1)frqdel3/Df(1)frqdel1 third instar larvae show significantly more 1s boutons than in wild-type. The number of 1s and 1b boutons is not different in Df(1)frqdel1 mutants compared to wild-type. Nerve-evoked compound EJPs are significantly smaller than for controls. The frequency and amplitude of spontaneous release are not affected in Df(1)frqdel3/Df(1)frqdel1 lines.

(Dason et al., 2009)

Peak amplitudes of Ca[2+] signals are significantly reduced by 15% on average in Df(1)frqdel3/Df(1)frqdel1 third instar larval mutants compared to controls.
