摘要： Cassava (Manihot esculenta Crantz) is an important staple food crop in Latin America and Africa. However, after harvest, the tuberous roots undergo rapid post-harvest physiological deterioration (PPD), a known perishable phenomenon that usually appears within 72 h post-harvest. Post-harvest physiological deterioration largely reduces the quality and economic value of cassava tuberous roots, restricting the use of cassava as a raw material in the food industry. To analyze the regulatory roles of long non-coding RNAs (lncRNAs) during PPD, whole systematic screening of lncRNAs was performed. In this study, 288 differentially expressed lncRNAs were identified from 2,787 high-confidence lncRNAs during PPD. cis-Acting analysis revealed 10 interested lncRNA-mRNA pairs, in which the neighboring protein-coding genes were mainly related to ethylene signaling, calcium sensors, and transcription factors. trans-Regulatory coexpression network analysis reported that lncRNAs were potentially associated with genes involved in the oxidation-reduction process. These results present a broad vision of cassava lncRNAs during PPD and provide the potential candidates for genetic engineering to alleviate deterioration of tuberous roots.
