Fig. 5: GO term enrichment analyses of DEGs in the four comparisons between spaceflight and ground control samples.

Overrepresentation was determined for genes that exhibited differential expression in response to spaceflight in comparison with their control on ground (P < 0.01 and FC ≥ 5). a Number of genes per gene ontology in WT (sp vs. gr). b Number of genes per gene ontology in gi (sp vs. gr). c Number of genes per gene ontology in 35S:CO (sp vs. gr). d Number of genes per gene ontology in FG (sp vs. gr). The black and white bars indicate the GO terms of the up- and down-regulated genes, respectively. Gene Ontology (GO) enrichment analyses (term type: biological process, FDR P-value < 0.001) were performed using the Goatools (https://github.com/tanghaibao/GOatools). The GO terms with low P values are listed first (from left to right). In cases of identical P values, the term with high enrichment (Ratio in study/Ratio in pop) was ranked first. Red triangles indicate flavone metabolic processes.
