    Cytology
    Description

    Insertion in desat1, upstream of the coding sequence. The element is inserted such that overexpression from the element using a Scer\GAL4 driver will result in transcription in anti-sense orientation relative to the orientation of desat1 transcription.

        Homozygous males show an increase in the total amount of cuticular hydrocarbons compared to control males. They show a significant decrease in the relative proportion of desaturated cuticular hydrocarbons and a significant increase in the relative proportion of linear cuticular hydrocarbons compared to control males.

        Males expressing desat1Epd under the control of Scer\GAL4desat1-1573-1 in a desat11573-1/+ background show an increase in the total amount of cuticular hydrocarbons compared to control males. The mutant males show a significant decrease in the relative proportions of both desaturated and methyl branched cuticular hydrocarbons and a significant increase in the relative proportion of linear cuticular hydrocarbons compared to control males.

        Males expressing desat1Epd under the control of Scer\GAL4desat1-1573-C'1 in a desat11573-C'1/+ background show an increase in the total amount of cuticular hydrocarbons compared to control males. The mutant males show a significant decrease in the relative proportions of both desaturated and methyl branched cuticular hydrocarbons and a significant increase in the relative proportion of linear cuticular hydrocarbons compared to control males.

        Homozygous females show an increase in the total amount of cuticular hydrocarbons compared to control females. They show a significant decrease in the relative proportions of both desaturated and methyl branched cuticular hydrocarbons and a significant increase in the relative proportion of linear cuticular hydrocarbons compared to control females.

        Females expressing desat1Epd under the control of Scer\GAL4desat1-1573-1 in a desat11573-1/+ background show an increase in the total amount of cuticular hydrocarbons compared to control females. The mutant females show a significant decrease in the relative proportions of both desaturated and methyl branched cuticular hydrocarbons and a significant increase in the relative proportion of linear cuticular hydrocarbons compared to control females.

        The total amount of cuticular hydrocarbons is the same in females expressing desat1Epd under the control of Scer\GAL4desat1-1573-C'1 in a desat11573-C'1/+ background and in control females. The mutant females show a significant decrease in the relative proportions of both desaturated and methyl branched cuticular hydrocarbons and a significant increase in the relative proportion of linear cuticular hydrocarbons compared to control females.

        Males expressing desat1Epd under the control of Scer\GAL4desat1-1573-1 in a desat11573-1/+ background show a normally high ability to discriminate between male and female control flies in a courtship assay, having a significantly higher courtship index towards females than towards males.

        Homozygous males show a normally high ability to discriminate between male and female control flies in a courtship assay, having a significantly higher courtship index towards females than towards males.
