SUMMARY:Do plants feel pain?\, Chaos & Complex Systems Seminar\, Simon
  Gilroy\, UW Department of Biology
DESCRIPTION:When an animal is wounded\, a combination of nerve action 
 supported by neurotransmitters rapidly transmits this information thro
 ughout the organism. Similarly\, in response to herbivory of one leaf\
 , plants trigger pre-emptive defenses in unwounded tissues but in this
  case there is no nervous system to propagate the information about da
 mage. Using Arabidopsis plants expressing genetically-encoded bio-prob
 es we have visualized the plant-wide dynamics of changes in cellular C
 a2+ that trigger system-wide responses to wounding. These rapid (withi
 n seconds)\, long-range (throughout the plant body) changes are disrup
 ted in mutants in the genes for the plant glutamate like receptor chan
 nels\, homologs of the glutamate receptor channels of the mammalian ne
 rvous system. The  patterns of wound signaling can be mimicked by appl
 ication of the amino acid glutamate (a classic mammalian neurotransmit
 ter). These results suggest that a plant-wide Ca2+ signaling network a
 cts to communicate information about damage throughout the plant body 
 and although plants lack a nervous system\, glutamate and glutamate re
 ceptor-like channels lie at the core of this long-range plant signalin
 g network.
