在用一个Pelements转化果蝇M品系后,建立了6个品系,并在4年期间监测了它们的分子和表型特性。所有品系的P元素数均随时间的延长而增加,但各品系的增加速度不同。此外,退化元素出现在每一个线在传播过程中。到第四年年底,每个品系的元素总数与一个非常强的P品系相似。在表型水平上,所有的转化株系都表现出高的磷活性,但只有三个株系具有完全或接近完全的调节能力。其他三条线路在4年期间仅达到中等水平的调节。其中有一行特别值得注意。尽管它每个基因组含有多达55个P元件(其中20个可能是完整的),并且具有极高的P活性潜力,但它仍然表现出有限的调节能力。此外,当该系的雌性保持在高温下时,抑制P活性的能力甚至进一步减弱。具有这种分子和表型特性组合的菌株,在明显稳定的构型中,以前没有描述过。结果进行了讨论的背景下,在regulatingPelement表达的退化元素的可能作用。
Following transformation of aDrosophila melanogastertrue M strain with an autonomousPelement, six lines were established and monitored for their molecular and phenotypic properties during a 4-yr period. The number ofPelements increased with time in all the lines but the rate of increase differed among lines. Furthermore, degenerate elements arose in each of the lines during propagation. By the end of the 4th yr, the total number of elements in every line was similar to that of a very strong P strain.—At the phenotypic level, all of the transformed lines evolved high P activity, but only three developed complete or nearly complete regulatory ability. The other three lines attained only intermediate levels of regulation over the 4-yr period. One of these lines was particularly noteworthy. Although it contained as many as 55Pelements per genome (20 of which were potentially complete) and had extremely high P activity potential, it continued to exhibit limited regulatory ability. In addition, when females of this line were maintained at high temperatures, the ability to suppress P activity was even further diminished. A strain with this combination of molecular and phenotypic properties, in an apparently stable configuration, has not been previously described.—The results are discussed in the context of the possible role of degenerate elements in regulatingPelement expression.
