Df(2L)A400/Df(2L)b88h49 animals are viable as larvae and adults, with no morphological or behavioural abnormalities easily detected during routine culture. Df(2L)A400/Df(2L)b88h49 larvae do not have defects in multiple dendritic neuron morphology. The larvae are normal in their response to external touch with an eyelash or single hair and show a normal response to four different odours in an olfactory taxis assay. The larvae are indistinguishable from wild type in their ability to respond to a hot probe (pain assay). Df(2L)A400/Df(2L)b88h49 third instar larvae move with a decreased number of stops or turns compared to wild-type larvae, resulting in an extended straight or slightly arching contour trail and a total contour trail area nearly twice that of wild-type larvae. Crawling speed during a linear locomotion burst is increased in the mutant larvae compared to wild type. The mutant larvae complete a full contraction wave cycle in only 1.11 seconds compared to 1.94 seconds in wild-type larvae, due to a more rapid progression of the contraction wave from posterior to anterior and a significant decrease in the length of the pause period between contraction waves.
Viable in combination with Df(2L)A400.
Df(2L)A400/Df(2L)b88h49 mutant adults do not show any defects in sensing food hardness and like the wild-type flies prefer softer food with lower sugar content (0.5mM sucrose, 0.2% agarose) to a hard food with higher sugar content (1mM sucrose, 2% agarose) in a binary choice assay.
"irradiation" was stated as tentative. "spontaneous" was stated as tentative.
