Abstract excerpt
In poplar, we identified proteins homologous to yeast proteins involved in osmosensing multistep phosphorelay Sln1p-Ypd1p-Ssk1p. This finding led us to speculate that Populus cells could sense osmotic stress by a similar mechanism. This study focuses on first and second protagonists of this possible pathway: a histidine-aspartate kinase (HK1), putative osmosensor and histidine phosphotransfer proteins (HPt1 to...
