Characterization of miRNAs associated with Botrytis cinerea infection of tomato leaves.

ABSTRACT:

Background

Botrytis cinerea Pers. Fr. is an important pathogen causing stem rot in tomatoes grown indoors for extended periods. MicroRNAs (miRNAs) have been reported as gene expression regulators related to several stress responses and B. cinerea infection in tomato. However, the function of miRNAs in the resistance to B. cinerea remains unclear.

Results

The miRNA expression patterns in tomato in response to B. cinerea stress were investigated by high-throughput sequencing. In total, 143 known miRNAs and seven novel miRNAs were identified and their corresponding expression was detected in mock- and B. cinerea-inoculated leaves. Among those, one novel and 57 known miRNAs were differentially expressed in B. cinerea-infected leaves, and 8 of these were further confirmed by quan
