 .\n\nAbstract: Phloem is the vascular tissue in plants – responsible for
  transporting sugars from source to sink. It is well established that os
 motic currents drive the flow of sap through phloem vessels. The energy 
 cost of phloem transport is primarily in the maintenance of the concentr
 ation gradient driving these osmotic currents. The bioenergetic force be
 hind the loading of sugars and amino acids into phloem is generated by p
 roton gradients at the plasma membrane of specialised phloem-loading cel
 ls. This gradient is maintained by actively pumping protons from the cyt
 osol to the apoplast. This allows cells to use proton-coupled plasma mem
 brane symporters to import sugars up their concentration gradients but d
 own the proton gradient and into the phloem. From there the osmotic curr
 ents carry them to where they are needed within the plant.\n\nDespite it
 s essential role in vascular plant growth\, the specifics of phloem cell
  metabolism remain unclear. Maintaining these concentration gradients is
  likely to be an energy bottleneck in plant growth but there is still un
 certainty in the source and transfer of energy in companion cells. Combi
 ning cell-specific transcriptome data with a computational model of meta
 bolism within phloem cells\, I’ll talk you through my exploration of the
  metabolic interactions between cells to identify the main contributors 
 to this energy bottleneck and the best targets to resolve it and increas
 e plant growth.\n\nTo subscribe to the mailing list for this event serie
