Fig 5. GO enrichment analysis of DE circRNAs and comparisons between circRNA expression patterns and their circRNA-host genes.

(A) GO enrichment analysis of circRNA-host genes of DE circRNAs in response to LP stress. The red and green boxes highlight the gene clusters involved in response to abiotic stress and LP stress, respectively. (B) Similar expression patterns of circRNAs and their circRNA-host genes were defined as “positive”. In detail, if the expression of a circRNA and that of its circRNA-host gene are both upregulated and downregulated after LP stress, the pattern was defined as “positive”; if not, “negative”.
