Biphasic ethylene production during the hypersensitive response in Arabidopsis: A window into defence priming mechanisms?

Lloyd, Amanda J.; Hall, Michael A.; Cristescu, Simon M.; Mur, Luis A. J.; Harren, Frans J. M.; Smith, Aileen (2008-09-01)

The hypersensitive response (HR) is a cell death phenomenon associated with localised resistance to pathogens. Biphasic patterns in the generation of H2O2, salicylic acid and ethylene have been observed in tobacco during ...
Biphasic ethylene production during the hypersensitive response in Arabidopsis: A window into defence priming mechanisms?

Mur, L. A. J.; Lloyd, A. J.; Cristescu, Simona M.; Harren, Frans J. M.; Hall, Michael; Smith, Aileen (2008-09-17)
Biphasic ethylene production during the hypersensitive response in Arabidopsis: A window into defence priming mechanisms?

Mur, L. A. J.; Lloyd, A. J.; Cristescu, Simona M.; Harren, Frans J. M.; Hall, Michael; Smith, Aileen (2008-09-17)
Haemoglobin modulates NO emission and hyponasty under hypoxia-related stress in Arabidopsis thaliana

Hebelstrup, Kim H; van Zanten, Martijn; Mandon, Julien; Voesenek, Laurentius A. C. J.; Harren, Frans J. M.; Cristescu, Simona M.; Møller, Ian M.; Mur, Luis A J (2012)

Nitric oxide (NO) and ethylene are signalling molecules that are synthesized in response to oxygen depletion. Non-symbiotic plant haemoglobins (Hbs) have been demonstrated to act in roots under oxygen depletion to scavenge ...
Haemoglobin modulates salicylate and jasmonate/ethylene-mediated resistance mechanisms against pathogens

Mur, Luis A J; Sivakumaran, Anushen; Mandon, Julien; Cristescu, Simona M.; Harren, Frans J. M.; Hebelstrup, Kim H. (2012-05-28)

Nitric oxide (NO) plays a role in defence against hemibiotrophic pathogens mediated by salicylate (SA) and also necrotrophic pathogens influenced by jasmonate/ethylene (JA/Et). This study examined how NO-oxidizing haemoglobins ...
Jasmonates interact with salicylic acid to confer basal thermotolerance in Arabidopsis thaliana

Clarke, Shannon M.; Cristescu, Simona M.; Miersch, Otto; Harren, Frans J. M.; Wasternack, Claus; Mur, L. A. J. (2009-04)

The cpr5-1 Arabidopsis thaliana mutant exhibits constitutive activation of salicylic acid (SA), jasmonic acid (JA) and ethylene (ET) signalling pathways and displays enhanced tolerance of heat stress (HS). cpr5-1 crossed ...
Laser photoacoustic detection allows in planta detection of nitric oxide in tobacco following challenge with avirulent and virulent pseudomonas syringae pathovars

Harren, Frans J. M.; Smith, Aileen R.; Laarhoven, Lucas J. J.; Holton, Nicholas J.; Mur, Luis A. J.; Santosa, I. Edi (2005-07-01)

We demonstrate the use of laser photoacoustic detection (LPAD) as a highly sensitive method to detect in planta nitric oxide (.NO) production from tobacco (Nicotiana tabacum). LPAD calibration against .NO gas demonstrated ...
Metabolomic approaches indicate that cell wall modifications play a major role in ethylene-mediated resistance against Botrytis cinerea

Lloyd, A. J.; Allwood, J. William; Winder, Catherine L.; Dunn, Warwick B.; Heald, J. K.; Cristescu, Simona M.; Sivakumaran, A.; Harren, Frans J. M.; Mulema, Joseph; Denby, Katherine; Goodacre, Royston; Smith, A. R.; Mur, L. A. J. (2011-09)

In Arabidopsis, resistance to the necrotrophic fungus Botrytis cinerea is conferred by ethylene via poorly understood mechanisms. Metabolomic approaches compared the responses of the wild-type, the ethylene-insensitive ...
Nitric oxide in plants an assessment of the current state of knowledge

Mur, Luis A. J.; Mandon, Julien; Persijn, Stefan; Cristescu, Simona M.; Moshkov, Igor E.; Novikova, Galina V.; Hall, Michael A.; Harren, Frans J. M.; Hebelstrup, Kim H; Gupta, Kapuganti J (2013)

BACKGROUND AND AIMS: After a series of seminal works during the last decade of the 20th century, nitric oxide (NO) is now firmly placed in the pantheon of plant signals. Nitric oxide acts in plant-microbe interactions, ...
Nitric oxide interacts with salicylate to regulate biphasic ethylene production during the hypersensitive response

Hall, Michael A.; Laarhoven, Lucas J. J.; Harren, Frans J. M.; Mur, Luis A. J.; Smith, Aileen R. (2008-09-17)

C2H4 is associated with plant defense, but its role during the hypersensitive response (HR) remains largely uncharacterized. C2H4 production in tobacco (Nicotiana tabacum) following inoculation with HR-eliciting Pseudomonas ...
NO provides mainly avr-dependent inputs into cell death mechanisms associated with the hypersensitive response in tobacco

Harren, Frans J. M.; Mur, Luis A. J.; Kenton, Paul; Smith, A.; Laarhoven, L. (2007-04)

The hypersensitive response (HR) is a localised programmed cell death that can aid in neutralising infections by pathogens. H2O2 and NO are proposed elicitors of the HR and we have employed in planta assays to measure the ...
