Journal ArticleDOI
Abiotic stress generates ROS that signal expression of anionic glutamate dehydrogenases to form glutamate for proline synthesis in tobacco and grapevine.
Damianos S. Skopelitis,Nikolaos V. Paranychianakis,Konstantinos A. Paschalidis,Eleni D. Pliakonis,Ioannis D. Delis,Dimitris I. Yakoumakis,Antonios Kouvarakis,Anastasia K. Papadakis,Euripides G. Stephanou,Kalliopi A. Roubelakis-Angelakis +9 more
TL;DR: The hypothesis that the salinity-generated ROS signal induces α-G DH subunit expression, and the anionic iso-GDHs assimilate ammonia, acting as antistress enzymes in ammonia detoxification and production of Glu for Pro synthesis, is supported.
Journal ArticleDOI
Spermidine Exodus and Oxidation in the Apoplast Induced by Abiotic Stress Is Responsible for H2O2 Signatures That Direct Tolerance Responses in Tobacco
Panagiotis N. Moschou,Konstantinos A. Paschalidis,Ioannis D. Delis,Athina H. Andriopoulou,George D. Lagiotis,Dimitrios I. Yakoumakis,Kalliopi A. Roubelakis-Angelakis +6 more
TL;DR: Results reveal that salinity induces the exodus of Spd into the apoplast, where it is catabolized by PAO, producing H2O2, which results in the induction of either tolerance responses or PCD, depending also on the levels of intracellular PAs.
Journal ArticleDOI
Transgenic tobacco plants overexpressing polyamine oxidase are not able to cope with oxidative burst generated by abiotic factors.
Panagiotis N. Moschou,Ioannis D. Delis,Konstantinos A. Paschalidis,Kalliopi A. Roubelakis-Angelakis +3 more
TL;DR: Although the higher levels of H( 2)O(2) generated by overexpression of Mpao in the transgenics, with altered PA homeostasis, were successfully controlled by the concomitant activation of the antioxidant machinery, further increase in ROS was detrimental to cellular functions and induced the PCD syndrome.
