Journal ArticleDOI
Plant Defense Genes Are Synergistically Induced by Ethylene and Methyl Jasmonate.
Yi Xu,Pi-Fang Linda Chang,Dong Liu,Meena L. Narasimhan,Kashchandra G. Raghothama,Paul M. Hasegawa,Ray A. Bressan +6 more
TL;DR: Combinations of ethylene and methyl jasmonate (E/MeJA) synergistically induced members of both groups 1 and 5 of the pathogenesis-related (PR) superfamily of defense genes, which resulted in a synergistic induction of PR-1b and osmotin (PR-5) mRNA accumulation in tobacco seedlings.
Journal ArticleDOI
Does proline accumulation play an active role in stress-induced growth reduction?
Albino Maggio,Saori Miyazaki,Paola Veronese,Tomomichi Fujita,José I. Ibeas,Barbara Damsz,Meena L. Narasimhan,Paul M. Hasegawa,Robert J. Joly,Ray A. Bressan +9 more
TL;DR: It is shown that the level of proline accumulation and the amount of growth are inversely correlated in cells grown under normal osmotic conditions, and it is proposed that proline and other osmolytes may act as a signaling/regulatory molecule able to activate multiple responses that are part of the adaptation process.
Journal ArticleDOI
Salt causes ion disequilibrium‐induced programmed cell death in yeast and plants
Gyung-Hye Huh,Barbara Damsz,Tracie K. Matsumoto,Muppala P. Reddy,Ana Rus,José I. Ibeas,Meena L. Narasimhan,Ray A. Bressan,Paul M. Hasegawa +8 more
TL;DR: Evidence is presented that salt induces PCD in yeast and plants because of an ionic, rather than osmotic, etiology and both salt-sensitive mutants of yeast and Arabidopsis exhibit substantially more profound PCD symptoms, indicating that salt-induced PCD is mediated by ion disequilibrium.
Journal ArticleDOI
Antifungal activity of tobacco osmotin has specificity and involves plasma membrane permeabilization
Laura R. Abad,Matilde Paino D'Urzo,Dong Liu,Meena L. Narasimhan,Moshe Reuveni,Jian-Kang Zhu,Xiaomu Niu,Narendra Singh,Paul M. Hasegawa,Ray A. Bressan +9 more
TL;DR: Osmotin either induced spore lysis, inhibited spore germination or reduced germling viability in seven fungal species that exhibited some degree of sensitivity in hyphal growth inhibition tests, suggesting that the cell wall may be a component of the mechanism by which osmotin permeabilizes the plasma membrane and kills fungal cells.
Journal ArticleDOI
NaCl Regulation of Plasma Membrane H+-ATPase Gene Expression in a Glycophyte and a Halophyte
TL;DR: NaCl-induced plasma membrane H+-ATPase gene expression in expanded leaves and roots presumably indicates that these organs require increased H-electrochemical potential gradients for the maintenance of plant ion homeostasis for salt adaptation.
