OsFKBP20-1b stabilizes OsUPF1 and OsUPF2 to promote the degradation of aberrant mRNAs during dehydration stress.

Abstract excerpt

The selective degradation of aberrant mRNAs plays a vital role in ensuring cellular survival under stress conditions. Here, we investigated the role of OsFKBP20-1b, a splicing factor, in dehydration stress response in rice (Oryza sativa). We show that OsFKBP20-1b associates with the core nonsense-mediated mRNA decay (NMD) components, UP-FRAMESHIFT1 (OsUPF1) and OsUPF2, enhances their stability, thereby supporting...
