FST, a female-specific transcript from the medfly Ceratitis capitata (Diptera: Tephritidae)

We report here the sequence of a novel cDNA clone (FST, female‐specific transcript), isolated by differential screening during a search for sexually mature accessory gland‐specific transcripts from the medfly Ceratitis capitata. It contains an open reading frame (ORF) with a potential translational...

Description
Summary:We report here the sequence of a novel cDNA clone (FST, female‐specific transcript), isolated by differential screening during a search for sexually mature accessory gland‐specific transcripts from the medfly Ceratitis capitata. It contains an open reading frame (ORF) with a potential translational start site encoding a putative precursor peptide of 100 amino acids. The FST gene is expressed only in the female reproductive accessory glands. Like the accessory gland‐specific antibacterial peptides ceratotoxins, its expression reaches the maximum level when sexual maturity is achieved. However, in contrast to ceratotoxins, it is expressed at a basal level in newly emerged females, and its expression does not increase after mating.
