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...

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, ...

TranscriptomicsIntersystem photosynthetic redox signal in retrograde chloroplast-to-nucleus communication
To analyze the impact of photosynthetic redox signals, light sources with spectral qualities that preferentially excite either Photosystem I (PSI light) or Photosystem II (PSII light) were used. The light sources have been described in (Wagner et al, Planta 2008). Strong reduction signals were induc...

TranscriptomicsGene expression profiling of retrograde PAP-signaling and ABA-signaling mutants in response to ABA treatment
Chloroplast-nuclear retrograde signaling is viewed as a mechanism for inter-organelle communication. Here we show the SAL1-PAP (3′-phosphoadenosine 5′- phosphate) retrograde pathway functions more broadly in guard cells, interacting with abscisic acid (ABA) signaling at least in part via exoribonucl...
