The Drosophila genus is one of the main model organisms in evolutionary studies, including those investigating the role of transposable elements (TE) in genomic evolution both at the nucleotide and chromosome levels. D. incompta is a species with restricted ecology, using Cestrum (Solanaceae) flowers as unique sources for oviposition, feeding and development. In the present study, we deeply characterise the D. incompta mobilome and generate a curated dataset. A total of 277 elements were identified, corresponding to approximately 14% of the genome, and 164 of these elements are new, of which 32.62% are putatively autonomous and 8.9% are transcriptionally active in adult flies. The restricted ecology does not seem to influence the dynamics of TE in this fly, since the proportion and diversity of TEs in its genome are similar to that of other Drosophila species. This result is reinforced by the absence of a clear pattern when comparing the TE landscape between generalist and specialist flies. Using 32 available Drosophila genomes-24 ecologically generalist species and 8 specialist species-no difference was found between their TE landscape patterns. However, differences were found between species of the Sophophora and Drosophila subgenus, indicating there are lineage-specific factors shaping TE landscapes.

果蝇不育的动植物，是一种繁殖花种：通才和专蝇之间的转座因子景观比较。

果蝇属是进化研究中的主要模型生物之一，包括在核苷酸和染色体水平上研究转座因子（TE）在基因组进化中的作用的那些。D. incompta（D. incompta）是一种生态受到限制的物种，它以C（Solanaceae）的花朵作为产卵，喂养和发育的独特来源。在当前的研究中，我们深刻地描述了D. incompta mobilome，并生成了一个精选的数据集。共鉴定出277个元件，约占基因组的14％，其中164个是新元件，其中32.62％是推定自主的，而8.9％在成年蝇中具有转录活性。受限制的生态似乎并未影响这只苍蝇的TE动力学，因为TEs在其基因组中的比例和多样性与其他果蝇物种相似。比较通才蝇和专蝇之间的TE景观时，由于缺少清晰的图案，从而加强了这一结果。使用32个可用的果蝇基因组，从24个生态学通用物种到8个专业物种，它们的TE景观格局之间没有差异。但是，在Sophophora和Drosophila亚属的物种之间发现了差异，这表明有形成TE景观的特定于谱系的因素。使用32个可用的果蝇基因组，从24个生态学通用物种到8个专业物种，它们的TE景观格局之间没有差异。但是，在Sophophora和Drosophila亚属的物种之间发现了差异，这表明有形成TE景观的特定于谱系的因素。使用32个可用的果蝇基因组，从24个生态学通用物种到8个专业物种，它们的TE景观格局之间没有差异。但是，在Sophophora和Drosophila亚属的物种之间发现了差异，这表明有形成TE景观的特定于谱系的因素。
