DESCRIPTION:Fossils indicate microscopic stomatal pores created by guard c
 ells arose in land plants over 410 million years ago and offer clues to th
 eir biomechanical properties.  In this talk I will present a dispatch from
  the ‘frontline’ on recent developments in our understanding of the mo
 lecular genetic toolkits that control stomatal development and regulate gu
 ard cell responses to environmental cues in the moss Physcomitrella\, as t
 he most basal land plant lineage with stomata.  Recent findings provide co
 mplementary information to that recovered from fossils on the possible mec
 hanisms early land plants adopted to produce stomata and regulate their ap
 erture responses to changing environmental conditions.
