Integrated transcriptomic and metabolomic analyses provide insights into defense against Colletotrichum fructicola in octoploid strawberries.

ABSTRACT:

Background

The Colletotrichum fructicola (C. fructicola) is a hemibiotrophic fungus, which causes devastating anthracnose in strawberry. At present, the resistance mechanism to C. fructicola remains poorly understood.

Results

Here, we used RNA-sequencing and liquid chromatography-mass spectrometry (LC-MS) metabolomics to excavate the molecular mechanism of strawberry resistance to C. fructicola. The differentially accumulated metabolites (DAMs) and differentially expressed genes (DEGs) were screened at different stages after C. fructicola infection in the susceptible 'Benihoppe' and resistant cultivar 'Sweet Charlie'. The core common DEGs with high association of common DAMs were identified by multi-omics integration analysis, and showed convergence and divergence in the two
