Abstract excerpt

DXO1, the only DXO homolog in Arabidopsis, due to its plant-specific features, exhibits strong deNADding enzymatic activity but has no apparent role in 5' QC. Despite its important contribution to plant RNA metabolism, the direct impact of DXO1 enzymatic activity on cellular processes appears surprisingly limited. Notably, most molecular and morphological changes observed so far in dxo1 mutant plants depended on...
