ObSheesh #1: Yes, of course. Almost from the Beginning of P Factor Transformation (that's 1982, for the younguns), inter-species genetic transformations were done. This was interesting & important in connection with the odd discontinuities in the species-subgroup distributions of naturally occurring P family members. Two early examples of published embryo microinjection transfers of cloned-melanogaster-P into other Drosophila species include Scavarda & Hartl's work with D. simulans and Brennan et al.'s work with Hawaiian Drosophila species. The latter laid the foundation for neat inter-species studies on the evolution of regulatory elements controlling Adh expression. I'm sure there are many other relevant studies by these & other investigators, and not necessarily limited to putting melanogaster-P into other species. >Also, can anyone direct me to a reference with data on heterochromatin >content in D. mauritiana? ObSheesh #2: Try searching the FlyBase references database. Mark -- Mark D. Garfinkel My views are my own, which is why they're copyright 1995 (c) .
