Dynamic responses of barley root quantitative succinyl-proteome to short-term phosphate starvation and recovery

Improving phosphate (Pi) acquisition and utilization efficiency is a crucial challenge for the sustainability of agriculture worldwide. The understanding of plant how to response and cope with Pi-limitation, and its underlying molecular mechanisms is key to discovering strategies of efficient Pi acquisition and utilization. Barley (Hordeum vulgare L.) is one of the major cereal crops, has distinct advantage for studying mechanisms of tolerance of phosphorus deficiency due to low Pi demand. Recent studied reveal that post-translational modification (PTM) by phosphorylation, ubiquitination, and glycosylation are play important roles in cellular regulation the plant phosphate starvation response (PSR). Lysine succinylation occurs frequently in the proteins associated with metabolic pathways, which may participate in the regulation of the plant PSR process. However, succinylation precisely modulates the metabolic pathways of proteins in response to PSR in barley remain largely unknown.
