Description:About the Seminar:\n\nClimate change and human activity have ma
 de biotic and abiotic plant stressors more common which leads to billions 
 of dollars lost each year as crop yields decline. Fluorescence spectroscop
 y and imaging have been used over the past few decades that aid in identif
 ying when plants are stressed but these methods provide little information
  on what is occurring within stressed plants on the cellular level. Fluore
 scence lifetime is an alternative measurement that yields information abou
 t changes in plant fluorophore environment and can be a comprehensive\, qu
 antitative approach to understanding plant stress. Fluorescence lifetime c
 oupled with microscopy\, also known as fluorescence lifetime imaging micro
 scopy (FLIM)\, can compare fluorophore environments between different plan
 t cells. Recently\, Lei et al. were the first to report FLIM to quantify t
 he extent of stress-related damage in virus infected plant cells. Their re
 sults indicate heterogeneity in intracellular and intercellular fluorophor
 e environment for healthy and virus infected plant cells. The implications
  of these results and FLIM’s potential to be used in the study of plant 
 stress will be discussed in this talk. 4:00 pm
