Objective:
To identify the key genes promoting the differentiation of melon non-embryogenic callus into embryogenic callus.
Methods:
The transcriptome sequencing analysis was used to analyze the mRNA sequence in embryogenic callus (Z) and non-embryogenic callus (F); transcript mapping, gene expression analysis, cluster analysis, classification analysis and enrichment analysis were then used to detect the differentially expressed genes and enriched pathways.
Results:
The correlation coefficient between sample Z and sample F was 0.929 after transcript mapping. The overall gene expression levels in sample Z were higher as compared with sample F. Furthermore, cluster analysis showed that the expression of genes involved in photosynthesis was increased in sample Z when comparing to F. Besides, the classification of differential Gene Ontology (GO) showed that many metabolic processes were affected with the metabolism enhanced in embryogenic callus. Interestingly, Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis further demonstrated the high metabolic activity and active secondary metabolite formation in the embryogenic callus.
Conclusion:
The genes associated with photosynthesis, metabolic pathways and biosynthesis of secondary metabolites may promote the differentiation of callus into embryogenic callus.
