RNA Turnover Plays a Role in Ethylene Signaling

Abstract

Recessive ethylene-insensitive mutants known as ein5/ain1 correspond to a gene whose identity has remained elusive for more than 10 years. Potuschak et al. (pages [3047–3057][1]) confirm that EIN5 is allelic XRN4 , which encodes a cytoplasmic exoribonuclease. The authors show that XRN4 is required
