Characteristics of unigenes and samples. a Distribution of unigene lengths in Magnolia wufengensis. b Species distribution of top BLAST hits for each unigene with a cut-off E-value of 1e− 5. c Functional annotation of unigenes based on Gene Ontology (GO) categorization. d Clusters of Orthologous Group (COG) classification. In total, 59,765 unigenes were assigned COG classifications according to the String database and grouped into 25 COG classifications. e Top 20 KEGG pathways containing the most unigenes. f Correlation analysis between the samples
