  • This, combined with the high molar concentrations of these phosphatases found in some cells, makes it sometimes difficult to identify their relative contribution to the dephosphorylation of specific substrates in intact cells through the use of these inhibitors. (sigmaaldrich.com)

  • The results show that ABI1 inhibits not only the ABA-activated SnRK2s but also at least one ABA-non-activated SnRK2, suggesting that the phosphatase is involved in the cross talk between ABA-dependent and ABA-independent stress signaling pathways in plants. (upv.es)
