AI Article Synopsis
- Tomato Dicer-like2 (slDCL2) helps plants fight off viruses like potato virus X and tobacco mosaic virus.
- It makes small RNA molecules that help protect the plants and are important for their defense.
- Scientists found that using special RNA can boost these protective molecules, making plants even better at resisting these viruses.
Article Abstract
Tomato Dicer-like2 (slDCL2) is a key component of resistance pathways against potato virus X (PVX) and tobacco mosaic virus (TMV). It is also required for production of endogenous small RNAs, including miR6026 and other noncanonical microRNAs (miRNAs). The 2 mRNAs are targets of these slDCL2-dependent RNAs in a feedback loop that was disrupted by target mimic RNAs of miR6026. In lines expressing these RNAs, there was correspondingly enhanced resistance against PVX and TMV. These findings illustrate a novel miRNA pathway in plants and a crop protection strategy in which miRNA target mimicry elevates expression of defense-related mRNAs.
