| Abstract: | Male accessory gland in Drosophila is a secretory tissue of the reproductive system. The proteins synthesized in the accessory gland are tissue specific, stage specific-seen only during the adult stage and sex specific in the sense of male limited express ion. These secretions that form a component of the seminal fluid are transferred to the female at the time of copulation and play an important role in reproduction. In conj unction with sperm, these secretory proteins assure reproductive success by reducing the female's receptivity to mating and escalating the rate of egg laying. Some of these proteins are antibacterial in nature with a likely function of protecting the female's genital tract against microbial infection during/after mating. Most of the genes involved in the synthesis of acccssory gland protein s are autosomal but a few are still X-linked. Their male specific expression is achieved at the time of sex determination. The level of expression of these genesis dose dependent and they follow Mendelian pattern of segregation. Further, majority of these proteins are rapidly evolving with high rates of non-synonymous substitutions. In this review, by considering the work carried out in different fields , we have tried to generate a comprehensive picture about the male accessory gland and the role of its proteins in the reproduction of Drosophila. |
