Abstract

A screen of random, autosomal, homozygous-viable P-element insertions in D. melanogaster found small effects on wing shape in 11 of 50 lines. The effects were due to single insertions and remained stable and significant for over 5 years, in repeated, high-resolution measurements. All 11 insertions were within or near protein-coding transcription units, none of which were previously known to affect wing shape. Many sites in the genome can affect wing shape.

摘要

对黑腹果蝇中随机、常染色体、纯合存活的P因子插入进行筛选,发现50个品系中有11个品系的翅形受到微小影响。这些影响是由单个插入引起的,并且在重复的高分辨率测量中,5年多来一直保持稳定且显著。所有11个插入都在蛋白质编码转录单元内或附近,其中没有一个先前已知会影响翅形。基因组中的许多位点都能影响翅形。
