    1. RNS2 is required for the biogenesis of a wounding responsive 16 nts tsRNA in Arabidopsis thaliana.
      Title: RNS2 is required for the biogenesis of a wounding responsive 16 nts tsRNA in Arabidopsis thaliana.
    2. Lack of rRNA recycling in rns2-2 cells triggers a change in carbon flux, which is redirected through the pentose phosphate pathway to produce ribose-5-phosphate for de novo nucleoside synthesis. rRNA or ribosome turnover is thus essential for cellular homeostasis, probably through maintenance of nucleoside levels as part of the salvage pathway.
