1 Here we report that components of the 5"-3" mRNA decay pathway, DCP5, LSM1-7 and XRN4, contribute to a proper response to a key plant hormone abscisc acid (ABA), albeit in a different manner. alisol B 23-acetate decapping 5 Arabidopsis thaliana
2 Plants lacking DCP5 are more sensitive to ABA during germination, whereas lsm1a lsm1b and xrn4-5 mutants are affected at the early stages of vegetative growth. alisol B 23-acetate decapping 5 Arabidopsis thaliana
3 In addition, we show that DCP5 and LSM1 regulate mRNA stability and act in translational repression of the main components of the early ABA signaling, PYR/PYL ABA receptors and SnRK2s protein kinases. alisol B 23-acetate decapping 5 Arabidopsis thaliana
