Abstract excerpt

RNase J (RNJ) is a ribonuclease found in bacteria, archaea, and plant chloroplasts, and plays diverse roles in RNA maturation and stability. Chloroplast RNJ is encoded by the nuclear RNJ locus and is essential for embryo maturation. Arabidopsis or tobacco plants depleted for RNJ accumulate massive amounts of double-stranded RNA (dsRNA), which interferes with translation and causes chlorosis. Land plant RNJ...
