It is estimated that th ere are over 100 billion of protein molecules in one single human cell\, an d so are in single plant cells. How such a large cohort of proteins is org anized and managed is key to maintain intracellular proteome homeostasis fo r cell survival. One mechanism required is the timely removal of any outda ted and/or abnormal proteins\, which is primarily done by the ubiquitin (Ub )-26S proteasome system (UPS). To understand the breadth and depth of the UPS functions\, my lab is interested in its switch role in flowering plant development using Arabidopsis thaliana as a model. In this talk\, I will d iscuss our recent studies in 1) transcriptome regulation of UPS members acr oss different developmental stages of Arabidopsis\, 2) development of prote omic approaches to studying the ubiquitylation and Skp1-Cul1-F-box-mediated regulatory proteomes\, 3) establishment of core F-box-controlled developme ntal phenomes\, and 4) fine tuning a reciprocal degradation mechanism betwe en the proteasome and autophagy pathways in seed development. Our studies unraveled several exciting directions in understanding the checkpoint role of protein ubiquitylation and degradation in flowering plant development.
