Abstract
Using mass spectrometry and bioassays as core tools, this project centres on an unbiased high-throughput metabolomic analysis to identify putative novel signals involved in regulation of shoot branching in two model plant species, pea and Arabidopsis. Our previous work with branching mutants, grafting and hormone analysis has provided persuasive evidence that such long-distance signals exist in addition to auxin and cytokinin. We will focus largely on xylen and phloem saps, the likely conduits for signal transmission between shoot and root. The work will advance overall understanding of branching regulation, providing specific information on functions of branching genes, together with novel insights into hormone homoeostasis in plants.
