Integrated mRNA and Small RNA Sequencing for Analyzing Leaf Spot Pathogen Didymella segeticola and Its Host, Tea (Camellia sinensis), During Infection.

Leaf spot on tea plants (Camellia sinensis [L.] Kuntze), caused by the fungus Didymella segeticola (Q. Chen) Q. Chen, Crous & L. Cai (syn. Phoma segeticola), negatively affects the productivity and quality of tea leaves in Guizhou Province, China. Although the genome sequence of D. segeticola has been published, no data on the transcriptome or microRNAs (miRNAs) of the pathogen or host during infection are available. Here, we report on the high-quality transcriptome and miRNA sequences of both D. segeticola and tea during infection, using the Illumina HiSeq 4000 or HiSeq 2500 platforms. Comprehensive expression profiling of the fungal pathogen and its host will provide a resource for future research into trait-specific genes of the pathogen and the host as well as on host-pathogen interactions and on disease resistance mechanisms.[Formula: see text] Copyright © 2021 The Author(s).
