Abstract excerpt
Abscisic acid (ABA) plays an essential role in seed germination. In this study, we demonstrate that one SNF1-related protein kinase3-type protein kinase, SOS2-like protein kinase5 (PKS5), is involved in ABA signal transduction via the phosphorylation of an interacting protein, abscisic acid-insensitive5 (ABI5). We found that pks5-3 and pks5-4, two previously identified PKS5 superactive kinase mutants with point...
