title: Genetic control of susceptibility to hydroxyproline in Drosophila.
abstract: Hydroxyproline (OHP) is known to produce morphological abnormalities in susceptible Drosophila. In some, OHP prevents head eversion during pupation producing a cryptocephal (crc) phenocopy, others fail to fully stretch legs and wings producing a shortened distance between these appendages (LWD). In this paper the genetic basis of susceptibility to OHP is explored and compared to the control of susceptibility to glucosamine (GA) which also produces a crc phenocopy. The data suggest that genes providing resistance to the effects of GA are different from those conferring resistance to OHP. Furthermore, genes providing resistance to the crc effects of OHP appear to be different from those controlling resistance-to the LWD effects. Intrastrain gene coadaptation also seems to be important in resistance to OHP. The relevance of these results to the problem of the genetic control of developmental buffering is briefly discussed.
