SUMMARY:Stomatal evolution and using knowledge of stomatal function to bre
 ed more resilient crops - Professor Alistair Hetherington\, University of 
 Bristol

DESCRIPTION:Stomata are pores found\, typically\, on the surfaces of leave
 s and their acquisition is believed to be one of the key factors leading t
 o the successful radiation of the early terrestrial flora. They are surrou
 nded by two guard cells. In responses to changes in the environment and\, 
 or endogenous signals\, the guard cells increase or decrease in turgor cau
 sing the pore to open or close.  Changes in stomatal aperture result in ch
 anges to transpirational water loss and the uptake of carbon dioxide. Thes
 e in turn\, play out in terms of alterations in dry matter accumulation\, 
 leaf cooling\, nutrient uptake and the ability to withstand reductions in 
 soil water availability.  A complex intracellular signalling network is re
 sponsible for coupling extracellular signals to alterations in guard cell 
 turgor.  This lecture will focus on stomatal evolution where there are sti
 ll many fundamental questions that remain unanswered and also\, if time pe
 rmits\, will discuss recent results that have relevance to developing crop
 s that are more resistant to climate and environment change.  \n\nDue to h
 aving to go online\, we are restricting the talks to University of Cambrid
 ge and alumni to keep them as informal as possible.\n\nContact reception@p
