Phosphorylation-mediated signalling in flowering: prospects and retrospects of phosphoproteomics in crops

Mohammad Arefian et al. Biol Rev Camb Philos Soc. 2021 Oct.

Abstract

Protein phosphorylation is a major post-translational modification, regulating protein function, stability, and subcellular localization. To date, annotated phosphorylation data are available mainly for model organisms and humans, despite the economic importance of crop species and their large kinomes. Our understanding of the phospho-regulation of flowering in relation to the biology and interaction between the pollen and pistil is still significantly lagging, limiting our knowledge on kinase signalling and its potential applications to crop production. To address this gap, we bring together relevant literature that were previously disconnected to present an overview of the roles of phosphoproteomic signalling pathways in modulating molecular and cellular regulation within specific tissues at different morphological stages of flowering. This review is intended to stimulate research, with the potential to increase crop productivity by providing a platform for novel molecular tools.

Keywords: Arabidopsis thaliana; crops; flowering; kinase and phosphatase signalling; phosphorylation; signal transduction.
