Abstract:
Taking C.morifolium ‘Boju’ and C.morifolium ‘Hangju’ as the test materials，the changes of differentially expressed genes and metabolic pathways in C.morifolium ‘Boju’ and C.morifolium ‘Hangju’ during the blooming period under drought stress were investigated by using high-throughput transcriptome sequencing，in order to provide a reference for clarifying the molecular mechanisms of C.morifolium in response to drought stress.The results showed that 28 145 and 4 831 DEGs were identified in C.morifolium ‘Boju’ and C.morifolium ‘Hangju’，respectively，under drought stress，with more DEGs enriched in C.morifolium ‘Boju’.The KEGG metabolic pathway enrichment analysis revealed that the DEGs in C.morifolium ‘Boju’ were mainly enriched in the areas of oxidative phosphorylation，amino acid and nucleotide sugar metabolism，galactose metabolism，cysteine and methionine metabolism，phenylpropanoid biosynthesis，stilbenoid，diarylheptanoid and gingerol biosynthesisand flavonoid biosynthesis，etc.，whereas in C.morifolium ‘Hangju’，DEGs were mainly concentrated in photosynthesis-antenna proteins，alanine，aspartate and glutamate metabolism，phenylpropanoid biosynthesis，stilbenoid，diarylheptanoid and gingerol biosynthesisand flavonoid biosynthesis，etc.Preliminary screening of differentially expressed genes after drought treatment in C.morifolium ‘Boju’ and C.morifolium‘Hangju’ by transcriptome sequencing revealed that C.morifolium ‘Boju’ responded to drought stress mainly by enhancing energy metabolism，amino acid metabolism，and secondary metabolism，while C.morifolium ‘Hangju’ responded to drought mainly by enhancing carbohydrate metabolism，amino acid metabolism，secondary metabolism，and photosynthesis.
