Abstract

Despite its central importance in biomass production and sustainable agriculture, we have little understanding of how plant hormones regulate growth. Recently, we discovered a novel phospholipid- signalling cascade that responds to auxin and cytokinin, the two major growth hormones in plants, and involves phosphatidic acid (PA), 3- phosphoinositide-dependent protein kinase 1 (PDK1) and a protein kinase A (PKA)-like protein. We propose: (1) to genetically delineate the pathway and establish the physiological functions for AtPDK1 and AtPKA2 in Arabidopsis, using RNAi, insertional and dominant negative mutants (2) to study the mechanisms by which AtPDK1 and AtPKA2 are regulated by lipids, protein interactions, phosphorylation and by localisation.
