DESCRIPTION:For decades\, plant electrical signals were thought to be fasc
 inating phenomenon but practically meaningful mostly in carnivorous or sen
 sitive plants. Recent findings indicate\, that plant electrical signals ca
 lled Slow Wave Potentials (SWPs) are crucial for systemic defence activati
 on against herbivorous insects [1]. Currently we have very limited informa
 tion about how these signals propagate and how they are translated to defe
 nce response. Our latest results indicate that two cell types localized in
  vascular tissues are involved in SWPs and calcium wave propagation [2]. M
 oreover\, we found dependent on SWPs\, systemic leaf thickness decreases w
 hich suggests that these signals may induced secondary water fluxes import
 ant for leaf movements [3].\n\n[1] Mousavi et al. 2013. GLUTAMATE RECEPTOR
