OXR2 integrates UV-B photomorphogenic signalling, DNA repair, cell cycle regulation, and phenolic compound accumulation in Arabidopsis thaliana.

Ultraviolet-B radiation has a dual effect on plants, acting both as a developmental cue and a source of genetic stress. Plants must balance growth, DNA repair, cell division, and damage mitigation. Oxidation Resistance (OXR) proteins are evolutionarily conserved, TLDc-domain-containing mitochondrial proteins that link...

Protein-independent regulation by transgene-derived small interfering RNAs rewires endogenous regulatory networks to enhance plant growth, architecture, and drought performance

These findings show that transgene-derived siRNAs act independently of protein function to rewire endogenous regulatory networks, providing a potential strategy to optimize crop architecture and yield.

EMB2217 Is a Mitochondrial PPR‐SMR Protein Required for the Splicing of Multiple Group II Introns During Arabidopsis Development

Pentatricopeptide repeat (PPR) proteins are key regulators of the organellar RNA metabolism in plants. However, the functions of mitochondrial PPR proteins belonging to the subclass of P‐type PPR factors containing the SMR domain remain much less understood. Here, we characterize the EMBRYO DEFECTIVE 2217 (EMB2217/At1g...
