一般来说，昆虫通过蜕皮生长（身体大小的增加）。与此相反，角倍蚜雄性的体型在蜕皮后和随着年龄的增长而变小。为了理解这种罕见现象的分子基础，从1-5日龄雄性产生转录组，并通过加权基因共表达网络分析（WGCNA）分析数据。共得到15个拓扑重叠度不同的模块，其中4个模块与雄鱼体长显著相关（p < 0.05）。京都基因和基因组百科全书（KEGG）富集分析表明，四个模块中的一部分基因可能参与自噬和凋亡。此外，在四个模块中共获得40个枢纽基因，其中8个基因在雄性中的表达量高于其他世代的个体。chinensis。这八个基因与自噬和凋亡有关。我们的研究结果揭示了雄性S.中华绒螯蟹雄体蜕皮后的形态变化，也表明中华绒螯蟹雄体蜕皮后的形态变化。无摄食能力的中华绒螯蟹可能通过自噬和凋亡等方式分解自身物质，为生殖细胞发育等生命活动提供能量。
In general, insects grow (increase in body size) through molting. To the opposite, the body size of the males of the horned gall aphid, Schlechtendalia chinensis, gets smaller after molting and as they age. To understand the molecular bases of this rare phenomenon, transcriptomes were generated from 1–5 days old male and the data were analyzed via a weighted gene co-expression network analysis (WGCNA). A total of 15 partitioned modules with different topological overlaps were obtained, and four modules were identified as highly significant for male body length (p < 0.05). Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis suggested that a portion of genes in the four modules are likely involved in autophagy and apoptosis. In addition, a total of 40 hub genes were obtained in the four modules, and among them eight genes were highly expressed in males compared to individuals of other generations of S. chinensis. These eight genes were associated with autophagy and apoptosis. Our results reveal the unique negative growth phenomenon in male S. chinensis after molting, and also suggest that the male S. chinensis with no ability to feed probably decompose their own substances via autophagy and apoptosis to provide energy for life activities such as germ cell development.
