When a plasmid carrying a P-transposable element (derived from Drosophila melanogaster) is injected into young embryos of D. hawaiiensis, the P-element sequence from the plasmid transposes into the germ-line chromosomes. The introduction of this P element into D. hawaiiensis provides an opportunity to study the behavior of the transposable element in a novel context. Germ-line transposition and numerical increase of the P elements are readily detected in D. hawaiiensis. Thus these aspects of P-element function do not require chromosomal or cytoplasmic properties that are unique to D. melanogaster. Since D. hawaiiensis is among those Drosophila that are most distantly related to D. melanogaster, these results suggest that P-element-mediated transformation may function in many species.
当携带P转座元件（源自黑腹果蝇）的质粒被注射到夏威夷果蝇的幼胚中时，质粒中的P元件序列会转座到生殖系染色体中。将这种P元件引入夏威夷果蝇为在新环境中研究转座元件的行为提供了一个机会。在夏威夷果蝇中很容易检测到P元件的生殖系转座和数量增加。因此，P元件功能的这些方面并不需要黑腹果蝇特有的染色体或细胞质特性。由于夏威夷果蝇是与黑腹果蝇亲缘关系最远的果蝇之一，这些结果表明P元件介导的转化可能在许多物种中起作用。
