Using protein–metabolite interactions to identify novel plant metabolite receptors
Introduction
Metabolic signaling through receptor-metabolite binding is of key importance to a myriad of developmental and environmental transitions which occur during a plant`s life cycle. However, in comparison with those characterized in mammalian and microbial systems, there is a current dearth of identified plant metabolite receptors (Kosmacz et al. ). Much of what is known involves phytohormone receptors. Indeed, what is known about non-hormonal receptors comes by analogy to mammalian and microbial systems. Here we will provide a state-of-the-art review of a selection of key metabolite receptors characterized to date, focusing on (i) energy, carbon, and nitrogen signaling elements that are conserved across the Kingdoms of Life as well as (ii) phytohormone receptors which whilst bearing functional homology to mammalian receptors, are plant-specific. The former will cover sensor proteins and p

Global proteome analyses of phosphorylation and succinylation of barley root proteins in response to phosphate starvation and recovery
Introduction
Proteins play critical roles in essential plant biological processes. Their diversity of functions is regulated by a wide range of posttranslational modifications (PTMs), which are central to the modulation of proteins activity, stability, subcellular localization, and interactions with other functional units (Millar et al., ; Willems et al., ). In recent decades, based on rapid advances in high-throughput mass spectrometry (MS), more than PTMs have been identified in eukaryotic cells. Thousands of PTM sites can now be comprehensively discovered and quantified in a single proteomics experiment (UniProt Consortium, ), including phosphorylation, ubiquitination, sumoylation, glycosylation, acetylation, and succinylation (Willems et al., ). Most PTMs of proteins are dynamic, whereby their formation is dependent on the specific targeting of
