Hydrogen sulfide promotes lateral root formation in peach through persulfidation of SnRK1α kinase
Plant Biotechnology Journal, EarlyView.Summary Root development is crucial for the growth and yield of horticultural crops. Hydrogen sulfide (H2S), an important gasotransmitter, has been shown to regulate lateral root (LR) formation in plants, including peach (Prunus persica). However, its specific regulatory mechanism remains largely unclear.

Purification and properties of a HeLa cell enzyme able to remove the 5'- terminal protein from poliovirus RNA [PDF]
, 1980 Using a rapid phenol extraction assay, an enzyme was purified from uninfected HeLa cells that can cleave the 5'-terminal protein (VPg) from poliovirus RNA. Both cytoplasmic and nuclear extracts had enzymes with similar behavior.
