DESCRIPTION:Plants exhibit remarkable developmental plasticity in response
  to changes in nutritional status or the environment. We use the Arabidops
 is stomatal lineage as model to understand how information from a variety 
 of local and distant sources is integrated into developmental decisions. S
 tomata are microscopic cellular valves essential for gas-exchange between 
 the plant and atmosphere. Stomatal guard cells and the developmental pathw
 ays used to make\, pattern and adapt them to the prevailing environment of
 fer a distillation of important themes in development and a platform for s
 ingle-cell investigations of identity and physiology. It is also important
  to forge links between stomatal development and physiology at multiple sc
 ales in diverse plant families. The parallel expansion of stomatal lineage
  complexity and stomatal transcription factors across the plant kingdom pr
 ovides a powerful “natural laboratory” in which to analyze structure/f
 unction of individual proteins and evolution of their regulatory networks.
  I will present vignettes of how we’ve leveraged key regulators of stoma
 tal development into a system-wide view of cell identity\, and preview som
 e of the experimental and imaging-based tools that enable us to capture an
 d manipulate these regulators of developmental decisions in Arabidopsis. W
 ith these tools and the discovery that homologous transcription factors an
 chor cell identities in Arabidopsis\, Physcomitrella and Brachypodium\, we
  are beginning to capture information about cell identity and developmenta
 l potential in a wide range of plants possessing interesting stomatal prop
 erties\, including many plants of ecological and economic relevance.
