Abstract: | MicroRNAs (miRNAs) are a specialized class of small silencing RNAs that regulate gene expression in eukaryotes. In plants,
miRNAs negatively regulate target mRNAs containing a highly complementary sequence by either mRNA cleavage or translational
repression. As a model plant to study fleshy fruit ripening, miRNA studies in tomato have made great progress recently. MiRNAs
were predicted to be involved in nearly all biological processes in tomato, particularly development, differentiation, and
biotic and abiotic stress responses. Surprisingly, several miRNAs were verified to be involved in tomato fruit ripening and
senescence. Recent studies suggest that miRNAs are related to host-virus interactions, which raises the possibility that miRNAs
can be used as diagnostic markers for response to virus infection in tomato plants. In this review, we summarize our current
knowledge systematically and advance future directions for miRNA research in tomato. |
