ProteomicsThe capacity of isoprene emission largely influences the proteome of Arabidopsis plants both under well-watered and water-stress conditions
Isoprene is a small lipophilic molecule synthetized at chloroplast level and released into the atmosphere. Isoprene-emitting plants are believed to be better protected against abiotic stresses (i.e. temperature, oxidative stress, drought). The mechanism of action of isoprene is still under debate. I...

ProteomicsQuantitative phosphoproteomics reveal novel roles of cAMP in plants
3′,5′-cyclic adenosine monophosphate (cAMP) is finally recognized as an essential signaling molecule in plants where cAMP-dependent processes include responses to hormones and environmental stimuli. To better understand the role of cAMP at the systems level, we have undertaken a phosphoproteomic ana...

ProteomicsPerturbation of protein homeostasis brings plastids at the crossroad between repairment and dismantling
The chloroplast proteome is a dynamic mosaic of plastid- and nuclear-encoded proteins, and plastid protein homeostasis is maintained through the balance between de novo protein synthesis and proteolysis. Intracellular communication pathways, including the pastid-to-nucleus retrograde communication, ...

ProteomicsA systems biology-oriented investigation of Arabidopsis retrograde-signaling-defective mutant gun1 reveals the co-expression-based HUBs at the center of plastid development and homeostasis
In the present study we investigated at the system level the proteome obtained from seedlings of Arabidopsis thaliana wild-type Col-0 and gun1-101 and gun1-102 mutant plants treated or not with lincomycin (Lin), a chloroplast translation inhibitor widely used to inhibit chloroplast biogenesis and to...

ProteomicsLabel-free proteomic approach to study the non-lethal effects of silver nanoparticles on a biofilm gut model
Among all the food-related nanoparticles consumed every day, silver nanoparticles (AgNPs),due totheir anti-microbial properties, are one of the most commonly utilized. Despite this, the effects of sub-lethal concentrations of AgNPs, especially on gut biofilms, has been poorly investigated. To addres...
