ProteomicsProteomics identifies ubiquitin-proteasome targets and new roles for chromatin-remodelling in the Arabidopsis response to phosphate starvation
In order to identify new regulators of the phosphate (Pi) starvation signaling pathway in plants, we analyzed variation in the abundance of nuclear-enriched nuclear proteins isolated from Arabidopsis roots that depends on Pi supply. We used 2-D Fluorescence Difference Gel Electrophoresis and MALDI-T...

ProteomicsESCRTIII-associated protein AtALIX mediates high affinity phosphate transporter trafficking to maintain phosphate homeostasis in Arabidopsis
Prior to the release of their cargoes into the vacuolar lumen, sorting endosomes mature into multivesicular bodies (MVB) through the action of ENDOSOMAL COMPLEX REQUIRED FOR TRANSPORT (ESCRT) protein complexes. MVB-mediated sorting of high affinity phosphate transporters (PHT1) to the vacuole limits...

ProteomicsHormone-mediated disassembly and inactivation of a plant E3 ubiquitin ligase complex
Phytohormone abscisic acid (ABA) regulates key aspects of plant development such as seed germination, as well as responses to important environmental stresses, including drought, salinity and cold temperatures. The ABA signaling pathway is tightly controlled by the ubiquitin proteasome system. CULLI...
