    Cytology
    Description

    Insertion between the RE and RB alternative 5' UTR exons. The element is inserted such that overexpression from the element using a Scer\GAL4 driver will result in transcription in the same orientation as the orientation of desat1 transcription.

        The total amount of cuticular hydrocarbons is the same in homozygous and control males. The homozygous males 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.

        The total amount of cuticular hydrocarbons is the same in males expressing desat1EpB2 under the control of Scer\GAL4desat1-1573-1 in a desat11573-1/+ background and in control males. The mutant males show a significant decrease in the relative proportions of both linear and methyl branched cuticular hydrocarbons compared to control males.

        The total amount of cuticular hydrocarbons is the same in males expressing desat1EpB2 under the control of Scer\GAL4desat1-1573-C'1 in a desat11573-C'1/+ background and in control males. The mutant males show a significant decrease in the relative proportion of methyl branched cuticular hydrocarbons compared to control males.

        The total amount of cuticular hydrocarbons is the same in homozygous and control females. The homozygous females show a significant decrease in the relative proportion of desaturated cuticular hydrocarbons and a significant increase in the relative proportions of both linear and methyl branched cuticular hydrocarbons compared to control females.

        Females expressing desat1EpB2 under the control of Scer\GAL4desat1-1573-1 in a desat11573-1/+ background show a decrease in the total amount of cuticular hydrocarbons compared to control females. The mutant females show a significant decrease in the relative proportions of linear cuticular hydrocarbons and a significant increase in the relative proportion of desaturated cuticular hydrocarbons compared to control females.

        The total amount of cuticular hydrocarbons is the same in females expressing desat1EpB2 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 linear cuticular hydrocarbons and a significant increase in the relative proportion of desaturated cuticular hydrocarbons compared to control females.

        Males expressing desat1EpB2 under the control of Scer\GAL4desat1-1573-1 in a desat11573-1/+ background do not discriminate between male and female control flies in a courtship assay.

        Males expressing desat1EpB2 under the control of Scer\GAL4desat1-1573-C'1 in a desat11573-C'1/+ background do not discriminate between male and female control flies in a courtship assay.

        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.
