Journal ArticleDOI
Identification of Arabidopsis salt and osmotic stress responsive proteins using two‐dimensional difference gel electrophoresis and mass spectrometry
TL;DR: It is demonstrated that NaCl causes a transient suppression of de novo protein synthesis, from which the cells recover within 4 h, which is a typical response of plant cells to salt and hyperosmotic stress.
Journal ArticleDOI
Proteomic analysis of the Arabidopsis thaliana cell wall.
Stephen Chivasa,Bongani K. Ndimba,William J. Simon,Duncan Robertson,Xiao-Lan Yu,J. Paul Knox,Paul G. Bolwell,Antoni R. Slabas +7 more
TL;DR: Evidence for new proteins of unknown function whose existence had been predicted from genomic sequences are reported and an unexpected presence in the cell wall preparations of proteins whose known biochemical activity has never been associated with this compartment hitherto is observed.
Journal ArticleDOI
Salicylic Acid Interferes with Tobacco Mosaic Virus Replication via a Novel Salicylhydroxamic Acid-Sensitive Mechanism.
TL;DR: Pretreatment of tobacco mosaic virus-susceptible (nn genotype) tobacco tissue with SA reduced the levels of viral RNAs and viral coat protein accumulating after inoculation with TMV, suggesting that SA treatment interferes withTMV replication.
Journal ArticleDOI
Plant extracellular ATP signalling by plasma membrane NADPH oxidase and Ca2+ channels.
Vadim Demidchik,Zhonglin Shang,Ryoung Shin,Elinor Thompson,Lourdes Rubio,Anuphon Laohavisit,Jennifer C. Mortimer,Stephen Chivasa,Antoni R. Slabas,Beverley J. Glover,Daniel P. Schachtman,Sergey Shabala,Julia M. Davies +12 more
TL;DR: This study shows that higher plants, although bereft of purinoceptor homologues, could have evolved a distinct mechanism to transduce the ATP signal at the plasma membrane.
Journal ArticleDOI
Extracellular ATP Functions as an Endogenous External Metabolite Regulating Plant Cell Viability
TL;DR: It is shown that extracellular ATP is essential for maintaining plant cell viability and that some forms of pathogen-induced cell death are mediated by the depletion of extraceocytes, suggesting that ext racellular ATP suppresses a default death pathway in plants.
