摘要

Pieris rapae is a serious pest of brassicas worldwide. We performed de novo assembly of P. rapae transcriptome by next-generation sequencing and assembled approximately 65,727,422 clean paired-end reads into 32,118 unigenes, of which 13,585 were mapped to 255 pathways in the KEGG database. A total of 6173 novel transcripts were identified from reads directly mapped to P. rapae genome. Additionally, 1490 SSRs, 301,377 SNPs, and 29,284 InDels were identified as potential molecular markers to explore polymorphism within P. rapae populations. We screened and mapped 36 transcripts related to OBP, CSP, SNMP, PBAN, and OR. We analyzed the expression profiles of 7 selected genes involved in pheromone transport and degradation by quantitative real-time PCR; these genes are sex-specific and differentially expressed in the developmental stages. Overall, the comprehensive transcriptome resources described in this study could help understand and identify molecular targets particularly reproduction-related genes for developing effective P. rapae management tools.

Rapae基因组的读数中鉴定了总共6173个新的转录物。此外,1490SSR,301,377个SNP和29,284个诱导鉴定为潜在的分子标记,以探讨P. Rapae群体内的多态性。我们浏览和映射了与OBP,CSP,SNMP,PBAN相关的36名转录物,或。我们分析了涉及信息素转运的7种所选基因的表达谱,通过定量实时PCR降解;这些基因是在发育阶段的性别特异性和差异表达。总体而言,本研究中描述的综合转录组资源可以有助于理解和鉴定分子靶标,特别是用于开发有效的P. Rapae管理工具的生殖相关基因。
