Title	To invesigate the role of autophagy in Arabidopsis root cellular protein turnover and proteostasis
Description	Protein turnover analysis using partial 15N labelling and protein abundance analysis using 15N spike-in were coupled to investiage the role of autophagy in protein degradation and proteostasis. Our findings show that dysfuncional autophagy due to loss-of-function autophagy components ATG5 and 11 lead to accumulation of protein targets with/without starvation stress. Further protein turnover analysis uncover a subgroup of proteins with retarded degradation. New selective autophagy protein targets involving glycolytic proteins were uncovered by this strategy. Furthermore, we found plasma membrane and cytoskeleton proteins show a general reduction, supporting the cross-interaction between autopahgy and vesicle trafficking pathway. Metabolomics changes in autophagy mutants due to a changed proteostasis was further investigated.
