DESCRIPTION:Plant Science Research Horizons seminar with MSc student Quinn 
 Bazinet. Live on Zoom.\n\nPhytopathogens are responsible for substantial c
 rop losses\, with up to 16% of total global crop yield being lost to plant
  pathogens annually. Biotrophic pathogens siphon nutrients from living pla
 nt cells while necrotrophic pathogens feed on dead plant tissue. In genera
 l\, plant resistance to these different pathogenic strategies involves dif
 ferent phytohormone signaling pathways: resistance to biotrophic pathogens
  is mediated by the salicylic acid pathway while resistance to necrotrophi
 c pathogens is governed by the jasmonic acid and ethylene pathways. How th
 ese defensive pathways will be affected by future atmospheric conditions\,
  such as elevated carbon dioxide (CO2) levels is largely unknown. With cur
 rent estimates showing an approximate doubling of atmospheric CO2 by the e
 nd of the century\, C3 plants will experience changes to metabolic process
 es\, in particular photosynthesis. This may impact plant redox homeostasis
  and the resultant link to defensive phytohormone activation. To understan
 d how increased atmospheric CO2 will impact plant resistance\, a pathogen 
 bioassay will be used to monitor disease progression in the model C3 plant
  Arabidopsis thaliana grown in both ambient and elevated CO2 conditions. A
 s well\, quantitative analysis of defensive phytohormones and marker genes
  associated with the jasmonic acid/ethylene-  and salicylic acid-mediated 
 defense pathways will be conducted. These results will help scientists and
  agronomists prepare for the major shifts in crop production that will acc
 ompany atmospheric CO2 changes.\n\nJoin the Zoom meeting\n
