Fig. 3From: Enhanced ascomycin production in Streptomyces hygroscopicus var. ascomyceticus by employing polyhydroxybutyrate as an intracellular carbon reservoir and optimizing carbon additionGene ontology enrichment analysis of differentially expressed genes in the strain OphaCfkbU. a The enrichment categories and numbers of the up-regulated genes in strain OphaCfkbU. b The enrichment categories and numbers of the down-regulated genes in strain OphaCfkbU. The Y-axes represent different enrichment categories. The X-axes represent the numbers of genes enriched in the corresponding categories, reflecting the degree of enrichmentBack to article page
